A signal access-control issue was discovered in the Linux kernel before 5.6.5, aka CID-7395ea4e65c2. Because exec_id in include/linux/sched.h is only 32 bits, an integer overflow can interfere with a do_notify_parent protection mechanism. A child process can send an arbitrary signal to a parent process in a different security domain. Exploitation limitations include the amount of elapsed time before an integer overflow occurs, and the lack of scenarios where signals to a parent process present a substantial operational threat.

"description": "According to the versions of the kernel packages installed, the EulerOS Virtualization installation on the remote host is affected by the following vulnerabilities :\n\n - In the Linux kernel 5.4.0-rc2, there is a use-after-free (read) in the __blk_add_trace function in kernel/trace/blktrace.c (which is used to fill out a blk_io_trace structure and place it in a per-cpu sub-buffer).(CVE-2019-19768)\n\n - The Linux kernel through 5.3.13 has a start_offset+size Integer Overflow in cpia2_remap_buffer in drivers/media/usb/cpia2/cpia2_core.c because cpia2 has its own mmap implementation. This allows local users (with /dev/video0 access) to obtain read and write permissions on kernel physical pages, which can possibly result in a privilege escalation.(CVE-2019-18675)\n\n - An issue was discovered in the Linux kernel through 5.5.6. set_fdc in drivers/block/floppy.c leads to a wait_til_ready out-of-bounds read because the FDC index is not checked for errors before assigning it, aka CID-2e90ca68b0d2.(CVE-2020-9383)\n\n - There is a use-after-free vulnerability in the Linux kernel through 5.5.2 in the vgacon_invert_region function in drivers/video/console/vgacon.c.(CVE-2020-8649)\n\n - There is a use-after-free vulnerability in the Linux kernel through 5.5.2 in the vc_do_resize function in drivers/tty/vt/vt.c.(CVE-2020-8647)\n\n - The time subsystem in the Linux kernel, when CONFIG_TIMER_STATS is enabled, allows local users to discover real PID values (as distinguished from PID values inside a PID namespace) by reading the /proc/timer_list file, related to the print_timer function in kernel/time/timer_list.c and the\n __timer_stats_timer_set_start_info function in kernel/time/timer.c.(CVE-2017-5967)\n\n - ** RESERVED ** This candidate has been reserved by an organization or individual that will use it when announcing a new security problem. When the candidate has been publicized, the details for this candidate will be provided.(CVE-2014-8181)\n\n - ext4_protect_reserved_inode in fs/ext4/block_validity.c in the Linux kernel through 5.5.3 allows attackers to cause a denial of service (soft lockup) via a crafted journal size.(CVE-2020-8992)\n\n - ** REJECT ** DO NOT USE THIS CANDIDATE NUMBER.\n ConsultIDs: CVE-2020-12826. Reason: This candidate is a duplicate of CVE-2020-12826. Notes: All CVE users should reference CVE-2020-12826 instead of this candidate. All references and descriptions in this candidate have been removed to prevent accidental usage.(CVE-2020-10741)\n\n - A signal access-control issue was discovered in the Linux kernel before 5.6.5, aka CID-7395ea4e65c2.\n Because exec_id in include/linux/sched.h is only 32 bits, an integer overflow can interfere with a do_notify_parent protection mechanism. A child process can send an arbitrary signal to a parent process in a different security domain. Exploitation limitations include the amount of elapsed time before an integer overflow occurs, and the lack of scenarios where signals to a parent process present a substantial operational threat.(CVE-2020-12826)\n\n - gadget_dev_desc_UDC_store in drivers/usb/gadget/configfs.c in the Linux kernel through 5.6.13 relies on kstrdup without considering the possibility of an internal '\\0' value, which allows attackers to trigger an out-of-bounds read, aka CID-15753588bcd4.(CVE-2020-13143)\n\n - An issue was discovered in the Linux kernel through 5.6.11. sg_write lacks an sg_remove_request call in a certain failure case, aka CID-83c6f2390040.(CVE-2020-12770)\n\n - An issue was found in Linux kernel before 5.5.4.\n mwifiex_ret_wmm_get_status() in drivers/net/wireless/marvell/mwifiex/wmm.c allows a remote AP to trigger a heap-based buffer overflow because of an incorrect memcpy, aka CID-3a9b153c5591.(CVE-2020-12654)\n\n - An issue was found in Linux kernel before 5.5.4. The mwifiex_cmd_append_vsie_tlv() function in drivers/net/wireless/marvell/mwifiex/scan.c allows local users to gain privileges or cause a denial of service because of an incorrect memcpy and buffer overflow, aka CID-b70261a288ea.(CVE-2020-12653)\n\n - usb_sg_cancel in drivers/usb/core/message.c in the Linux kernel before 5.6.8 has a use-after-free because a transfer occurs without a reference, aka CID-056ad39ee925.(CVE-2020-12464)\n\n - The __mptctl_ioctl function in drivers/message/fusion/mptctl.c in the Linux kernel before 5.4.14 allows local users to hold an incorrect lock during the ioctl operation and trigger a race condition, i.e., a 'double fetch' vulnerability, aka CID-28d76df18f0a. NOTE: the vendor states 'The security impact of this bug is not as bad as it could have been because these operations are all privileged and root already has enormous destructive power.'(CVE-2020-12652)\n\n - In the Linux kernel before 5.6.1, drivers/media/usb/gspca/xirlink_cit.c (aka the Xirlink camera USB driver) mishandles invalid descriptors, aka CID-a246b4d54770.(CVE-2020-11668)\n\n - An issue was discovered in the stv06xx subsystem in the Linux kernel before 5.6.1.\n drivers/media/usb/gspca/stv06xx/stv06xx.c and drivers/media/usb/gspca/stv06xx/stv06xx_pb0100.c mishandle invalid descriptors, as demonstrated by a NULL pointer dereference, aka CID-485b06aadb93.(CVE-2020-11609)\n\n - An issue was discovered in the Linux kernel before 5.6.1. drivers/media/usb/gspca/ov519.c allows NULL pointer dereferences in ov511_mode_init_regs and ov518_mode_init_regs when there are zero endpoints, aka CID-998912346c0d.(CVE-2020-11608)\n\n - ** DISPUTED ** An issue was discovered in the Linux kernel through 5.6.2. mpol_parse_str in mm/mempolicy.c has a stack-based out-of-bounds write because an empty nodelist is mishandled during mount option parsing, aka CID-aa9f7d5172fa.

This is related to F2FS_P_SB in fs/f2fs/f2fs.h.(CVE-2019-19815)\n\n - ** DISPUTED ** __btrfs_free_extent in fs/btrfs/extent-tree.c in the Linux kernel through 5.3.12 calls btrfs_print_leaf in a certain ENOENT case, which allows local users to obtain potentially sensitive information about register values via the dmesg program. NOTE: The BTRFS development team disputes this issues as not being a vulnerability because '1) The kernel provide facilities to restrict access to dmesg - dmesg_restrict=1 sysctl option. So it's really up to the system administrator to judge whether dmesg access shall be disallowed or not. 2) WARN/WARN_ON are widely used macros in the linux kernel. If this CVE is considered valid this would mean there are literally thousands CVE lurking in the kernel\n - something which clearly is not the case.'(CVE-2019-19039)\n\n - ext4_empty_dir in fs/ext4/namei.c in the Linux kernel through 5.3.12 allows a NULL pointer dereference because ext4_read_dirblock(inode,0,DIRENT_HTREE) can be zero.(CVE-2019-19037)\n\n - btrfs_root_node in fs/btrfs/ctree.c in the Linux kernel through 5.3.12 allows a NULL pointer dereference because rcu_dereference(root->node) can be zero.(CVE-2019-19036)\n\n - ** DISPUTED ** In the Linux kernel 4.19.83, there is a use-after-free (read) in the debugfs_remove function in fs/debugfs/inode.c (which is used to remove a file or directory in debugfs that was previously created with a call to another debugfs function such as debugfs_create_file). NOTE: Linux kernel developers dispute this issue as not being an issue with debugfs, instead this is an issue with misuse of debugfs within blktrace.(CVE-2019-19770)\n\n - An issue was discovered in slc_bump in drivers/net/can/slcan.c in the Linux kernel through 5.6.2.

A local user could exploit this to cause a denial of service (filesystem corruption).\n\nCVE-2018-14610, CVE-2018-14611, CVE-2018-14612, CVE-2018-14613\n\nWen Xu from SSLab at Gatech reported that crafted Btrfs volumes could trigger a crash (Oops) and/or out-of-bounds memory access. An attacker able to mount such a volume could use this to cause a denial of service or possibly for privilege escalation.\n\nCVE-2019-5108\n\nMitchell Frank of Cisco discovered that when the IEEE 802.11 (WiFi) stack was used in AP mode with roaming, it would trigger roaming for a newly associated station before the station was authenticated. An attacker within range of the AP could use this to cause a denial of service, either by filling up a switching table or by redirecting traffic away from other stations.\n\nCVE-2019-19319\n\nJungyeon discovered that a crafted filesystem can cause the ext4 implementation to deallocate or reallocate journal blocks. A user permitted to mount filesystems could use this to cause a denial of service (crash), or possibly for privilege escalation.\n\nCVE-2019-19447\n\nIt was discovered that the ext4 filesystem driver did not safely handle unlinking of an inode that, due to filesystem corruption, already has a link count of 0. An attacker able to mount arbitrary ext4 volumes could use this to cause a denial of service (memory corruption or crash) or possibly for privilege escalation.\n\nCVE-2019-19768\n\nTristan Madani reported a race condition in the blktrace debug facility that could result in a use-after-free. A local user able to trigger removal of block devices could possibly use this to cause a denial of service (crash) or for privilege escalation.\n\nCVE-2019-20636\n\nThe syzbot tool found that the input subsystem did not fully validate keycode changes, which could result in a heap out-of-bounds write. A local user permitted to access the device node for an input or VT device could possibly use this to cause a denial of service (crash or memory corruption) or for privilege escalation.\n\nCVE-2020-0009\n\nJann Horn reported that the Android ashmem driver did not prevent read-only files from being memory-mapped and then remapped as read-write. However, Android drivers are not enabled in Debian kernel configurations.\n\nCVE-2020-0543\n\nResearchers at VU Amsterdam discovered that on some Intel CPUs supporting the RDRAND and RDSEED instructions, part of a random value generated by these instructions may be used in a later speculative execution on any core of the same physical CPU. Depending on how these instructions are used by applications, a local user or VM guest could use this to obtain sensitive information such as cryptographic keys from other users or VMs.\n\nThis vulnerability can be mitigated by a microcode update, either as part of system firmware (BIOS) or through the intel-microcode package in Debian's non-free archive section. This kernel update only provides reporting of the vulnerability and the option to disable the mitigation if it is not needed.\n\nCVE-2020-1749\n\nXiumei Mu reported that some network protocols that can run on top of IPv6 would bypass the Transformation (XFRM) layer used by IPsec, IPcomp/IPcomp6, IPIP, and IPv6 Mobility. This could result in disclosure of information over the network, since it would not be encrypted or routed according to the system policy.\n\nCVE-2020-2732\n\nPaulo Bonzini discovered that the KVM implementation for Intel processors did not properly handle instruction emulation for L2 guests when nested virtualization is enabled. This could allow an L2 guest to cause privilege escalation, denial of service, or information leaks in the L1 guest.\n\nCVE-2020-8647, CVE-2020-8649\n\nThe Hulk Robot tool found a potential MMIO out-of-bounds access in the vgacon driver. A local user permitted to access a virtual terminal (/dev/tty1 etc.) on a system using the vgacon driver could use this to cause a denial of service (crash or memory corruption) or possibly for privilege escalation.\n\nCVE-2020-8648\n\nThe syzbot tool found a race condition in the the virtual terminal driver, which could result in a use-after-free. A local user permitted to access a virtual terminal could use this to cause a denial of service (crash or memory corruption) or possibly for privilege escalation.\n\nCVE-2020-9383\n\nJordy Zomer reported an incorrect range check in the floppy driver which could lead to a static out-of-bounds access. A local user permitted to access a floppy drive could use this to cause a denial of service (crash or memory corruption) or possibly for privilege escalation.\n\nCVE-2020-10690\n\nIt was discovered that the PTP hardware clock subsystem did not properly manage device lifetimes. Removing a PTP hardware clock from the system while a user process was using it could lead to a use-after-free. The security impact of this is unclear.\n\nCVE-2020-10751\n\nDmitry Vyukov reported that the SELinux subsystem did not properly handle validating multiple messages, which could allow a privileged attacker to bypass SELinux netlink restrictions.\n\nCVE-2020-10942\n\nIt was discovered that the vhost_net driver did not properly validate the type of sockets set as back-ends. A local user permitted to access /dev/vhost-net could use this to cause a stack corruption via crafted system calls, resulting in denial of service (crash) or possibly privilege escalation.\n\nCVE-2020-11494\n\nIt was discovered that the slcan (serial line CAN) network driver did not fully initialise CAN headers for received packets, resulting in an information leak from the kernel to user-space or over the CAN network.\n\nCVE-2020-11565\n\nEntropy Moe reported that the shared memory filesystem (tmpfs) did not correctly handle an 'mpol' mount option specifying an empty node list, leading to a stack-based out-of-bounds write. If user namespaces are enabled, a local user could use this to cause a denial of service (crash) or possibly for privilege escalation.\n\nCVE-2020-11608, CVE-2020-11609, CVE-2020-11668\n\nIt was discovered that the ov519, stv06xx, and xirlink_cit media drivers did not properly validate USB device descriptors. A physically present user with a specially constructed USB device could use this to cause a denial of service (crash) or possibly for privilege escalation.\n\nCVE-2020-12114\n\nPiotr Krysiuk discovered a race condition between the umount and pivot_root operations in the filesystem core (vfs). A local user with the CAP_SYS_ADMIN capability in any user namespace could use this to cause a denial of service (crash).\n\nCVE-2020-12464\n\nKyungtae Kim reported a race condition in the USB core that can result in a use-after-free. It is not clear how this can be exploited, but it could result in a denial of service (crash or memory corruption) or privilege escalation.\n\nCVE-2020-12652\n\nTom Hatskevich reported a bug in the mptfusion storage drivers. An ioctl handler fetched a parameter from user memory twice, creating a race condition which could result in incorrect locking of internal data structures. A local user permitted to access /dev/mptctl could use this to cause a denial of service (crash or memory corruption) or for privilege escalation.\n\nCVE-2020-12653\n\nIt was discovered that the mwifiex WiFi driver did not sufficiently validate scan requests, resulting a potential heap buffer overflow. A local user with CAP_NET_ADMIN capability could use this to cause a denial of service (crash or memory corruption) or possibly for privilege escalation.\n\nCVE-2020-12654\n\nIt was discovered that the mwifiex WiFi driver did not sufficiently validate WMM parameters received from an access point (AP), resulting a potential heap buffer overflow. A malicious AP could use this to cause a denial of service (crash or memory corruption) or possibly to execute code on a vulnerable system.\n\nCVE-2020-12769\n\nIt was discovered that the spi-dw SPI host driver did not properly serialise access to its internal state. The security impact of this is unclear, and this driver is not included in Debian's binary packages.\n\nCVE-2020-12770\n\nIt was discovered that the sg (SCSI generic) driver did not correctly release internal resources in a particular error case. A local user permitted to access an sg device could possibly use this to cause a denial of service (resource exhaustion).\n\nCVE-2020-12826\n\nAdam Zabrocki reported a weakness in the signal subsystem's permission checks. A parent process can choose an arbitary signal for a child process to send when it exits, but if the parent has executed a new program then the default SIGCHLD signal is sent. A local user permitted to run a program for several days could bypass this check, execute a setuid program, and then send an arbitrary signal to it.\nDepending on the setuid programs installed, this could have some security impact.\n\nCVE-2020-13143\n\nKyungtae Kim reported a potential heap out-of-bounds write in the USB gadget subsystem. A local user permitted to write to the gadget configuration filesystem could use this to cause a denial of service (crash or memory corruption) or potentially for privilege escalation.\n\nFor Debian 8 'Jessie', these problems have been fixed in version 3.16.84-1.\n\nWe recommend that you upgrade your linux packages.\n\nNOTE: Tenable Network Security has extracted the preceding description block directly from the DLA security advisory.

