The Linux kernel before 4.5 allows local users to bypass file-descriptor limits and cause a denial of service (memory consumption) by leveraging incorrect tracking of descriptor ownership and sending each descriptor over a UNIX socket before closing it. NOTE: this vulnerability exists because of an incorrect fix for CVE-2013-4312.

This is fixed by accounting queued files to\n the sender rather than the socket opener.\"\n );\n script_set_attribute(\n attribute:\"see_also\",\n value:\"https://security-tracker.debian.org/tracker/CVE-2013-4312\"\n );\n script_set_attribute(\n attribute:\"see_also\",\n value:\"https://security-tracker.debian.org/tracker/CVE-2016-2847\"\n );\n script_set_attribute(\n attribute:\"see_also\",\n value:\"https://security-tracker.debian.org/tracker/CVE-2015-7566\"\n );\n script_set_attribute(\n attribute:\"see_also\",\n value:\"https://security-tracker.debian.org/tracker/CVE-2015-8767\"\n );\n script_set_attribute(\n attribute:\"see_also\",\n value:\"https://security-tracker.debian.org/tracker/CVE-2015-8785\"\n );\n script_set_attribute(\n attribute:\"see_also\",\n value:\"https://security-tracker.debian.org/tracker/CVE-2015-8812\"\n );\n script_set_attribute(\n attribute:\"see_also\",\n value:\"https://security-tracker.debian.org/tracker/CVE-2015-8816\"\n );\n script_set_attribute(\n attribute:\"see_also\",\n value:\"https://security-tracker.debian.org/tracker/CVE-2015-8830\"\n );\n script_set_attribute(\n attribute:\"see_also\",\n value:\"https://security-tracker.debian.org/tracker/CVE-2016-0723\"\n );\n script_set_attribute(\n attribute:\"see_also\",\n value:\"https://security-tracker.debian.org/tracker/CVE-2016-0774\"\n );\n script_set_attribute(\n attribute:\"see_also\",\n value:\"https://security-tracker.debian.org/tracker/CVE-2015-1805\"\n );\n script_set_attribute(\n attribute:\"see_also\",\n value:\"https://security-tracker.debian.org/tracker/CVE-2016-2069\"\n );\n script_set_attribute(\n attribute:\"see_also\",\n value:\"https://security-tracker.debian.org/tracker/CVE-2016-2384\"\n );\n script_set_attribute(\n attribute:\"see_also\",\n value:\"https://security-tracker.debian.org/tracker/CVE-2016-2543\"\n );\n script_set_attribute(\n attribute:\"see_also\",\n value:\"https://security-tracker.debian.org/tracker/CVE-2016-2544\"\n );\n script_set_attribute(\n attribute:\"see_also\",\n value:\"https://security-tracker.debian.org/tracker/CVE-2016-2546\"\n );\n script_set_attribute(\n attribute:\"see_also\",\n value:\"https://security-tracker.debian.org/tracker/CVE-2016-2547\"\n );\n script_set_attribute(\n attribute:\"see_also\",\n value:\"https://security-tracker.debian.org/tracker/CVE-2016-2548\"\n );\n script_set_attribute(\n attribute:\"see_also\",\n value:\"https://security-tracker.debian.org/tracker/CVE-2016-2545\"\n );\n script_set_attribute(\n attribute:\"see_also\",\n value:\"https://security-tracker.debian.org/tracker/CVE-2016-2549\"\n );\n script_set_attribute(\n attribute:\"see_also\",\n value:\"https://security-tracker.debian.org/tracker/CVE-2016-2550\"\n );\n script_set_attribute(\n attribute:\"see_also\",\n value:\"https://security-tracker.debian.org/tracker/CVE-2013-4312\"\n );\n script_set_attribute(\n attribute:\"see_also\",\n value:\"https://security-tracker.debian.org/tracker/CVE-2015-8830\"\n );\n script_set_attribute(\n attribute:\"see_also\",\n value:\"https://security-tracker.debian.org/tracker/CVE-2013-4312\"\n );\n script_set_attribute(\n attribute:\"see_also\",\n value:\"https://security-tracker.debian.org/tracker/CVE-2015-7566\"\n );\n script_set_attribute(\n attribute:\"see_also\",\n value:\"https://security-tracker.debian.org/tracker/CVE-2015-8767\"\n );\n script_set_attribute(\n attribute:\"see_also\",\n value:\"https://security-tracker.debian.org/tracker/CVE-2016-0723\"\n );\n script_set_attribute(\n attribute:\"see_also\",\n value:\"https://security-tracker.debian.org/tracker/CVE-2016-0774\"\n );\n script_set_attribute(\n attribute:\"see_also\",\n value:\"https://packages.debian.org/source/jessie/linux\"\n );\n script_set_attribute(\n attribute:\"see_also\",\n value:\"https://www.debian.org/security/2016/dsa-3503\"\n );\n script_set_attribute(\n attribute:\"solution\", \n value:\n\"Upgrade the linux packages.\n\nFor the oldstable distribution (wheezy), these problems have been\nfixed in version 3.2.73-2+deb7u3.

packages installed, the EulerOS Virtualization for ARM 64 installation on the remote host is affected by the following vulnerabilities :\n\n - The offset2lib patch as used in the Linux Kernel contains a vulnerability that allows a PIE binary to be execve()'ed with 1GB of arguments or environmental strings then the stack occupies the address 0x80000000 and the PIE binary is mapped above 0x40000000 nullifying the protection of the offset2lib patch. This affects Linux Kernel version 4.11.5 and earlier. This is a different issue than CVE-2017-1000371. This issue appears to be limited to i386 based systems.(CVE-2017-1000370i1/4%0\n\n - Integer overflow in the LZ4 algorithm implementation, as used in Yann Collet LZ4 before r118 and in the lz4_uncompress function in lib/lz4/lz4_decompress.c in the Linux kernel before 3.15.2, on 32-bit platforms might allow context-dependent attackers to cause a denial of service (memory corruption) or possibly have unspecified other impact via a crafted Literal Run that would be improperly handled by programs not complying with an API limitation, a different vulnerability than CVE-2014-4715.(CVE-2014-4611i1/4%0\n\n - The replace_map_fd_with_map_ptr function in kernel/bpf/verifier.c in the Linux kernel before 4.5.5 does not properly maintain an fd data structure, which allows local users to gain privileges or cause a denial of service (use-after-free) via crafted BPF instructions that reference an incorrect file descriptor.(CVE-2016-4557i1/4%0\n\n - The usb_destroy_configuration() function, in 'drivers/usb/core/config.c' in the USB core subsystem, in the Linux kernel through 4.14.5 does not consider the maximum number of configurations and interfaces before attempting to release resources. This allows local users to cause a denial of service, due to out-of-bounds write access, or possibly have unspecified other impact via a crafted USB device. Due to the nature of the flaw, privilege escalation cannot be fully ruled out, although we believe it is unlikely.(CVE-2017-17558i1