This could result in\ndisclosure of information over the network, since it would not be\nencrypted or routed according to the system policy.\n\nCVE-2020-2732\n\nPaulo Bonzini discovered that the KVM implementation for Intel\nprocessors did not properly handle instruction emulation for L2 guests\nwhen nested virtualization is enabled. This could allow an L2 guest to\ncause privilege escalation, denial of service, or information leaks in\nthe L1 guest.\n\nCVE-2020-8647, CVE-2020-8649\n\nThe Hulk Robot tool found a potential MMIO out-of-bounds access in the\nvgacon driver. A local user permitted to access a virtual terminal\n(/dev/tty1 etc.) on a system using the vgacon driver could use this to\ncause a denial of service (crash or memory corruption) or possibly for\nprivilege escalation.\n\nCVE-2020-8648\n\nThe syzbot tool found a race condition in the the virtual terminal\ndriver, which could result in a use-after-free. A local user permitted\nto access a virtual terminal could use this to cause a denial of\nservice (crash or memory corruption) or possibly for privilege\nescalation.\n\nCVE-2020-9383\n\nJordy Zomer reported an incorrect range check in the floppy driver\nwhich could lead to a static out-of-bounds access. A local user\npermitted to access a floppy drive could use this to cause a denial of\nservice (crash or memory corruption) or possibly for privilege\nescalation.\n\nCVE-2020-10690\n\nIt was discovered that the PTP hardware clock subsystem did not\nproperly manage device lifetimes. Removing a PTP hardware clock from\nthe system while a user process was using it could lead to a\nuse-after-free. The security impact of this is unclear.\n\nCVE-2020-10751\n\nDmitry Vyukov reported that the SELinux subsystem did not properly\nhandle validating multiple messages, which could allow a privileged\nattacker to bypass SELinux netlink restrictions.\n\nCVE-2020-10942\n\nIt was discovered that the vhost_net driver did not properly validate\nthe type of sockets set as back-ends. A local user permitted to access\n/dev/vhost-net could use this to cause a stack corruption via crafted\nsystem calls, resulting in denial of service (crash) or possibly\nprivilege escalation.\n\nCVE-2020-11494\n\nIt was discovered that the slcan (serial line CAN) network driver did\nnot fully initialise CAN headers for received packets, resulting in an\ninformation leak from the kernel to user-space or over the CAN\nnetwork.\n\nCVE-2020-11565\n\nEntropy Moe reported that the shared memory filesystem (tmpfs) did not\ncorrectly handle an 'mpol' mount option specifying an empty node list,\nleading to a stack-based out-of-bounds write. If user namespaces are\nenabled, a local user could use this to cause a denial of service\n(crash) or possibly for privilege escalation.\n\nCVE-2020-11608, CVE-2020-11609, CVE-2020-11668\n\nIt was discovered that the ov519, stv06xx, and xirlink_cit media\ndrivers did not properly validate USB device descriptors. A physically\npresent user with a specially constructed USB device could use this to\ncause a denial of service (crash) or possibly for privilege\nescalation.\n\nCVE-2020-12114\n\nPiotr Krysiuk discovered a race condition between the umount and\npivot_root operations in the filesystem core (vfs). A local user with\nthe CAP_SYS_ADMIN capability in any user namespace could use this to\ncause a denial of service (crash).\n\nCVE-2020-12464\n\nKyungtae Kim reported a race condition in the USB core that can result\nin a use-after-free. It is not clear how this can be exploited, but it\ncould result in a denial of service (crash or memory corruption) or\nprivilege escalation.\n\nCVE-2020-12652\n\nTom Hatskevich reported a bug in the mptfusion storage drivers. An\nioctl handler fetched a parameter from user memory twice, creating a\nrace condition which could result in incorrect locking of internal\ndata structures. A local user permitted to access /dev/mptctl could\nuse this to cause a denial of service (crash or memory corruption) or\nfor privilege escalation.\n\nCVE-2020-12653\n\nIt was discovered that the mwifiex WiFi driver did not sufficiently\nvalidate scan requests, resulting a potential heap buffer overflow. A\nlocal user with CAP_NET_ADMIN capability could use this to cause a\ndenial of service (crash or memory corruption) or possibly for\nprivilege escalation.\n\nCVE-2020-12654\n\nIt was discovered that the mwifiex WiFi driver did not sufficiently\nvalidate WMM parameters received from an access point (AP), resulting\na potential heap buffer overflow. A malicious AP could use this to\ncause a denial of service (crash or memory corruption) or possibly to\nexecute code on a vulnerable system.\n\nCVE-2020-12769\n\nIt was discovered that the spi-dw SPI host driver did not properly\nserialise access to its internal state. The security impact of this is\nunclear, and this driver is not included in Debian's binary packages.\n\nCVE-2020-12770\n\nIt was discovered that the sg (SCSI generic) driver did not correctly\nrelease internal resources in a particular error case. A local user\npermitted to access an sg device could possibly use this to cause a\ndenial of service (resource exhaustion).\n\nCVE-2020-12826\n\nAdam Zabrocki reported a weakness in the signal subsystem's permission\nchecks. A parent process can choose an arbitary signal for a child\nprocess to send when it exits, but if the parent has executed a new\nprogram then the default SIGCHLD signal is sent. A local user\npermitted to run a program for several days could bypass this check,\nexecute a setuid program, and then send an arbitrary signal to it.\nDepending on the setuid programs installed, this could have some\nsecurity impact.\n\nCVE-2020-13143\n\nKyungtae Kim reported a potential heap out-of-bounds write in the USB\ngadget subsystem. A local user permitted to write to the gadget\nconfiguration filesystem could use this to cause a denial of service\n(crash or memory corruption) or potentially for privilege escalation.\n\nFor Debian 8 'Jessie', these problems have been fixed in version\n3.16.84-1.\n\nWe recommend that you upgrade your linux packages.\n\nNOTE: Tenable Network Security has extracted the preceding description\nblock directly from the DLA security advisory.

The highest threat from this vulnerability is to data integrity and system availability.(CVE-2020-12654)A flaw was discovered in the XFS source in the Linux kernel. This flaw allows an attacker with the ability to mount an XFS filesystem, to trigger a denial of service while attempting to sync a file located on an XFS v5 image with crafted metadata.(CVE-2020-12655)An out-of-bounds (OOB) memory access flaw was found in the Network XDP (the eXpress Data Path) module in the Linux kernel's xdp_umem_reg function in net/xdp/xdp_umem.c.\n When a user with special user privilege of CAP_NET_ADMIN (or root) calls setsockopt to register umem ring on XDP socket, passing the headroom value larger than the available space in the chunk, it leads to an out-of-bounds write, causing panic or possible memory corruption. This flaw may lead to privilege escalation if a local end-user is granted permission to influence the execution of code in this manner.(CVE-2020-12659)A vulnerability was found in sg_write in drivers/scsi/sg.c in the SCSI generic (sg) driver subsystem. This flaw allows an attacker with local access and special user or root privileges to cause a denial of service if the allocated list is not cleaned with an invalid (Sg_fd * sfp) pointer at the time of failure, also possibly causing a kernel internal information leak problem.(CVE-2020-12770)An issue was discovered in the Linux kernel through 5.6.11. btree_gc_coalesce in drivers/md/bcache/btree.c has a deadlock if a coalescing operation fails.(CVE-2020-12771)A flaw was found in the Linux kernel loose validation of child/parent process identification handling while filtering signal handlers. A local attacker is able to abuse this flaw to bypass checks to send any signal to a privileged process.(CVE-2020-12826)A flaw was found in the Linux kernel, where it allows userspace processes, for example, a guest VM, to directly access h/w devices via its VFIO driver modules. The VFIO modules allow users to enable or disable access to the devices' MMIO memory address spaces. If a user attempts to access the read/write devices' MMIO address space when it is disabled, some h/w devices issue an interrupt to the CPU to indicate a fatal error condition, crashing the system. This flaw allows a guest user or process to crash the host system resulting in a denial of service.(CVE-2020-12888)gadget_dev_desc_UDC_store in drivers/usb/gadget/configfs.c in the Linux kernel through 5.6.13 relies on kstrdup without considering the possibility of an internal '\\0' value, which allows attackers to trigger an out-of-bounds read, aka CID-15753588bcd4.(CVE-2020-13143)** DISPUTED ** An issue was discovered in the Linux kernel through 5.7.1.\n drivers/tty/vt/keyboard.c has an integer overflow if k_ascii is called several times in a row, aka CID-b86dab054059. NOTE: Members in the community argue that the integer overflow does not lead to a security issue in this case.(CVE-2020-13974)A use-after-free flaw was found in slcan_write_wakeup in driverset/can/slcan.c in the serial CAN module slcan. A race condition occurs when communicating with can using slcan between the write (scheduling the transmit) and closing (flushing out any pending queues) the SLCAN channel.

An unprivileged, local\n attacker can use this flaw to infer values returned by\n affected instructions known to be commonly used during\n cryptographic operations that rely on uniqueness,\n secrecy, or both.(CVE-2020-0543)A flaw was found in the\n Linux kernel's implementation of the BTRFS file system.\n A local attacker, with the ability to mount a file\n system, can create a use-after-free memory fault after\n the file system has been unmounted. This may lead to\n memory corruption or privilege\n escalation.(CVE-2019-19377)A NULL pointer dereference\n flaw may occur in the Linux kernel's relay_open in\n kernel/relay.c. if the alloc_percpu() function is not\n validated in time of failure and used as a valid\n address for access. An attacker could use this flaw to\n cause a denial of service.(CVE-2019-19462)A NULL\n pointer dereference flaw was found in\n tw5864_handle_frame function in\n drivers/media/pci/tw5864/tw5864-video.c in the TW5864\n Series Video media driver. The pointer 'vb' is\n assigned, but not validated before its use, and can\n lead to a denial of service. This flaw allows a local\n attacker with special user or root privileges to crash\n the system or leak internal kernel\n information.(CVE-2019-20806)go7007_snd_init in\n drivers/media/usb/go7007/snd-go7007.c in the Linux\n kernel before 5.6 does not call snd_card_free for a\n failure path, which causes a memory leak, aka\n CID-9453264ef586.(CVE-2019-20810)An issue was\n discovered in the Linux kernel before 5.0.6. In\n rx_queue_add_kobject() and netdev_queue_add_kobject()\n in net/coreet-sysfs.c, a reference count is mishandled,\n aka CID-a3e23f719f5c.(CVE-2019-20811)A flaw was found\n in the way the af_packet functionality in the Linux\n kernel handled the retirement timer setting for\n TPACKET_v3 when getting settings from the underlying\n network device errors out. This flaw allows a local\n user who can open the af_packet domain socket and who\n can hit the error path, to use this vulnerability to\n starve the system.(CVE-2019-20812)A NULL pointer\n dereference flaw was found in the Linux kernel's\n SELinux subsystem. This flaw occurs while importing the\n Commercial IP Security Option (CIPSO) protocol's\n category bitmap into the SELinux extensible bitmap via\n the' ebitmap_netlbl_import' routine. While processing\n the CIPSO restricted bitmap tag in the\n 'cipso_v4_parsetag_rbm' routine, it sets the security\n attribute to indicate that the category bitmap is\n present, even if it has not been allocated. This issue\n leads to a NULL pointer dereference issue while\n importing the same category bitmap into SELinux. This\n flaw allows a remote network user to crash the system\n kernel, resulting in a denial of\n service.(CVE-2020-10711)A flaw was found in the Linux\n kernel's SELinux LSM hook implementation, where it\n anticipated the skb would only contain a single Netlink\n message. The hook incorrectly validated the first\n Netlink message in the skb only, to allow or deny the\n rest of the messages within the skb with the granted\n permissions and without further processing. At this\n time, there is no known ability for an attacker to\n abuse this flaw.(CVE-2020-10751)A flaw was found in the\n Linux Kernel in versions after 4.5-rc1 in the way\n mremap handled DAX Huge Pages. This flaw allows a local\n attacker with access to a DAX enabled storage to\n escalate their privileges on the\n system.(CVE-2020-10757)A logic bug flaw was found in\n the Linux kernel's implementation of SSBD. A bug in the\n logic handling allows an attacker with a local account\n to disable SSBD protection during a context switch when\n additional speculative execution mitigations are in\n place. This issue was introduced when the per\n task/process conditional STIPB switching was added on\n top of the existing SSBD switching. The highest threat\n from this vulnerability is to\n confidentiality.(CVE-2020-10766)A flaw was found in the\n Linux kernel's implementation of the Enhanced IBPB\n (Indirect Branch Prediction Barrier). The IBPB\n mitigation will be disabled when STIBP is not available\n or when the Enhanced Indirect Branch Restricted\n Speculation (IBRS) is available. This flaw allows a\n local attacker to perform a Spectre V2 style attack\n when this configuration is active. The highest threat\n from this vulnerability is to\n confidentiality.(CVE-2020-10767)A flaw was found in the\n prctl() function, where it can be used to enable\n indirect branch speculation after it has been disabled.\n This call incorrectly reports it as being 'force\n disabled' when it is not and opens the system to\n Spectre v2 attacks. The highest threat from this\n vulnerability is to confidentiality.(CVE-2020-10768)A\n flaw was found in the ZRAM kernel module, where a user\n with a local account and the ability to read the\n /sys/class/zram-control/hot_add file can create ZRAM\n device nodes in the /dev/ directory. This read\n allocates kernel memory and is not accounted for a user\n that triggers the creation of that ZRAM device. With\n this vulnerability, continually reading the device may\n consume a large amount of system memory and cause the\n Out-of-Memory (OOM) killer to activate and terminate\n random userspace processes, possibly making the system\n inoperable.(CVE-2020-10781)A stack buffer overflow\n issue was found in the get_raw_socket() routine of the\n Host kernel accelerator for virtio net (vhost-net)\n driver. It could occur while doing an\n ictol(VHOST_NET_SET_BACKEND) call, and retrieving\n socket name in a kernel stack variable via\n get_raw_socket(). A user able to perform ioctl(2) calls\n on the '/dev/vhost-net' device may use this flaw to\n crash the kernel resulting in DoS\n issue.(CVE-2020-10942)A flaw was found in the Linux\n kernel's implementation of the pivot_root syscall. This\n flaw allows a local privileged user (root outside or\n root inside a privileged container) to exploit a race\n condition to manipulate the reference count of the root\n filesystem. To be able to abuse this flaw, the process\n or user calling pivot_root must have advanced\n permissions. The highest threat from this vulnerability\n is to system availability.(CVE-2020-12114)A\n use-after-free flaw was found in usb_sg_cancel in\n drivers/usb/core/message.c in the USB core subsystem.\n This flaw allows a local attacker with a special user\n or root privileges to crash the system due to a race\n problem in the scatter-gather cancellation and transfer\n completion in usb_sg_wait. This vulnerability can also\n lead to a leak of internal kernel\n information.(CVE-2020-12464)A memory overflow and data\n corruption flaw were found in the Mediatek MT76 driver\n module for WiFi in mt76_add_fragment in\n driverset/wireless/mediatek/mt76/dma.c. An oversized\n packet with too many rx fragments causes an overflow\n and corruption in memory of adjacent pages. A local\n attacker with a special user or root privileges can\n cause a denial of service or a leak of internal kernel\n information.(CVE-2020-12465)A vulnerability was found\n in __mptctl_ioctl in drivers/message/fusion/mptctl.c in\n Fusion MPT base driver 'mptctl' in the SCSI device\n module, where an incorrect lock leads to a race\n problem. This flaw allows an attacker with local access\n and special user (or root) privileges to cause a denial\n of service.(CVE-2020-12652)A flaw was found in the way\n the mwifiex_cmd_append_vsie_tlv() in Linux kernel's\n Marvell WiFi-Ex driver handled vendor specific\n information elements. A local user could use this flaw\n to escalate their privileges on the\n system.(CVE-2020-12653)A flaw was found in the Linux\n kernel. The Marvell mwifiex driver allows a remote WiFi\n access point to trigger a heap-based memory buffer\n overflow due to an incorrect memcpy operation. The\n highest threat from this vulnerability is to data\n integrity and system availability.(CVE-2020-12654)A\n flaw was discovered in the XFS source in the Linux\n kernel. This flaw allows an attacker with the ability\n to mount an XFS filesystem, to trigger a denial of\n service while attempting to sync a file located on an\n XFS v5 image with crafted metadata.(CVE-2020-12655)An\n out-of-bounds (OOB) memory access flaw was found in the\n Network XDP (the eXpress Data Path) module in the Linux\n kernel's xdp_umem_reg function in net/xdp/xdp_umem.c.\n When a user with special user privilege of\n CAP_NET_ADMIN (or root) calls setsockopt to register\n umem ring on XDP socket, passing the headroom value\n larger than the available space in the chunk, it leads\n to an out-of-bounds write, causing panic or possible\n memory corruption. This flaw may lead to privilege\n escalation if a local end-user is granted permission to\n influence the execution of code in this\n manner.(CVE-2020-12659)A vulnerability was found in\n sg_write in drivers/scsi/sg.c in the SCSI generic (sg)\n driver subsystem. This flaw allows an attacker with\n local access and special user or root privileges to\n cause a denial of service if the allocated list is not\n cleaned with an invalid (Sg_fd * sfp) pointer at the\n time of failure, also possibly causing a kernel\n internal information leak problem.(CVE-2020-12770)An\n issue was discovered in the Linux kernel through\n 5.6.11. btree_gc_coalesce in drivers/md/bcache/btree.c\n has a deadlock if a coalescing operation\n fails.(CVE-2020-12771)A flaw was found in the Linux\n kernel loose validation of child/parent process\n identification handling while filtering signal\n handlers. A local attacker is able to abuse this flaw\n to bypass checks to send any signal to a privileged\n process.(CVE-2020-12826)A flaw was found in the Linux\n kernel, where it allows userspace processes, for\n example, a guest VM, to directly access h/w devices via\n its VFIO driver modules. The VFIO modules allow users\n to enable or disable access to the devices' MMIO memory\n address spaces. If a user attempts to access the\n read/write devices' MMIO address space when it is\n disabled, some h/w devices issue an interrupt to the\n CPU to indicate a fatal error condition, crashing the\n system. This flaw allows a guest user or process to\n crash the host system resulting in a denial of\n service.(CVE-2020-12888)gadget_dev_desc_UDC_store in\n drivers/usb/gadget/configfs.c in the Linux kernel\n through 5.6.13 relies on kstrdup without considering\n the possibility of an internal '\\0' value, which allows\n attackers to trigger an out-of-bounds read, aka\n CID-15753588bcd4.(CVE-2020-13143)** DISPUTED ** An\n issue was discovered in the Linux kernel through 5.7.1.\n drivers/tty/vt/keyboard.c has an integer overflow if\n k_ascii is called several times in a row, aka\n CID-b86dab054059. NOTE: Members in the community argue\n that the integer overflow does not lead to a security\n issue in this case.(CVE-2020-13974)A use-after-free\n flaw was found in slcan_write_wakeup in\n driverset/can/slcan.c in the serial CAN module slcan. A\n race condition occurs when communicating with can using\n slcan between the write (scheduling the transmit) and\n closing (flushing out any pending queues) the SLCAN\n channel. This flaw allows a local attacker with special\n user or root privileges to cause a denial of service or\n a kernel information leak. The highest threat from this\n vulnerability is to system\n availability.(CVE-2020-14416)In the Linux kernel\n through 5.7.6, usbtest_disconnect in\n drivers/usb/misc/usbtest.c has a memory leak, aka\n CID-28ebeb8db770.(CVE-2020-15393)The Linux kernel\n through 5.7.11 allows remote attackers to make\n observations that help to obtain sensitive information\n about the internal state of the network RNG, aka\n CID-f227e3ec3b5c. This is related to\n drivers/char/random.c and\n kernel/time/timer.c.(CVE-2020-16166)A flaw was found in\n the Linux kernel's implementation of Userspace core\n dumps. This flaw allows an attacker with a local\n account to crash a trivial program and exfiltrate\n private kernel data.(CVE-2020-10732)A flaw null pointer\n dereference in the Linux kernel cgroupv2 subsystem in\n versions before 5.7.10 was found in the way when reboot\n the system.

"description": "The remote Oracle Linux 7 host has packages installed that are affected by multiple vulnerabilities as referenced in the ELSA-2020-4060 advisory.\n\n - An issue was discovered in the Linux kernel before 4.20. There is a race condition in smp_task_timedout() and smp_task_done() in drivers/scsi/libsas/sas_expander.c, leading to a use-after-free. (CVE-2018-20836)\n\n - An issue was discovered in drivers/i2c/i2c-core-smbus.c in the Linux kernel before 4.14.15. There is an out of bounds write in the function i2c_smbus_xfer_emulated. (CVE-2017-18551)\n\n - ieee802154_create in net/ieee802154/socket.c in the AF_IEEE802154 network module in the Linux kernel through 5.3.2 does not enforce CAP_NET_RAW, which means that unprivileged users can create a raw socket, aka CID-e69dbd4619e7. (CVE-2019-17053)\n\n - An issue was discovered in the Linux kernel before 5.2.3. There is a NULL pointer dereference caused by a malicious USB device in the drivers/media/usb/zr364xx/zr364xx.c driver. (CVE-2019-15217)\n\n - In the Linux kernel before 5.0, a memory leak exists in sit_init_net() in net/ipv6/sit.c when register_netdev() fails to register sitn->fb_tunnel_dev, which may cause denial of service, aka CID-07f12b26e21a. (CVE-2019-16994)\n\n - base_sock_create in drivers/isdn/mISDN/socket.c in the AF_ISDN network module in the Linux kernel through 5.3.2 does not enforce CAP_NET_RAW, which means that unprivileged users can create a raw socket, aka CID-b91ee4aa2a21. (CVE-2019-17055)\n\n - In the Linux kernel before 5.1.13, there is a memory leak in drivers/scsi/libsas/sas_expander.c when SAS expander discovery fails. This will cause a BUG and denial of service. (CVE-2019-15807)\n\n - drivers/scsi/qla2xxx/qla_os.c in the Linux kernel 5.2.14 does not check the alloc_workqueue return value, leading to a NULL pointer dereference. (CVE-2019-16233)\n\n - An issue was discovered in the Linux kernel before 5.0.5. There is a use-after-free issue when hci_uart_register_dev() fails in hci_uart_set_proto() in drivers/bluetooth/hci_ldisc.c. (CVE-2019-15917)\n\n - An out-of-bounds memory write issue was found in the Linux Kernel, version 3.13 through 5.4, in the way the Linux kernel's KVM hypervisor handled the 'KVM_GET_EMULATED_CPUID' ioctl(2) request to get CPUID features emulated by the KVM hypervisor. A user or process able to access the '/dev/kvm' device could use this flaw to crash the system, resulting in a denial of service. (CVE-2019-19332)\n\n - drivers/net/fjes/fjes_main.c in the Linux kernel 5.2.14 does not check the alloc_workqueue return value, leading to a NULL pointer dereference. (CVE-2019-16231)\n\n - In the Linux kernel before 5.0.6, there is a NULL pointer dereference in drop_sysctl_table() in fs/proc/proc_sysctl.c, related to put_links, aka CID-23da9588037e. (CVE-2019-20054)\n\n - mwifiex_tm_cmd in drivers/net/wireless/marvell/mwifiex/cfg80211.c in the Linux kernel before 5.1.6 has some error-handling cases that did not free allocated hostcmd memory, aka CID-003b686ace82. This will cause a memory leak and denial of service. (CVE-2019-20095)\n\n - A flaw was discovered in the way that the KVM hypervisor handled instruction emulation for an L2 guest when nested virtualisation is enabled. Under some circumstances, an L2 guest may trick the L0 guest into accessing sensitive L1 resources that should be inaccessible to the L2 guest. (CVE-2020-2732)\n\n - In the Linux kernel before 5.5.8, get_raw_socket in drivers/vhost/net.c lacks validation of an sk_family field, which might allow attackers to trigger kernel stack corruption via crafted system calls.\n (CVE-2020-10942)\n\n - An issue was discovered in the Linux kernel 3.16 through 5.5.6. set_fdc in drivers/block/floppy.c leads to a wait_til_ready out-of-bounds read because the FDC index is not checked for errors before assigning it, aka CID-2e90ca68b0d2. (CVE-2020-9383)\n\n - In the Linux kernel before 5.3.7, there is a use-after-free bug that can be caused by a malicious USB device in the drivers/usb/misc/adutux.c driver, aka CID-44efc269db79. (CVE-2019-19523)\n\n - There is a use-after-free vulnerability in the Linux kernel through 5.5.2 in the vc_do_resize function in drivers/tty/vt/vt.c. (CVE-2020-8647)\n\n - There is a use-after-free vulnerability in the Linux kernel through 5.5.2 in the vgacon_invert_region function in drivers/video/console/vgacon.c. (CVE-2020-8649)\n\n - In the Linux kernel before 5.3.12, there is a use-after-free bug that can be caused by a malicious USB device in the drivers/input/ff-memless.c driver, aka CID-fa3a5a1880c9. (CVE-2019-19524)\n\n - In the Linux kernel before 5.2.10, there is a race condition bug that can be caused by a malicious USB device in the USB character device driver layer, aka CID-303911cfc5b9. This affects drivers/usb/core/file.c. (CVE-2019-19537)\n\n - In the Linux kernel before 5.4.12, drivers/input/input.c has out-of-bounds writes via a crafted keycode table, as demonstrated by input_set_keycode, aka CID-cb222aed03d7. (CVE-2019-20636)\n\n - In the Linux kernel before 5.3.11, there is an info-leak bug that can be caused by a malicious USB device in the drivers/net/can/usb/peak_usb/pcan_usb_core.c driver, aka CID-f7a1337f0d29. (CVE-2019-19534)\n\n - A flaw was found in the Linux kernel's implementation of some networking protocols in IPsec, such as VXLAN and GENEVE tunnels over IPv6. When an encrypted tunnel is created between two hosts, the kernel isn't correctly routing tunneled data over the encrypted link; rather sending the data unencrypted. This would allow anyone in between the two endpoints to read the traffic unencrypted. The main threat from this vulnerability is to data confidentiality. (CVE-2020-1749)\n\n - The Linux kernel before 5.4.2 mishandles ext4_expand_extra_isize, as demonstrated by use-after-free errors in __ext4_expand_extra_isize and ext4_xattr_set_entry, related to fs/ext4/inode.c and fs/ext4/super.c, aka CID-4ea99936a163. (CVE-2019-19767)\n\n - A memory leak in the alloc_sgtable() function in drivers/net/wireless/intel/iwlwifi/fw/dbg.c in the Linux kernel through 5.3.11 allows attackers to cause a denial of service (memory consumption) by triggering alloc_page() failures, aka CID-b4b814fec1a5. (CVE-2019-19058)\n\n - There is a use-after-free in kernel versions before 5.5 due to a race condition between the release of ptp_clock and cdev while resource deallocation. When a (high privileged) process allocates a ptp device file (like /dev/ptpX) and voluntarily goes to sleep. During this time if the underlying device is removed, it can cause an exploitable condition as the process wakes up to terminate and clean all attached files.\n The system crashes due to the cdev structure being invalid (as already freed) which is pointed to by the inode. (CVE-2020-10690)\n\n - An issue was discovered in the Linux kernel through 5.6.11. sg_write lacks an sg_remove_request call in a certain failure case, aka CID-83c6f2390040. (CVE-2020-12770)\n\n - In the Linux kernel before 5.3.11, sound/core/timer.c has a use-after-free caused by erroneous code refactoring, aka CID-e7af6307a8a5. This is related to snd_timer_open and snd_timer_close_locked. The timeri variable was originally intended to be for a newly created timer instance, but was used for a different purpose after refactoring.

(CVE-2020-8647)\n\n - There is a use-after-free vulnerability in the Linux kernel through 5.5.2 in the n_tty_receive_buf_common function in drivers/tty/n_tty.c. (CVE-2020-8648)\n\n - There is a use-after-free vulnerability in the Linux kernel through 5.5.2 in the vgacon_invert_region function in drivers/video/console/vgacon.c. (CVE-2020-8649)\n\n - A flaw was found in the Linux kernel's implementation of Userspace core dumps. This flaw allows an attacker with a local account to crash a trivial program and exfiltrate private kernel data.\n (CVE-2020-10732)\n\n - A flaw was found in the Linux kernels SELinux LSM hook implementation before version 5.7, where it incorrectly assumed that an skb would only contain a single netlink message. The hook would incorrectly only validate the first netlink message in the skb and allow or deny the rest of the messages within the skb with the granted permission without further processing. (CVE-2020-10751)\n\n - A stack information leak flaw was found in s390/s390x in the Linux kernel's memory manager functionality, where it incorrectly writes to the /proc/sys/vm/cmm_timeout file. This flaw allows a local user to see the kernel data. (CVE-2020-10773)\n\n - A memory disclosure flaw was found in the Linux kernel's versions before 4.18.0-193.el8 in the sysctl subsystem when reading the /proc/sys/kernel/rh_features file. This flaw allows a local user to read uninitialized values from the kernel memory. The highest threat from this vulnerability is to confidentiality. (CVE-2020-10774)\n\n - In the Linux kernel before 5.5.8, get_raw_socket in drivers/vhost/net.c lacks validation of an sk_family field, which might allow attackers to trigger kernel stack corruption via crafted system calls.\n (CVE-2020-10942)\n\n - ** DISPUTED ** An issue was discovered in the Linux kernel through 5.6.2. mpol_parse_str in mm/mempolicy.c has a stack-based out-of-bounds write because an empty nodelist is mishandled during mount option parsing, aka CID-aa9f7d5172fa. NOTE: Someone in the security community disagrees that this is a vulnerability because the issue is a bug in parsing mount options which can only be specified by a privileged user, so triggering the bug does not grant any powers not already held.. (CVE-2020-11565)\n\n - In the Linux kernel before 5.6.1, drivers/media/usb/gspca/xirlink_cit.c (aka the Xirlink camera USB driver) mishandles invalid descriptors, aka CID-a246b4d54770. (CVE-2020-11668)\n\n - An array overflow was discovered in mt76_add_fragment in drivers/net/wireless/mediatek/mt76/dma.c in the Linux kernel before 5.5.10, aka CID-b102f0c522cf. An oversized packet with too many rx fragments can corrupt memory of adjacent pages. (CVE-2020-12465)\n\n - An issue was discovered in xfs_agf_verify in fs/xfs/libxfs/xfs_alloc.c in the Linux kernel through 5.6.10.\n Attackers may trigger a sync of excessive duration via an XFS v5 image with crafted metadata, aka CID-d0c7feaf8767. (CVE-2020-12655)\n\n - An issue was discovered in the Linux kernel before 5.6.7. xdp_umem_reg in net/xdp/xdp_umem.c has an out- of-bounds write (by a user with the CAP_NET_ADMIN capability) because of a lack of headroom validation.\n (CVE-2020-12659)\n\n - An issue was discovered in the Linux kernel through 5.6.11. sg_write lacks an sg_remove_request call in a certain failure case, aka CID-83c6f2390040. (CVE-2020-12770)\n\n - A signal access-control issue was discovered in the Linux kernel before 5.6.5, aka CID-7395ea4e65c2.\n Because exec_id in include/linux/sched.h is only 32 bits, an integer overflow can interfere with a do_notify_parent protection mechanism. A child process can send an arbitrary signal to a parent process in a different security domain. Exploitation limitations include the amount of elapsed time before an integer overflow occurs, and the lack of scenarios where signals to a parent process present a substantial operational threat. (CVE-2020-12826)\n\n - A flaw was found in the Linux kernel's futex implementation. This flaw allows a local attacker to corrupt system memory or escalate their privileges when creating a futex on a filesystem that is about to be unmounted. The highest threat from this vulnerability is to confidentiality, integrity, as well as system availability. (CVE-2020-14381)\n\n - A flaw was found in the Linux kernel's implementation of biovecs in versions before 5.9-rc7.

(CVE-2019-12614)\n\n - ** DISPUTED ** An issue was discovered in the Linux kernel through 5.6.2. mpol_parse_str in mm/mempolicy.c has a stack-based out-of-bounds write because an empty nodelist is mishandled during mount option parsing, aka CID-aa9f7d5172fa. NOTE: Someone in the security community disagrees that this is a vulnerability because the issue is a bug in parsing mount options which can only be specified by a privileged user, so triggering the bug does not grant any powers not already held.. (CVE-2020-11565)\n\n - A signal access-control issue was discovered in the Linux kernel before 5.6.5, aka CID-7395ea4e65c2.\n Because exec_id in include/linux/sched.h is only 32 bits, an integer overflow can interfere with a do_notify_parent protection mechanism. A child process can send an arbitrary signal to a parent process in a different security domain. Exploitation limitations include the amount of elapsed time before an integer overflow occurs, and the lack of scenarios where signals to a parent process present a substantial operational threat. (CVE-2020-12826)\n\n - A flaw was found in the Linux kernel's implementation of biovecs in versions before 5.9-rc7. A zero-length biovec request issued by the block subsystem could cause the kernel to enter an infinite loop, causing a denial of service. This flaw allows a local attacker with basic privileges to issue requests to a block device, resulting in a denial of service. The highest threat from this vulnerability is to system availability. (CVE-2020-25641)\n\n - In audit_free_lsm_field of auditfilter.c, there is a possible bad kfree due to a logic error in audit_data_to_entry. This could lead to local escalation of privilege with no additional execution privileges needed. User interaction is not needed for exploitation.Product: AndroidVersions: Android kernelAndroid ID: A-150693166References: Upstream kernel (CVE-2020-0444)\n\n - A flaw was found in the Linux kernel's futex implementation. This flaw allows a local attacker to corrupt system memory or escalate their privileges when creating a futex on a filesystem that is about to be unmounted. The highest threat from this vulnerability is to confidentiality, integrity, as well as system availability. (CVE-2020-14381)\n\n - In the Android kernel in the video driver there is a kernel pointer leak due to a WARN_ON statement. This could lead to local information disclosure with System execution privileges needed. User interaction is not needed for exploitation. (CVE-2019-9455)\n\n - A memory leak in the rtl8xxxu_submit_int_urb() function in drivers/net/wireless/realtek/rtl8xxxu/rtl8xxxu_core.c in the Linux kernel through 5.3.11 allows attackers to cause a denial of service (memory consumption) by triggering usb_submit_urb() failures, aka CID-a2cdd07488e6. (CVE-2019-19068)\n\n - A memory leak in the predicate_parse() function in kernel/trace/trace_events_filter.c in the Linux kernel through 5.3.11 allows attackers to cause a denial of service (memory consumption), aka CID-96c5c6e6a5b6.\n (CVE-2019-19072)\n\n - A memory disclosure flaw was found in the Linux kernel's versions before 4.18.0-193.el8 in the sysctl subsystem when reading the /proc/sys/kernel/rh_features file. This flaw allows a local user to read uninitialized values from the kernel memory. The highest threat from this vulnerability is to confidentiality. (CVE-2020-10774)\n\n - An issue was discovered in the Linux kernel before 5.2.3. An out of bounds access exists in the function hclge_tm_schd_mode_vnet_base_cfg in the file drivers/net/ethernet/hisilicon/hns3/hns3pf/hclge_tm.c.\n (CVE-2019-15925)\n\n - In the Linux kernel before 5.2, a setxattr operation, after a mount of a crafted ext4 image, can cause a slab-out-of-bounds write access because of an ext4_xattr_set_entry use-after-free in fs/ext4/xattr.c when a large old_size value is used in a memset call, aka CID-345c0dbf3a30. (CVE-2019-19319)\n\n - In the Linux kernel before 5.1.6, there is a use-after-free in serial_ir_init_module() in drivers/media/rc/serial_ir.c. (CVE-2019-19543)\n\n - fpregs_state_valid in arch/x86/include/asm/fpu/internal.h in the Linux kernel before 5.4.2, when GCC 9 is used, allows context-dependent attackers to cause a denial of service (memory corruption) or possibly have unspecified other impact because of incorrect fpu_fpregs_owner_ctx caching, as demonstrated by mishandling of signal-based non-cooperative preemption in Go 1.14 prereleases on amd64, aka CID-59c4bd853abc.\n (CVE-2019-19602)\n\n - ** DISPUTED ** In the Linux kernel 4.19.83, there is a use-after-free (read) in the debugfs_remove function in fs/debugfs/inode.c (which is used to remove a file or directory in debugfs that was previously created with a call to another debugfs function such as debugfs_create_file). NOTE: Linux kernel developers dispute this issue as not being an issue with debugfs, instead this is an issue with misuse of debugfs within blktrace. (CVE-2019-19770)\n\n - In cdev_get of char_dev.c, there is a possible use-after-free due to a race condition. This could lead to local escalation of privilege with System execution privileges needed.

NOTE: Someone in the security community disagrees that this is a vulnerability\n because the issue is a bug in parsing mount options which can only be specified by a privileged user, so\n triggering the bug does not grant any powers not already held.. (CVE-2020-11565)\n\n - A signal access-control issue was discovered in the Linux kernel before 5.6.5, aka CID-7395ea4e65c2.\n Because exec_id in include/linux/sched.h is only 32 bits, an integer overflow can interfere with a\n do_notify_parent protection mechanism. A child process can send an arbitrary signal to a parent process in\n a different security domain. Exploitation limitations include the amount of elapsed time before an integer\n overflow occurs, and the lack of scenarios where signals to a parent process present a substantial\n operational threat. (CVE-2020-12826)\n\n - A flaw was found in the Linux kernel's implementation of biovecs in versions before 5.9-rc7. A zero-length\n biovec request issued by the block subsystem could cause the kernel to enter an infinite loop, causing a\n denial of service. This flaw allows a local attacker with basic privileges to issue requests to a block\n device, resulting in a denial of service. The highest threat from this vulnerability is to system\n availability. (CVE-2020-25641)\n\n - In audit_free_lsm_field of auditfilter.c, there is a possible bad kfree due to a logic error in\n audit_data_to_entry.

This flaw allows a local user to read\n uninitialized values from the kernel memory. The highest threat from this vulnerability is to\n confidentiality. (CVE-2020-10774)\n\n - An issue was discovered in the Linux kernel before 5.2.3. An out of bounds access exists in the function\n hclge_tm_schd_mode_vnet_base_cfg in the file drivers/net/ethernet/hisilicon/hns3/hns3pf/hclge_tm.c.\n (CVE-2019-15925)\n\n - In the Linux kernel before 5.2, a setxattr operation, after a mount of a crafted ext4 image, can cause a\n slab-out-of-bounds write access because of an ext4_xattr_set_entry use-after-free in fs/ext4/xattr.c when\n a large old_size value is used in a memset call, aka CID-345c0dbf3a30. (CVE-2019-19319)\n\n - In the Linux kernel before 5.1.6, there is a use-after-free in serial_ir_init_module() in\n drivers/media/rc/serial_ir.c. (CVE-2019-19543)\n\n - fpregs_state_valid in arch/x86/include/asm/fpu/internal.h in the Linux kernel before 5.4.2, when GCC 9 is\n used, allows context-dependent attackers to cause a denial of service (memory corruption) or possibly have\n unspecified other impact because of incorrect fpu_fpregs_owner_ctx caching, as demonstrated by mishandling\n of signal-based non-cooperative preemption in Go 1.14 prereleases on amd64, aka CID-59c4bd853abc.\n (CVE-2019-19602)\n\n - ** DISPUTED ** In the Linux kernel 4.19.83, there is a use-after-free (read) in the debugfs_remove\n function in fs/debugfs/inode.c (which is used to remove a file or directory in debugfs that was previously\n created with a call to another debugfs function such as debugfs_create_file). NOTE: Linux kernel\n developers dispute this issue as not being an issue with debugfs, instead this is an issue with misuse of\n debugfs within blktrace. (CVE-2019-19770)\n\n - In cdev_get of char_dev.c, there is a possible use-after-free due to a race condition. This could lead to\n local escalation of privilege with System execution privileges needed. User interaction is not needed for\n exploitation.Product: AndroidVersions: Android-10Android ID: A-153467744 (CVE-2020-0305)\n\n - A stack information leak flaw was found in s390/s390x in the Linux kernel's memory manager functionality,\n where it incorrectly writes to the /proc/sys/vm/cmm_timeout file.

"According to the versions of the kernel packages installed, the EulerOS installation on the remote host is affected by the following vulnerabilities :\n\n - The kernel package contains the Linux kernel (vmlinuz), the core of any Linux operating system. The kernel handles the basic functions of the operating system:\n memory allocation, process allocation, device input and output, etc.Security Fix(es):In the Linux kernel before 5.5.8, get_raw_socket in drivers/vhost/ net.c lacks validation of an sk_family field, which might allow attackers to trigger kernel stack corruption via crafted system calls.(CVE-2020-10942)In the Linux kernel 5.0.21, a setxattr operation, after a mount of a crafted ext4 image, can cause a slab-out-of-bounds write access because of an ext4_xattr_set_entry use-after-free in fs/ext4/xattr.c when a large old_size value is used in a memset call.(CVE-2019-19319)In kernel/compat.c in the Linux kernel before 3.17, as used in Google Chrome OS and other products, there is a possible out-of-bounds read. restart_syscall uses uninitialized data when restarting compat_sys_nanosleep. NOTE: this is disputed because the code path is unreachable.(CVE-2014-3180)In the Linux kernel 5.4.0-rc2, there is a use-after-free (read) in the __blk_add_trace function in kernel/trace/blktrace.c (which is used to fill out a blk_io_trace structure and place it in a per-cpu sub-buffer).(CVE-2019-19768)There is a use-after-free vulnerability in the Linux kernel through 5.5.2 in the vc_do_resize function in drivers/tty/vt/vt.c.(CVE-2020-8647)There is a use-after-free vulnerability in the Linux kernel through 5.5.2 in the vgacon_invert_region function in drivers/video/console/vgacon.c.(CVE-2020-8649)drivers/g pu/drm/radeon/radeon_display.c in the Linux kernel 5.2.14 does not check the alloc_workqueue return value, leading to a NULL pointer dereference. NOTE: A third-party software maintainer states that the work queue allocation is happening during device initialization, which for a graphics card occurs during boot. It is not attacker controllable and OOM at that time is highly unlikely.(CVE-2019-16230)There is a use-after-free vulnerability in the Linux kernel through 5.5.2 in the n_tty_receive_buf_common function in drivers/tty/ n_tty.c.(CVE-2020-8648)A flaw was discovered in the way that the KVM hypervisor handled instruction emulation for an L2 guest when nested virtualisation is enabled. Under some circumstances, an L2 guest may trick the L0 guest into accessing sensitive L1 resources that should be inaccessible to the L2 guest.(CVE-2020-2732)An issue was discovered in the Linux kernel through 5.5.6. set_fdc in drivers/block/floppy.c leads to a wait_til_ready out-of-bounds read because the FDC index is not checked for errors before assigning it, aka CID-2e90ca68b0d2.(CVE-2020-9383)ext4_protect_reserved_i node in fs/ext4/block_validity.c in the Linux kernel through 5.5.3 allows attackers to cause a denial of service (soft lockup) via a crafted journal size.(CVE-2020-8992)Wi-Fi Protected Access (WPA and WPA2) allows reinstallation of the Group Temporal Key (GTK) during the group key handshake, allowing an attacker within radio range to replay frames from access points to clients.(CVE-2017-13080)Linux Kernel version 3.18 to 4.16 incorrectly handles an SG_IO ioctl on /dev/sg0 with dxfer_direction=SG_DXFER_FROM_DEV and an empty 6-byte cmdp. This may lead to copying up to 1000 kernel heap pages to the userspace. This has been fixed upstream in https://github.com/torvalds/linux/commit/a45b599ad808c3 c982fdcdc12b0b8611c2f92824 already. The problem has limited scope, as users don't usually have permissions to access SCSI devices. On the other hand, e.g. the Nero user manual suggests doing `chmod o+r+w /dev/sg*` to make the devices accessible. NOTE: third parties dispute the relevance of this report, noting that the requirement for an attacker to have both the CAP_SYS_ADMIN and CAP_SYS_RAWIO capabilities makes it 'virtually impossible to exploit.'(CVE-2018-1000204)The Linux kernel through 5.3.13 has a start_offset+size Integer Overflow in cpia2_remap_buffer in drivers/media/usb/cpia2/cpia2_core.c because cpia2 has its own mmap implementation. This allows local users (with /dev/video0 access) to obtain read and write permissions on kernel physical pages, which can possibly result in a privilege escalation.(CVE-2019-18675)arch/x86/kvm/emulate.c in the Linux kernel before 4.8.12 does not properly initialize Code Segment (CS) in certain error cases, which allows local users to obtain sensitive information from kernel stack memory via a crafted application.(CVE-2016-9756)Double free vulnerability in drivers/ net/usb/cdc_ncm.c in the Linux kernel before 4.5 allows physically proximate attackers to cause a denial of service (system crash) or possibly have unspecified other impact by inserting a USB device with an invalid USB descriptor.(CVE-2016-3951)Linux Kernel contains an out-of-bounds read flaw in the asn1_ber_decoder() function in lib/asn1_decoder.c that is triggered when decoding ASN.1 data. This may allow a remote attacker to disclose potentially sensitive memory contents.(CVE-2018-9383)Linux Kernel contains a flaw in the ip6_setup_cork() function in net/ipv6/ip6_output.c that is triggered when handling too small IPv6 MTU sizes. This may allow a local attacker to cause a crash or potentially gain elevated privileges.(CVE-2018-9389)In the Android kernel in the video driver there is a use after free due to a race condition. This could lead to local escalation of privilege with no additional execution privileges needed. User interaction is not needed for exploitation.(CVE-2019-9458)An out-of-bounds memory write issue was found in the Linux Kernel, version 3.13 through 5.4, in the way the Linux kernel's KVM hypervisor handled the 'KVM_GET_EMULATED_CPUID' ioctl(2) request to get CPUID features emulated by the KVM hypervisor. A user or process able to access the '/dev/kvm' device could use this flaw to crash the system, resulting in a denial of service.(CVE-2019-19332)kernel/sched/fair.c in the Linux kernel before 5.3.9, when cpu.cfs_quota_us is used (e.g., with Kubernetes), allows attackers to cause a denial of service against non-cpu-bound applications by generating a workload that triggers unwanted slice expiration, aka CID-de53fd7aedb1. (In other words, although this slice expiration would typically be seen with benign workloads, it is possible that an attacker could calculate how many stray requests are required to force an entire Kubernetes cluster into a low-performance state caused by slice expiration, and ensure that a DDoS attack sent that number of stray requests. An attack does not affect the stability of the kernel it only causes mismanagement of application execution.)(CVE-2019-19922)An exploitable denial-of-service vulnerability exists in the Linux kernel prior to mainline 5.3. An attacker could exploit this vulnerability by triggering AP to send IAPP location updates for stations before the required authentication process has completed. This could lead to different denial-of-service scenarios, either by causing CAM table attacks, or by leading to traffic flapping if faking already existing clients in other nearby APs of the same wireless infrastructure. An attacker can forge Authentication and Association Request packets to trigger this vulnerability.(CVE-2019-5108)A heap-based buffer overflow vulnerability was found in the Linux kernel, version kernel-2.6.32, in Marvell WiFi chip driver. A remote attacker could cause a denial of service (system crash) or, possibly execute arbitrary code, when the lbs_ibss_join_existing function is called after a STA connects to an AP.(CVE-2019-14896)A stack-based buffer overflow was found in the Linux kernel, version kernel-2.6.32, in Marvell WiFi chip driver.

This could allow the remote device to cause a denial of service (system crash) or possibly execute arbitrary code.(CVE-2019-14895)The acpi_ds_create_operands() function in drivers/acpi/acpica/dsutils.c in the Linux kernel through 4.12.9 does not flush the operand cache and causes a kernel stack dump, which allows local users to obtain sensitive information from kernel memory and bypass the KASLR protection mechanism (in the kernel through 4.9) via a crafted ACPI table.(CVE-2017-13693)Linux kernel CIFS implementation, version 4.9.0 is vulnerable to a relative paths injection in directory entry lists.(CVE-2019-10220)A heap overflow flaw was found in the Linux kernel, all versions 3.x.x and 4.x.x before 4.18.0, in Marvell WiFi chip driver. The vulnerability allows a remote attacker to cause a system crash, resulting in a denial of service, or execute arbitrary code. The highest threat with this vulnerability is with the availability of the system. If code execution occurs, the code will run with the permissions of root. This will affect both confidentiality and integrity of files on the system.(CVE-2019-14901)In the AppleTalk subsystem in the Linux kernel before 5.1, there is a potential NULL pointer dereference because register_snap_client may return NULL. This will lead to denial of service in net/appletalk/aarp.c and net/appletalk/ddp.c, as demonstrated by unregister_snap_client, aka CID-9804501fa122.(CVE-2019-19227)In the Linux kernel before 5.2.10, there is a use-after-free bug that can be caused by a malicious USB device in the drivers/usb/class/cdc-acm.c driver, aka CID-c52873e5a1ef.(CVE-2019-19530)In the Linux kernel before 5.3.9, there are multiple out-of-bounds write bugs that can be caused by a malicious USB device in the Linux kernel HID drivers, aka CID-d9d4b1e46d95.\n This affects drivers/hid/hid-axff.c, drivers/hid/hid-dr.c, drivers/hid/hid-emsff.c, drivers/hid/hid-gaff.c, drivers/hid/hid-holtekff.c, drivers/hid/hid-lg2ff.c, drivers/hid/hid-lg3ff.c, drivers/hid/hid-lg4ff.c, drivers/hid/hid-lgff.c, drivers/hid/hid-logitech-hidpp.c, drivers/hid/hid-microsoft.c, drivers/hid/hid-sony.c, drivers/hid/hid-tmff.c, and drivers/hid/hid-zpff.c.(CVE-2019-19532)A use-after-free in binder.c allows an elevation of privilege from an application to the Linux Kernel.

This may lead to copying up to\n 1000 kernel heap pages to the userspace. This has been\n fixed upstream in\n https://github.com/torvalds/linux/commit/a45b599ad808c3\n c982fdcdc12b0b8611c2f92824 already. The problem has\n limited scope, as users don't usually have permissions\n to access SCSI devices. On the other hand, e.g. the\n Nero user manual suggests doing `chmod o+r+w /dev/sg*`\n to make the devices accessible. NOTE: third parties\n dispute the relevance of this report, noting that the\n requirement for an attacker to have both the\n CAP_SYS_ADMIN and CAP_SYS_RAWIO capabilities makes it\n 'virtually impossible to exploit.'(CVE-2018-1000204)The\n Linux kernel through 5.3.13 has a start_offset+size\n Integer Overflow in cpia2_remap_buffer in\n drivers/media/usb/cpia2/cpia2_core.c because cpia2 has\n its own mmap implementation. This allows local users\n (with /dev/video0 access) to obtain read and write\n permissions on kernel physical pages, which can\n possibly result in a privilege\n escalation.(CVE-2019-18675)arch/x86/kvm/emulate.c in\n the Linux kernel before 4.8.12 does not properly\n initialize Code Segment (CS) in certain error cases,\n which allows local users to obtain sensitive\n information from kernel stack memory via a crafted\n application.(CVE-2016-9756)Double free vulnerability in\n drivers/ net/usb/cdc_ncm.c in the Linux kernel before\n 4.5 allows physically proximate attackers to cause a\n denial of service (system crash) or possibly have\n unspecified other impact by inserting a USB device with\n an invalid USB descriptor.(CVE-2016-3951)Linux Kernel\n contains an out-of-bounds read flaw in the\n asn1_ber_decoder() function in lib/asn1_decoder.c that\n is triggered when decoding ASN.1 data. This may allow a\n remote attacker to disclose potentially sensitive\n memory contents.(CVE-2018-9383)Linux Kernel contains a\n flaw in the ip6_setup_cork() function in\n net/ipv6/ip6_output.c that is triggered when handling\n too small IPv6 MTU sizes. This may allow a local\n attacker to cause a crash or potentially gain elevated\n privileges.(CVE-2018-9389)In the Android kernel in the\n video driver there is a use after free due to a race\n condition. This could lead to local escalation of\n privilege with no additional execution privileges\n needed. User interaction is not needed for\n exploitation.(CVE-2019-9458)An out-of-bounds memory\n write issue was found in the Linux Kernel, version 3.13\n through 5.4, in the way the Linux kernel's KVM\n hypervisor handled the 'KVM_GET_EMULATED_CPUID'\n ioctl(2) request to get CPUID features emulated by the\n KVM hypervisor. A user or process able to access the\n '/dev/kvm' device could use this flaw to crash the\n system, resulting in a denial of\n service.(CVE-2019-19332)kernel/sched/fair.c in the\n Linux kernel before 5.3.9, when cpu.cfs_quota_us is\n used (e.g., with Kubernetes), allows attackers to cause\n a denial of service against non-cpu-bound applications\n by generating a workload that triggers unwanted slice\n expiration, aka CID-de53fd7aedb1. (In other words,\n although this slice expiration would typically be seen\n with benign workloads, it is possible that an attacker\n could calculate how many stray requests are required to\n force an entire Kubernetes cluster into a\n low-performance state caused by slice expiration, and\n ensure that a DDoS attack sent that number of stray\n requests. An attack does not affect the stability of\n the kernel it only causes mismanagement of application\n execution.)(CVE-2019-19922)An exploitable\n denial-of-service vulnerability exists in the Linux\n kernel prior to mainline 5.3. An attacker could exploit\n this vulnerability by triggering AP to send IAPP\n location updates for stations before the required\n authentication process has completed. This could lead\n to different denial-of-service scenarios, either by\n causing CAM table attacks, or by leading to traffic\n flapping if faking already existing clients in other\n nearby APs of the same wireless infrastructure. An\n attacker can forge Authentication and Association\n Request packets to trigger this\n vulnerability.(CVE-2019-5108)A heap-based buffer\n overflow vulnerability was found in the Linux kernel,\n version kernel-2.6.32, in Marvell WiFi chip driver. A\n remote attacker could cause a denial of service (system\n crash) or, possibly execute arbitrary code, when the\n lbs_ibss_join_existing function is called after a STA\n connects to an AP.(CVE-2019-14896)A stack-based buffer\n overflow was found in the Linux kernel, version\n kernel-2.6.32, in Marvell WiFi chip driver. An attacker\n is able to cause a denial of service (system crash) or,\n possibly execute arbitrary code, when a STA works in\n IBSS mode (allows connecting stations together without\n the use of an AP) and connects to another\n STA.(CVE-2019-14897)In the Linux kernel through 5.4.6,\n there is a NULL pointer dereference in\n drivers/scsi/libsas/sas_discover.c because of\n mishandling of port disconnection during discovery,\n related to a PHY down race condition, aka\n CID-f70267f379b5.(CVE-2019-19965)In the Linux kernel\n before 5.1.6, there is a use-after-free in cpia2_exit()\n in drivers/media/usb/cpia2/cpia2_v4l.c that will cause\n denial of service, aka\n CID-dea37a972655.(CVE-2019-19966)In the Linux kernel\n before 5.1, there is a memory leak in\n __feat_register_sp() in net/dccp/feat.c, which may\n cause denial of service, aka\n CID-1d3ff0950e2b.(CVE-2019-20096)In the Linux kernel\n before 5.0.6, there is a NULL pointer dereference in\n drop_sysctl_table() in fs/proc/proc_sysctl.c, related\n to put_links, aka\n CID-23da9588037e.(CVE-2019-20054)drivers/\n net/usb/pegasus.c in the Linux kernel 4.9.x before\n 4.9.11 interacts incorrectly with the CONFIG_VMAP_STACK\n option, which allows local users to cause a denial of\n service (system crash or memory corruption) or possibly\n have unspecified other impact by leveraging use of more\n than one virtual page for a DMA\n scatterlist.(CVE-2017-8068)A heap-based buffer overflow\n was discovered in the Linux kernel, all versions 3.x.x\n and 4.x.x before 4.18.0, in Marvell WiFi chip driver.\n The flaw could occur when the station attempts a\n connection negotiation during the handling of the\n remote devices country settings. This could allow the\n remote device to cause a denial of service (system\n crash) or possibly execute arbitrary\n code.(CVE-2019-14895)The acpi_ds_create_operands()\n function in drivers/acpi/acpica/dsutils.c in the Linux\n kernel through 4.12.9 does not flush the operand cache\n and causes a kernel stack dump, which allows local\n users to obtain sensitive information from kernel\n memory and bypass the KASLR protection mechanism (in\n the kernel through 4.9) via a crafted ACPI\n table.(CVE-2017-13693)Linux kernel CIFS implementation,\n version 4.9.0 is vulnerable to a relative paths\n injection in directory entry lists.(CVE-2019-10220)A\n heap overflow flaw was found in the Linux kernel, all\n versions 3.x.x and 4.x.x before 4.18.0, in Marvell WiFi\n chip driver. The vulnerability allows a remote attacker\n to cause a system crash, resulting in a denial of\n service, or execute arbitrary code. The highest threat\n with this vulnerability is with the availability of the\n system. If code execution occurs, the code will run\n with the permissions of root. This will affect both\n confidentiality and integrity of files on the\n system.(CVE-2019-14901)In the AppleTalk subsystem in\n the Linux kernel before 5.1, there is a potential NULL\n pointer dereference because register_snap_client may\n return NULL. This will lead to denial of service in\n net/appletalk/aarp.c and net/appletalk/ddp.c, as\n demonstrated by unregister_snap_client, aka\n CID-9804501fa122.(CVE-2019-19227)In the Linux kernel\n before 5.2.10, there is a use-after-free bug that can\n be caused by a malicious USB device in the\n drivers/usb/class/cdc-acm.c driver, aka\n CID-c52873e5a1ef.(CVE-2019-19530)In the Linux kernel\n before 5.3.9, there are multiple out-of-bounds write\n bugs that can be caused by a malicious USB device in\n the Linux kernel HID drivers, aka CID-d9d4b1e46d95.\n This affects drivers/hid/hid-axff.c,\n drivers/hid/hid-dr.c, drivers/hid/hid-emsff.c,\n drivers/hid/hid-gaff.c, drivers/hid/hid-holtekff.c,\n drivers/hid/hid-lg2ff.c, drivers/hid/hid-lg3ff.c,\n drivers/hid/hid-lg4ff.c, drivers/hid/hid-lgff.c,\n drivers/hid/hid-logitech-hidpp.c,\n drivers/hid/hid-microsoft.c, drivers/hid/hid-sony.c,\n drivers/hid/hid-tmff.c, and\n drivers/hid/hid-zpff.c.(CVE-2019-19532)A use-after-free\n in binder.c allows an elevation of privilege from an\n application to the Linux Kernel. No user interaction is\n required to exploit this vulnerability, however\n exploitation does require either the installation of a\n malicious local application or a separate vulnerability\n in a network facing application.Product: AndroidAndroid\n ID: A-141720095(CVE-2019-2215)The do_remount function\n in fs/ namespace.c in the Linux kernel through 3.16.1\n does not maintain the MNT_LOCK_READONLY bit across a\n remount of a bind mount, which allows local users to\n bypass an intended read-only restriction and defeat\n certain sandbox protection mechanisms via a 'mount -o\n remount' command within a user\n namespace.(CVE-2014-5206)Multiple integer overflows in\n the lzo1x_decompress_safe function in\n lib/lzo/lzo1x_decompress_safe.c in the LZO decompressor\n in the Linux kernel before 3.15.2 allow\n context-dependent attackers to cause a denial of\n service (memory corruption) via a crafted Literal Run.\n NOTE: the author of the LZO algorithms says 'the Linux\n kernel is *not* affected media hype.'(CVE-2014-4608)The\n pivot_root implementation in fs/ namespace.c in the\n Linux kernel through 3.17 does not properly interact\n with certain locations of a chroot directory, which\n allows local users to cause a denial of service\n (mount-tree loop) via . (dot) values in both arguments\n to the pivot_root system call.(CVE-2014-7970)A security\n flaw was discovered in nl80211_set_rekey_data()\n function in the Linux kernel since v3.1-rc1 through\n v4.13. This function does not check whether the\n required attributes are present in a netlink request.\n This request can be issued by a user with CAP_NET_ADMIN\n privilege and may result in NULL

"description": "The version of AOS installed on the remote host is prior to 5.19.0.5. It is, therefore, affected by multiple vulnerabilities as referenced in the NXSA-AOS-5.19.0.5 advisory.\n\n - libpng before 1.6.32 does not properly check the length of chunks against the user limit. (CVE-2017-12652)\n\n - In Apache httpd 2.4.0 to 2.4.29, the expression specified in <FilesMatch> could match '$' to a newline character in a malicious filename, rather than matching only the end of the filename. This could be exploited in environments where uploads of some files are are externally blocked, but only by matching the trailing portion of the filename. (CVE-2017-15715)\n\n - A localhost.localdomain whitelist entry in valid_host() in scheduler/client.c in CUPS before 2.2.2 allows remote attackers to execute arbitrary IPP commands by sending POST requests to the CUPS daemon in conjunction with DNS rebinding. The localhost.localdomain name is often resolved via a DNS server (neither the OS nor the web browser is responsible for ensuring that localhost.localdomain is 127.0.0.1).\n (CVE-2017-18190)\n\n - An issue was discovered in drivers/i2c/i2c-core-smbus.c in the Linux kernel before 4.14.15. There is an out of bounds write in the function i2c_smbus_xfer_emulated. (CVE-2017-18551)\n\n - The default cloud-init configuration, in cloud-init 0.6.2 and newer, included ssh_deletekeys: 0, disabling cloud-init's deletion of ssh host keys. In some environments, this could lead to instances created by cloning a golden master or template system, sharing ssh host keys, and being able to impersonate one another or conduct man-in-the-middle attacks. (CVE-2018-10896)\n\n - In Apache httpd 2.4.0 to 2.4.29, when mod_session is configured to forward its session data to CGI applications (SessionEnv on, not the default), a remote user may influence their content by using a Session header. This comes from the HTTP_SESSION variable name used by mod_session to forward its data to CGIs, since the prefix HTTP_ is also used by the Apache HTTP Server to pass HTTP header fields, per CGI specifications. (CVE-2018-1283)\n\n - A specially crafted HTTP request header could have crashed the Apache HTTP Server prior to version 2.4.30 due to an out of bound read while preparing data to be cached in shared memory. It could be used as a Denial of Service attack against users of mod_cache_socache. The vulnerability is considered as low risk since mod_cache_socache is not widely used, mod_cache_disk is not concerned by this vulnerability.\n (CVE-2018-1303)\n\n - An issue was discovered in the Linux kernel before 4.20. There is a race condition in smp_task_timedout() and smp_task_done() in drivers/scsi/libsas/sas_expander.c, leading to a use-after-free. (CVE-2018-20836)\n\n - In libexpat in Expat before 2.2.7, XML input including XML names that contain a large number of colons could make the XML parser consume a high amount of RAM and CPU resources while processing (enough to be usable for denial-of-service attacks). (CVE-2018-20843)\n\n - In Apache HTTP server 2.4.0 to 2.4.39, Redirects configured with mod_rewrite that were intended to be self-referential might be fooled by encoded newlines and redirect instead to an unexpected URL within the request URL. (CVE-2019-10098)\n\n - libmspack 0.9.1alpha is affected by: Buffer Overflow. The impact is: Information Disclosure. The component is: function chmd_read_headers() in libmspack(file libmspack/mspack/chmd.c). The attack vector is: the victim must open a specially crafted chm file. The fixed version is: after commit 2f084136cfe0d05e5bf5703f3e83c6d955234b4d. (CVE-2019-1010305)\n\n - libxslt through 1.1.33 allows bypass of a protection mechanism because callers of xsltCheckRead and xsltCheckWrite permit access even upon receiving a -1 error code. xsltCheckRead can return -1 for a crafted URL that is not actually invalid and is subsequently loaded. (CVE-2019-11068)\n\n - When importing a curve25519 private key in PKCS#8format with leading 0x00 bytes, it is possible to trigger an out-of-bounds read in the Network Security Services (NSS) library. This could lead to information disclosure. This vulnerability affects Firefox ESR < 60.8, Firefox < 68, and Thunderbird < 60.8.\n (CVE-2019-11719)\n\n - A vulnerability exists where it possible to force Network Security Services (NSS) to sign CertificateVerify with PKCS#1 v1.5 signatures when those are the only ones advertised by server in CertificateRequest in TLS 1.3. PKCS#1 v1.5 signatures should not be used for TLS 1.3 messages. This vulnerability affects Firefox < 68. (CVE-2019-11727)\n\n - Improper refcounting of soft token session objects could cause a use-after-free and crash (likely limited to a denial of service). This vulnerability affects Firefox < 71. (CVE-2019-11756)\n\n - file_copy_fallback in gio/gfile.c in GNOME GLib 2.15.0 through 2.61.1 does not properly restrict file permissions while a copy operation is in progress. Instead, default permissions are used. (CVE-2019-12450)\n\n - An issue was discovered in dlpar_parse_cc_property in arch/powerpc/platforms/pseries/dlpar.c in the Linux kernel through 5.1.6. There is an unchecked kstrdup of prop->name, which might allow an attacker to cause a denial of service (NULL pointer dereference and system crash). (CVE-2019-12614)\n\n - dbus before 1.10.28, 1.12.x before 1.12.16, and 1.13.x before 1.13.12, as used in DBusServer in Canonical Upstart in Ubuntu 14.04 (and in some, less common, uses of dbus-daemon), allows cookie spoofing because of symlink mishandling in the reference implementation of DBUS_COOKIE_SHA1 in the libdbus library. (This only affects the DBUS_COOKIE_SHA1 authentication mechanism.) A malicious client with write access to its own home directory could manipulate a ~/.dbus-keyrings symlink to cause a DBusServer with a different uid to read and write in unintended locations. In the worst case, this could result in the DBusServer reusing a cookie that is known to the malicious client, and treating that cookie as evidence that a subsequent client connection came from an attacker-chosen uid, allowing authentication bypass. (CVE-2019-12749)\n\n - A flaw was discovered in ibus in versions before 1.5.22 that allows any unprivileged user to monitor and send method calls to the ibus bus of another user due to a misconfiguration in the DBus server setup. A local attacker may use this flaw to intercept all keystrokes of a victim user who is using the graphical interface, change the input method engine, or modify other input related configurations of the victim user. (CVE-2019-14822)\n\n - In all versions of cpio before 2.13 does not properly validate input files when generating TAR archives.\n When cpio is used to create TAR archives from paths an attacker can write to, the resulting archive may contain files with permissions the attacker did not have or in paths he did not have access to. Extracting those archives from a high-privilege user without carefully reviewing them may lead to the compromise of the system. (CVE-2019-14866)\n\n - An issue was discovered in the Linux kernel before 5.2.3. There is a NULL pointer dereference caused by a malicious USB device in the drivers/media/usb/zr364xx/zr364xx.c driver. (CVE-2019-15217)\n\n - In the Linux kernel before 5.1.13, there is a memory leak in drivers/scsi/libsas/sas_expander.c when SAS expander discovery fails. This will cause a BUG and denial of service. (CVE-2019-15807)\n\n - In libexpat before 2.2.8, crafted XML input could fool the parser into changing from DTD parsing to document parsing too early; a consecutive call to XML_GetCurrentLineNumber (or XML_GetCurrentColumnNumber) then resulted in a heap-based buffer over-read. (CVE-2019-15903)\n\n - An issue was discovered in the Linux kernel before 5.0.5. There is a use-after-free issue when hci_uart_register_dev() fails in hci_uart_set_proto() in drivers/bluetooth/hci_ldisc.c. (CVE-2019-15917)\n\n - drivers/net/fjes/fjes_main.c in the Linux kernel 5.2.14 does not check the alloc_workqueue return value, leading to a NULL pointer dereference.

(CVE-2020-14305)\n\n - A flaw was found in the Linux kernel's implementation of the invert video code on VGA consoles when a local attacker attempts to resize the console, calling an ioctl VT_RESIZE, which causes an out-of-bounds write to occur. This flaw allows a local user with access to the VGA console to crash the system, potentially escalating their privileges on the system. The highest threat from this vulnerability is to data confidentiality and integrity as well as system availability. (CVE-2020-14331)\n\n - Lib/ipaddress.py in Python through 3.8.3 improperly computes hash values in the IPv4Interface and IPv6Interface classes, which might allow a remote attacker to cause a denial of service if an application is affected by the performance of a dictionary containing IPv4Interface or IPv6Interface objects, and this attacker can cause many dictionary entries to be created. This is fixed in: v3.5.10, v3.5.10rc1; v3.6.12;\n v3.7.9; v3.8.4, v3.8.4rc1, v3.8.5, v3.8.6, v3.8.6rc1; v3.9.0, v3.9.0b4, v3.9.0b5, v3.9.0rc1, v3.9.0rc2.\n (CVE-2020-14422)\n\n - Heap buffer overflow in Freetype in Google Chrome prior to 86.0.4240.111 allowed a remote attacker to potentially exploit heap corruption via a crafted HTML page. (CVE-2020-15999)\n\n - A flaw was found in the Linux kernel's implementation of some networking protocols in IPsec, such as VXLAN and GENEVE tunnels over IPv6. When an encrypted tunnel is created between two hosts, the kernel isn't correctly routing tunneled data over the encrypted link; rather sending the data unencrypted. This would allow anyone in between the two endpoints to read the traffic unencrypted. The main threat from this vulnerability is to data confidentiality. (CVE-2020-1749)\n\n - While investigating bug 64830 it was discovered that Apache Tomcat 10.0.0-M1 to 10.0.0-M9, 9.0.0-M1 to 9.0.39 and 8.5.0 to 8.5.59 could re-use an HTTP request header value from the previous stream received on an HTTP/2 connection for the request associated with the subsequent stream. While this would most likely lead to an error and the closure of the HTTP/2 connection, it is possible that information could leak between requests. (CVE-2020-17527)\n\n - In Apache HTTP Server 2.4.0 to 2.4.41, redirects configured with mod_rewrite that were intended to be self-referential might be fooled by encoded newlines and redirect instead to an an unexpected URL within the request URL.

It is, therefore, affected by multiple\nvulnerabilities as referenced in the NXSA-AOS-5.19.0.5 advisory.\n\n - libpng before 1.6.32 does not properly check the length of chunks against the user limit. (CVE-2017-12652)\n\n - In Apache httpd 2.4.0 to 2.4.29, the expression specified in <FilesMatch> could match '$' to a newline\n character in a malicious filename, rather than matching only the end of the filename. This could be\n exploited in environments where uploads of some files are are externally blocked, but only by matching the\n trailing portion of the filename. (CVE-2017-15715)\n\n - A localhost.localdomain whitelist entry in valid_host() in scheduler/client.c in CUPS before 2.2.2 allows\n remote attackers to execute arbitrary IPP commands by sending POST requests to the CUPS daemon in\n conjunction with DNS rebinding. The localhost.localdomain name is often resolved via a DNS server (neither\n the OS nor the web browser is responsible for ensuring that localhost.localdomain is 127.0.0.1).\n (CVE-2017-18190)\n\n - An issue was discovered in drivers/i2c/i2c-core-smbus.c in the Linux kernel before 4.14.15. There is an\n out of bounds write in the function i2c_smbus_xfer_emulated. (CVE-2017-18551)\n\n - The default cloud-init configuration, in cloud-init 0.6.2 and newer, included ssh_deletekeys: 0,\n disabling cloud-init's deletion of ssh host keys. In some environments, this could lead to instances\n created by cloning a golden master or template system, sharing ssh host keys, and being able to\n impersonate one another or conduct man-in-the-middle attacks. (CVE-2018-10896)\n\n - In Apache httpd 2.4.0 to 2.4.29, when mod_session is configured to forward its session data to CGI\n applications (SessionEnv on, not the default), a remote user may influence their content by using a\n Session header. This comes from the HTTP_SESSION variable name used by mod_session to forward its data\n to CGIs, since the prefix HTTP_ is also used by the Apache HTTP Server to pass HTTP header fields, per\n CGI specifications. (CVE-2018-1283)\n\n - A specially crafted HTTP request header could have crashed the Apache HTTP Server prior to version 2.4.30\n due to an out of bound read while preparing data to be cached in shared memory. It could be used as a\n Denial of Service attack against users of mod_cache_socache. The vulnerability is considered as low risk\n since mod_cache_socache is not widely used, mod_cache_disk is not concerned by this vulnerability.\n (CVE-2018-1303)\n\n - An issue was discovered in the Linux kernel before 4.20. There is a race condition in smp_task_timedout()\n and smp_task_done() in drivers/scsi/libsas/sas_expander.c, leading to a use-after-free. (CVE-2018-20836)\n\n - In libexpat in Expat before 2.2.7, XML input including XML names that contain a large number of colons\n could make the XML parser consume a high amount of RAM and CPU resources while processing (enough to be\n usable for denial-of-service attacks). (CVE-2018-20843)\n\n - In Apache HTTP server 2.4.0 to 2.4.39, Redirects configured with mod_rewrite that were intended to be\n self-referential might be fooled by encoded newlines and redirect instead to an unexpected URL within the\n request URL. (CVE-2019-10098)\n\n - libmspack 0.9.1alpha is affected by: Buffer Overflow. The impact is: Information Disclosure. The component\n is: function chmd_read_headers() in libmspack(file libmspack/mspack/chmd.c). The attack vector is: the\n victim must open a specially crafted chm file. The fixed version is: after commit\n 2f084136cfe0d05e5bf5703f3e83c6d955234b4d. (CVE-2019-1010305)\n\n - libxslt through 1.1.33 allows bypass of a protection mechanism because callers of xsltCheckRead and\n xsltCheckWrite permit access even upon receiving a -1 error code. xsltCheckRead can return -1 for a\n crafted URL that is not actually invalid and is subsequently loaded. (CVE-2019-11068)\n\n - When importing a curve25519 private key in PKCS#8format with leading 0x00 bytes, it is possible to trigger\n an out-of-bounds read in the Network Security Services (NSS) library. This could lead to information\n disclosure. This vulnerability affects Firefox ESR < 60.8, Firefox < 68, and Thunderbird < 60.8.\n (CVE-2019-11719)\n\n - A vulnerability exists where it possible to force Network Security Services (NSS) to sign\n CertificateVerify with PKCS#1 v1.5 signatures when those are the only ones advertised by server in\n CertificateRequest in TLS 1.3. PKCS#1 v1.5 signatures should not be used for TLS 1.3 messages. This\n vulnerability affects Firefox < 68. (CVE-2019-11727)\n\n - Improper refcounting of soft token session objects could cause a use-after-free and crash (likely limited\n to a denial of service). This vulnerability affects Firefox < 71. (CVE-2019-11756)\n\n - file_copy_fallback in gio/gfile.c in GNOME GLib 2.15.0 through 2.61.1 does not properly restrict file\n permissions while a copy operation is in progress. Instead, default permissions are used. (CVE-2019-12450)\n\n - An issue was discovered in dlpar_parse_cc_property in arch/powerpc/platforms/pseries/dlpar.c in the Linux\n kernel through 5.1.6. There is an unchecked kstrdup of prop->name, which might allow an attacker to cause\n a denial of service (NULL pointer dereference and system crash). (CVE-2019-12614)\n\n - dbus before 1.10.28, 1.12.x before 1.12.16, and 1.13.x before 1.13.12, as used in DBusServer in Canonical\n Upstart in Ubuntu 14.04 (and in some, less common, uses of dbus-daemon), allows cookie spoofing because of\n symlink mishandling in the reference implementation of DBUS_COOKIE_SHA1 in the libdbus library. (This only\n affects the DBUS_COOKIE_SHA1 authentication mechanism.) A malicious client with write access to its own\n home directory could manipulate a ~/.dbus-keyrings symlink to cause a DBusServer with a different uid to\n read and write in unintended locations. In the worst case, this could result in the DBusServer reusing a\n cookie that is known to the malicious client, and treating that cookie as evidence that a subsequent\n client connection came from an attacker-chosen uid, allowing authentication bypass. (CVE-2019-12749)\n\n - A flaw was discovered in ibus in versions before 1.5.22 that allows any unprivileged user to monitor and\n send method calls to the ibus bus of another user due to a misconfiguration in the DBus server setup. A\n local attacker may use this flaw to intercept all keystrokes of a victim user who is using the graphical\n interface, change the input method engine, or modify other input related configurations of the victim\n user. (CVE-2019-14822)\n\n - In all versions of cpio before 2.13 does not properly validate input files when generating TAR archives.\n When cpio is used to create TAR archives from paths an attacker can write to, the resulting archive may\n contain files with permissions the attacker did not have or in paths he did not have access to. Extracting\n those archives from a high-privilege user without carefully reviewing them may lead to the compromise of\n the system. (CVE-2019-14866)\n\n - An issue was discovered in the Linux kernel before 5.2.3. There is a NULL pointer dereference caused by a\n malicious USB device in the drivers/media/usb/zr364xx/zr364xx.c driver. (CVE-2019-15217)\n\n - In the Linux kernel before 5.1.13, there is a memory leak in drivers/scsi/libsas/sas_expander.c when SAS\n expander discovery fails. This will cause a BUG and denial of service. (CVE-2019-15807)\n\n - In libexpat before 2.2.8, crafted XML input could fool the parser into changing from DTD parsing to\n document parsing too early; a consecutive call to XML_GetCurrentLineNumber (or XML_GetCurrentColumnNumber)\n then resulted in a heap-based buffer over-read. (CVE-2019-15903)\n\n - An issue was discovered in the Linux kernel before 5.0.5. There is a use-after-free issue when\n hci_uart_register_dev() fails in hci_uart_set_proto() in drivers/bluetooth/hci_ldisc.c. (CVE-2019-15917)\n\n - drivers/net/fjes/fjes_main.c in the Linux kernel 5.2.14 does not check the alloc_workqueue return value,\n leading to a NULL pointer dereference. (CVE-2019-16231)\n\n - drivers/scsi/qla2xxx/qla_os.c in the Linux kernel 5.2.14 does not check the alloc_workqueue return value,\n leading to a NULL pointer dereference. (CVE-2019-16233)\n\n - The documentation XML-RPC server in Python through 2.7.16, 3.x through 3.6.9, and 3.7.x through 3.7.4 has\n XSS via the server_title field. This occurs in Lib/DocXMLRPCServer.py in Python 2.x, and in\n Lib/xmlrpc/server.py in Python 3.x. If set_server_title is called with untrusted input, arbitrary\n JavaScript can be delivered to clients that visit the http URL for this server. (CVE-2019-16935)\n\n - In the Linux kernel before 5.0, a memory leak exists in sit_init_net() in net/ipv6/sit.c when\n register_netdev() fails to register sitn->fb_tunnel_dev, which may cause denial of service, aka\n CID-07f12b26e21a. (CVE-2019-16994)\n\n - In Network Security Services (NSS) before 3.46, several cryptographic primitives had missing length\n checks. In cases where the application calling the library did not perform a sanity check on the inputs it\n could result in a crash due to a buffer overflow. (CVE-2019-17006)\n\n - After a HelloRetryRequest has been sent, the client may negotiate a lower protocol that TLS 1.3, resulting\n in an invalid state transition in the TLS State Machine. If the client gets into this state, incoming\n Application Data records will be ignored. This vulnerability affects Firefox < 72. (CVE-2019-17023)\n\n - ieee802154_create in net/ieee802154/socket.c in the AF_IEEE802154 network module in the Linux kernel\n through 5.3.2 does not enforce CAP_NET_RAW, which means that unprivileged users can create a raw socket,\n aka CID-e69dbd4619e7. (CVE-2019-17053)\n\n - base_sock_create in drivers/isdn/mISDN/socket.c in the AF_ISDN network module in the Linux kernel through\n 5.3.2 does not enforce CAP_NET_RAW, which means that unprivileged users can create a raw socket, aka\n CID-b91ee4aa2a21. (CVE-2019-17055)\n\n - In libssh2 v1.9.0 and earlier versions, the SSH_MSG_DISCONNECT logic in packet.c has an integer overflow\n in a bounds check, enabling an attacker to specify an arbitrary (out-of-bounds) offset for a subsequent\n memory read. A crafted SSH server may be able to disclose sensitive information or cause a denial of\n service condition on the client system when a user connects to the server. (CVE-2019-17498)\n\n - In xsltCopyText in transform.c in libxslt 1.1.33, a pointer variable isn't reset under certain\n circumstances. If the relevant memory area happened to be freed and reused in a certain way, a bounds\n check could fail and memory outside a buffer could be written to, or uninitialized data could be\n disclosed. (CVE-2019-18197)\n\n - A memory leak in the ccp_run_sha_cmd() function in drivers/crypto/ccp/ccp-ops.c in the Linux kernel\n through 5.3.9 allows attackers to cause a denial of service (memory consumption), aka CID-128c66429247.\n (CVE-2019-18808)\n\n - ** DISPUTED ** A memory leak in the __ipmi_bmc_register() function in drivers/char/ipmi/ipmi_msghandler.c\n in the Linux kernel through 5.3.11 allows attackers to cause a denial of service (memory consumption) by\n triggering ida_simple_get() failure, aka CID-4aa7afb0ee20. NOTE: third parties dispute the relevance of\n this because an attacker cannot realistically control this failure at probe time. (CVE-2019-19046)\n\n - ** DISPUTED ** A memory leak in the nl80211_get_ftm_responder_stats() function in net/wireless/nl80211.c\n in the Linux kernel through 5.3.11 allows attackers to cause a denial of service (memory consumption) by\n triggering nl80211hdr_put() failures, aka CID-1399c59fa929. NOTE: third parties dispute the relevance of\n this because it occurs on a code path where a successful allocation has already occurred. (CVE-2019-19055)\n\n - A memory leak in the alloc_sgtable() function in drivers/net/wireless/intel/iwlwifi/fw/dbg.c in the Linux\n kernel through 5.3.11 allows attackers to cause a denial of service (memory consumption) by triggering\n alloc_page() failures, aka CID-b4b814fec1a5. (CVE-2019-19058)\n\n - Multiple memory leaks in the iwl_pcie_ctxt_info_gen3_init() function in\n drivers/net/wireless/intel/iwlwifi/pcie/ctxt-info-gen3.c in the Linux kernel through 5.3.11 allow\n attackers to cause a denial of service (memory consumption) by triggering iwl_pcie_init_fw_sec() or\n dma_alloc_coherent() failures, aka CID-0f4f199443fa. (CVE-2019-19059)\n\n - A memory leak in the crypto_report() function in crypto/crypto_user_base.c in the Linux kernel through\n 5.3.11 allows attackers to cause a denial of service (memory consumption) by triggering\n crypto_report_alg() failures, aka CID-ffdde5932042. (CVE-2019-19062)\n\n - Two memory leaks in the rtl_usb_probe() function in drivers/net/wireless/realtek/rtlwifi/usb.c in the\n Linux kernel through 5.3.11 allow attackers to cause a denial of service (memory consumption), aka\n CID-3f9361695113. (CVE-2019-19063)\n\n - On the x86-64 architecture, the GNU C Library (aka glibc) before 2.31 fails to ignore the\n LD_PREFER_MAP_32BIT_EXEC environment variable during program execution after a security transition,\n allowing local attackers to restrict the possible mapping addresses for loaded libraries and thus bypass\n ASLR for a setuid program. (CVE-2019-19126)\n\n - An out-of-bounds memory write issue was found in the Linux Kernel, version 3.13 through 5.4, in the way\n the Linux kernel's KVM hypervisor handled the 'KVM_GET_EMULATED_CPUID' ioctl(2) request to get CPUID\n features emulated by the KVM hypervisor. A user or process able to access the '/dev/kvm' device could use\n this flaw to crash the system, resulting in a denial of service.

(CVE-2019-9454)\n\n - In the Android kernel in the video driver there is a use after free due to a race condition. This could\n lead to local escalation of privilege with no additional execution privileges needed. User interaction is\n not needed for exploitation. (CVE-2019-9458)\n\n - There is a use-after-free in kernel versions before 5.5 due to a race condition between the release of\n ptp_clock and cdev while resource deallocation. When a (high privileged) process allocates a ptp device\n file (like /dev/ptpX) and voluntarily goes to sleep. During this time if the underlying device is removed,\n it can cause an exploitable condition as the process wakes up to terminate and clean all attached files.\n The system crashes due to the cdev structure being invalid (as already freed) which is pointed to by the\n inode. (CVE-2020-10690)\n\n - A flaw was found in the Linux kernel's implementation of Userspace core dumps. This flaw allows an\n attacker with a local account to crash a trivial program and exfiltrate private kernel data.\n (CVE-2020-10732)\n\n - A flaw was found in the Linux kernel. An index buffer overflow during Direct IO write leading to the NFS\n client to crash. In some cases, a reach out of the index after one memory allocation by kmalloc will cause\n a kernel panic. The highest threat from this vulnerability is to data confidentiality and system\n availability. (CVE-2020-10742)\n\n - A flaw was found in the Linux kernels SELinux LSM hook implementation before version 5.7, where it\n incorrectly assumed that an skb would only contain a single netlink message. The hook would incorrectly\n only validate the first netlink message in the skb and allow or deny the rest of the messages within the\n skb with the granted permission without further processing. (CVE-2020-10751)\n\n - In the Linux kernel before 5.5.8, get_raw_socket in drivers/vhost/net.c lacks validation of an sk_family\n field, which might allow attackers to trigger kernel stack corruption via crafted system calls.\n (CVE-2020-10942)\n\n - ** DISPUTED ** An issue was discovered in the Linux kernel through 5.6.2. mpol_parse_str in mm/mempolicy.c\n has a stack-based out-of-bounds write because an empty nodelist is mishandled during mount option parsing,\n aka CID-aa9f7d5172fa. NOTE: Someone in the security community disagrees that this is a vulnerability\n because the issue is a bug in parsing mount options which can only be specified by a privileged user, so\n triggering the bug does not grant any powers not already held.. (CVE-2020-11565)\n\n - In filter.c in slapd in OpenLDAP before 2.4.50, LDAP search filters with nested boolean expressions can\n result in denial of service (daemon crash). (CVE-2020-12243)\n\n - When converting coordinates from projective to affine, the modular inversion was not performed in constant\n time, resulting in a possible timing-based side channel attack. This vulnerability affects Firefox < 80\n and Firefox for Android < 80. (CVE-2020-12400)\n\n - During ECDSA signature generation, padding applied in the nonce designed to ensure constant-time scalar\n multiplication was removed, resulting in variable-time execution dependent on secret data. This\n vulnerability affects Firefox < 80 and Firefox for Android < 80. (CVE-2020-12401)\n\n - During RSA key generation, bignum implementations used a variation of the Binary Extended Euclidean\n Algorithm which entailed significantly input-dependent flow. This allowed an attacker able to perform\n electromagnetic-based side channel attacks to record traces leading to the recovery of the secret primes.\n *Note:* An unmodified Firefox browser does not generate RSA keys in normal operation and is not affected,\n but products built on top of it might. This vulnerability affects Firefox < 78. (CVE-2020-12402)\n\n - A flaw was found in the way CHACHA20-POLY1305 was implemented in NSS in versions before 3.55. When using\n multi-part Chacha20, it could cause out-of-bounds reads. This issue was fixed by explicitly disabling\n multi-part ChaCha20 (which was not functioning correctly) and strictly enforcing tag length. The highest\n threat from this vulnerability is to confidentiality and system availability. (CVE-2020-12403)\n\n - An issue was discovered in the Linux kernel through 5.6.11. sg_write lacks an sg_remove_request call in a\n certain failure case, aka CID-83c6f2390040. (CVE-2020-12770)\n\n - A signal access-control issue was discovered in the Linux kernel before 5.6.5, aka CID-7395ea4e65c2.\n Because exec_id in include/linux/sched.h is only 32 bits, an integer overflow can interfere with a\n do_notify_parent protection mechanism. A child process can send an arbitrary signal to a parent process in\n a different security domain. Exploitation limitations include the amount of elapsed time before an integer\n overflow occurs, and the lack of scenarios where signals to a parent process present a substantial\n operational threat. (CVE-2020-12826)\n\n - If an HTTP/2 client connecting to Apache Tomcat 10.0.0-M1 to 10.0.0-M7, 9.0.0.M1 to 9.0.37 or 8.5.0 to\n 8.5.57 exceeded the agreed maximum number of concurrent streams for a connection (in violation of the\n HTTP/2 protocol), it was possible that a subsequent request made on that connection could contain HTTP\n headers - including HTTP/2 pseudo headers - from a previous request rather than the intended headers. This\n could lead to users seeing responses for unexpected resources. (CVE-2020-13943)\n\n - An out-of-bounds memory write flaw was found in how the Linux kernel's Voice Over IP H.323 connection\n tracking functionality handled connections on ipv6 port 1720. This flaw allows an unauthenticated remote\n user to crash the system, causing a denial of service. The highest threat from this vulnerability is to\n confidentiality, integrity, as well as system availability. (CVE-2020-14305)\n\n - A flaw was found in the Linux kernel's implementation of the invert video code on VGA consoles when a\n local attacker attempts to resize the console, calling an ioctl VT_RESIZE, which causes an out-of-bounds\n write to occur. This flaw allows a local user with access to the VGA console to crash the system,\n potentially escalating their privileges on the system. The highest threat from this vulnerability is to\n data confidentiality and integrity as well as system availability. (CVE-2020-14331)\n\n - Lib/ipaddress.py in Python through 3.8.3 improperly computes hash values in the IPv4Interface and\n IPv6Interface classes, which might allow a remote attacker to cause a denial of service if an application\n is affected by the performance of a dictionary containing IPv4Interface or IPv6Interface objects, and this\n attacker can cause many dictionary entries to be created. This is fixed in: v3.5.10, v3.5.10rc1; v3.6.12;\n v3.7.9; v3.8.4, v3.8.4rc1, v3.8.5, v3.8.6, v3.8.6rc1; v3.9.0, v3.9.0b4, v3.9.0b5, v3.9.0rc1, v3.9.0rc2.\n (CVE-2020-14422)\n\n - Heap buffer overflow in Freetype in Google Chrome prior to 86.0.4240.111 allowed a remote attacker to\n potentially exploit heap corruption via a crafted HTML page. (CVE-2020-15999)\n\n - A flaw was found in the Linux kernel's implementation of some networking protocols in IPsec, such as VXLAN\n and GENEVE tunnels over IPv6. When an encrypted tunnel is created between two hosts, the kernel isn't\n correctly routing tunneled data over the encrypted link; rather sending the data unencrypted. This would\n allow anyone in between the two endpoints to read the traffic unencrypted. The main threat from this\n vulnerability is to data confidentiality. (CVE-2020-1749)\n\n - While investigating bug 64830 it was discovered that Apache Tomcat 10.0.0-M1 to 10.0.0-M9, 9.0.0-M1 to\n 9.0.39 and 8.5.0 to 8.5.59 could re-use an HTTP request header value from the previous stream received on\n an HTTP/2 connection for the request associated with the subsequent stream. While this would most likely\n lead to an error and the closure of the HTTP/2 connection, it is possible that information could leak\n between requests. (CVE-2020-17527)\n\n - In Apache HTTP Server 2.4.0 to 2.4.41, redirects configured with mod_rewrite that were intended to be\n self-referential might be fooled by encoded newlines and redirect instead to an an unexpected URL within\n the request URL. (CVE-2020-1927)\n\n - In Apache HTTP Server 2.4.0 to 2.4.41, mod_proxy_ftp may use uninitialized memory when proxying to a\n malicious FTP server. (CVE-2020-1934)\n\n - Vulnerability in the MySQL Client product of Oracle MySQL (component: C API). Supported versions that are\n affected are 5.6.46 and prior, 5.7.28 and prior and 8.0.18 and prior. Difficult to exploit vulnerability\n allows unauthenticated attacker with network access via multiple protocols to compromise MySQL Client.\n Successful attacks of this vulnerability can result in unauthorized ability to cause a hang or frequently\n repeatable crash (complete DOS) of MySQL Client. (CVE-2020-2574)\n\n - A flaw was discovered in the way that the KVM hypervisor handled instruction emulation for an L2 guest\n when nested virtualisation is enabled. Under some circumstances, an L2 guest may trick the L0 guest into\n accessing sensitive L1 resources that should be inaccessible to the L2 guest. (CVE-2020-2732)\n\n - Vulnerability in the MySQL Client product of Oracle MySQL (component: C API). Supported versions that are\n affected are 5.6.47 and prior, 5.7.27 and prior and 8.0.17 and prior.

(CVE-2019-10098)\n\n - libmspack 0.9.1alpha is affected by: Buffer Overflow. The impact is: Information Disclosure. The component is: function chmd_read_headers() in libmspack(file libmspack/mspack/chmd.c). The attack vector is: the victim must open a specially crafted chm file. The fixed version is: after commit 2f084136cfe0d05e5bf5703f3e83c6d955234b4d. (CVE-2019-1010305)\n\n - libxslt through 1.1.33 allows bypass of a protection mechanism because callers of xsltCheckRead and xsltCheckWrite permit access even upon receiving a -1 error code. xsltCheckRead can return -1 for a crafted URL that is not actually invalid and is subsequently loaded. (CVE-2019-11068)\n\n - When importing a curve25519 private key in PKCS#8format with leading 0x00 bytes, it is possible to trigger an out-of-bounds read in the Network Security Services (NSS) library. This could lead to information disclosure. This vulnerability affects Firefox ESR < 60.8, Firefox < 68, and Thunderbird < 60.8.\n (CVE-2019-11719)\n\n - A vulnerability exists where it possible to force Network Security Services (NSS) to sign CertificateVerify with PKCS#1 v1.5 signatures when those are the only ones advertised by server in CertificateRequest in TLS 1.3. PKCS#1 v1.5 signatures should not be used for TLS 1.3 messages. This vulnerability affects Firefox < 68. (CVE-2019-11727)\n\n - Improper refcounting of soft token session objects could cause a use-after-free and crash (likely limited to a denial of service). This vulnerability affects Firefox < 71. (CVE-2019-11756)\n\n - file_copy_fallback in gio/gfile.c in GNOME GLib 2.15.0 through 2.61.1 does not properly restrict file permissions while a copy operation is in progress. Instead, default permissions are used. (CVE-2019-12450)\n\n - An issue was discovered in dlpar_parse_cc_property in arch/powerpc/platforms/pseries/dlpar.c in the Linux kernel through 5.1.6. There is an unchecked kstrdup of prop->name, which might allow an attacker to cause a denial of service (NULL pointer dereference and system crash). (CVE-2019-12614)\n\n - dbus before 1.10.28, 1.12.x before 1.12.16, and 1.13.x before 1.13.12, as used in DBusServer in Canonical Upstart in Ubuntu 14.04 (and in some, less common, uses of dbus-daemon), allows cookie spoofing because of symlink mishandling in the reference implementation of DBUS_COOKIE_SHA1 in the libdbus library. (This only affects the DBUS_COOKIE_SHA1 authentication mechanism.) A malicious client with write access to its own home directory could manipulate a ~/.dbus-keyrings symlink to cause a DBusServer with a different uid to read and write in unintended locations. In the worst case, this could result in the DBusServer reusing a cookie that is known to the malicious client, and treating that cookie as evidence that a subsequent client connection came from an attacker-chosen uid, allowing authentication bypass. (CVE-2019-12749)\n\n - A flaw was discovered in ibus in versions before 1.5.22 that allows any unprivileged user to monitor and send method calls to the ibus bus of another user due to a misconfiguration in the DBus server setup. A local attacker may use this flaw to intercept all keystrokes of a victim user who is using the graphical interface, change the input method engine, or modify other input related configurations of the victim user. (CVE-2019-14822)\n\n - In all versions of cpio before 2.13 does not properly validate input files when generating TAR archives.\n When cpio is used to create TAR archives from paths an attacker can write to, the resulting archive may contain files with permissions the attacker did not have or in paths he did not have access to. Extracting those archives from a high-privilege user without carefully reviewing them may lead to the compromise of the system. (CVE-2019-14866)\n\n - An issue was discovered in the Linux kernel before 5.2.3. There is a NULL pointer dereference caused by a malicious USB device in the drivers/media/usb/zr364xx/zr364xx.c driver. (CVE-2019-15217)\n\n - In the Linux kernel before 5.1.13, there is a memory leak in drivers/scsi/libsas/sas_expander.c when SAS expander discovery fails. This will cause a BUG and denial of service. (CVE-2019-15807)\n\n - In libexpat before 2.2.8, crafted XML input could fool the parser into changing from DTD parsing to document parsing too early; a consecutive call to XML_GetCurrentLineNumber (or XML_GetCurrentColumnNumber) then resulted in a heap-based buffer over-read. (CVE-2019-15903)\n\n - An issue was discovered in the Linux kernel before 5.0.5. There is a use-after-free issue when hci_uart_register_dev() fails in hci_uart_set_proto() in drivers/bluetooth/hci_ldisc.c. (CVE-2019-15917)\n\n - drivers/net/fjes/fjes_main.c in the Linux kernel 5.2.14 does not check the alloc_workqueue return value, leading to a NULL pointer dereference. (CVE-2019-16231)\n\n - drivers/scsi/qla2xxx/qla_os.c in the Linux kernel 5.2.14 does not check the alloc_workqueue return value, leading to a NULL pointer dereference. (CVE-2019-16233)\n\n - The documentation XML-RPC server in Python through 2.7.16, 3.x through 3.6.9, and 3.7.x through 3.7.4 has XSS via the server_title field. This occurs in Lib/DocXMLRPCServer.py in Python 2.x, and in Lib/xmlrpc/server.py in Python 3.x. If set_server_title is called with untrusted input, arbitrary JavaScript can be delivered to clients that visit the http URL for this server. (CVE-2019-16935)\n\n - In the Linux kernel before 5.0, a memory leak exists in sit_init_net() in net/ipv6/sit.c when register_netdev() fails to register sitn->fb_tunnel_dev, which may cause denial of service, aka CID-07f12b26e21a. (CVE-2019-16994)\n\n - In Network Security Services (NSS) before 3.46, several cryptographic primitives had missing length checks. In cases where the application calling the library did not perform a sanity check on the inputs it could result in a crash due to a buffer overflow. (CVE-2019-17006)\n\n - After a HelloRetryRequest has been sent, the client may negotiate a lower protocol that TLS 1.3, resulting in an invalid state transition in the TLS State Machine. If the client gets into this state, incoming Application Data records will be ignored. This vulnerability affects Firefox < 72. (CVE-2019-17023)\n\n - ieee802154_create in net/ieee802154/socket.c in the AF_IEEE802154 network module in the Linux kernel through 5.3.2 does not enforce CAP_NET_RAW, which means that unprivileged users can create a raw socket, aka CID-e69dbd4619e7. (CVE-2019-17053)\n\n - base_sock_create in drivers/isdn/mISDN/socket.c in the AF_ISDN network module in the Linux kernel through 5.3.2 does not enforce CAP_NET_RAW, which means that unprivileged users can create a raw socket, aka CID-b91ee4aa2a21. (CVE-2019-17055)\n\n - In libssh2 v1.9.0 and earlier versions, the SSH_MSG_DISCONNECT logic in packet.c has an integer overflow in a bounds check, enabling an attacker to specify an arbitrary (out-of-bounds) offset for a subsequent memory read. A crafted SSH server may be able to disclose sensitive information or cause a denial of service condition on the client system when a user connects to the server. (CVE-2019-17498)\n\n - In xsltCopyText in transform.c in libxslt 1.1.33, a pointer variable isn't reset under certain circumstances. If the relevant memory area happened to be freed and reused in a certain way, a bounds check could fail and memory outside a buffer could be written to, or uninitialized data could be disclosed. (CVE-2019-18197)\n\n - The flow_dissector feature in the Linux kernel 4.3 through 5.x before 5.3.10 has a device tracking vulnerability, aka CID-55667441c84f. This occurs because the auto flowlabel of a UDP IPv6 packet relies on a 32-bit hashrnd value as a secret, and because jhash (instead of siphash) is used. The hashrnd value remains the same starting from boot time, and can be inferred by an attacker. This affects net/core/flow_dissector.c and related code. (CVE-2019-18282)\n\n - A memory leak in the ccp_run_sha_cmd() function in drivers/crypto/ccp/ccp-ops.c in the Linux kernel through 5.3.9 allows attackers to cause a denial of service (memory consumption), aka CID-128c66429247.\n (CVE-2019-18808)\n\n - ** DISPUTED ** A memory leak in the __ipmi_bmc_register() function in drivers/char/ipmi/ipmi_msghandler.c in the Linux kernel through 5.3.11 allows attackers to cause a denial of service (memory consumption) by triggering ida_simple_get() failure, aka CID-4aa7afb0ee20. NOTE: third parties dispute the relevance of this because an attacker cannot realistically control this failure at probe time. (CVE-2019-19046)\n\n - ** DISPUTED ** A memory leak in the nl80211_get_ftm_responder_stats() function in net/wireless/nl80211.c in the Linux kernel through 5.3.11 allows attackers to cause a denial of service (memory consumption) by triggering nl80211hdr_put() failures, aka CID-1399c59fa929. NOTE: third parties dispute the relevance of this because it occurs on a code path where a successful allocation has already occurred. (CVE-2019-19055)\n\n - A memory leak in the alloc_sgtable() function in drivers/net/wireless/intel/iwlwifi/fw/dbg.c in the Linux kernel through 5.3.11 allows attackers to cause a denial of service (memory consumption) by triggering alloc_page() failures, aka CID-b4b814fec1a5. (CVE-2019-19058)\n\n - Multiple memory leaks in the iwl_pcie_ctxt_info_gen3_init() function in drivers/net/wireless/intel/iwlwifi/pcie/ctxt-info-gen3.c in the Linux kernel through 5.3.11 allow attackers to cause a denial of service (memory consumption) by triggering iwl_pcie_init_fw_sec() or dma_alloc_coherent() failures, aka CID-0f4f199443fa. (CVE-2019-19059)\n\n - A memory leak in the crypto_report() function in crypto/crypto_user_base.c in the Linux kernel through 5.3.11 allows attackers to cause a denial of service (memory consumption) by triggering crypto_report_alg() failures, aka CID-ffdde5932042. (CVE-2019-19062)\n\n - Two memory leaks in the rtl_usb_probe() function in drivers/net/wireless/realtek/rtlwifi/usb.c in the Linux kernel through 5.3.11 allow attackers to cause a denial of service (memory consumption), aka CID-3f9361695113. (CVE-2019-19063)\n\n - On the x86-64 architecture, the GNU C Library (aka glibc) before 2.31 fails to ignore the LD_PREFER_MAP_32BIT_EXEC environment variable during program execution after a security transition, allowing local attackers to restrict the possible mapping addresses for loaded libraries and thus bypass ASLR for a setuid program. (CVE-2019-19126)\n\n - An out-of-bounds memory write issue was found in the Linux Kernel, version 3.13 through 5.4, in the way the Linux kernel's KVM hypervisor handled the 'KVM_GET_EMULATED_CPUID' ioctl(2) request to get CPUID features emulated by the KVM hypervisor. A user or process able to access the '/dev/kvm' device could use this flaw to crash the system, resulting in a denial of service. (CVE-2019-19332)\n\n - In the Linux kernel 5.0.21, mounting a crafted ext4 filesystem image, performing some operations, and unmounting can lead to a use-after-free in ext4_put_super in fs/ext4/super.c, related to dump_orphan_list in fs/ext4/super.c. (CVE-2019-19447)\n\n - In the Linux kernel before 5.3.7, there is a use-after-free bug that can be caused by a malicious USB device in the drivers/usb/misc/adutux.c driver, aka CID-44efc269db79.
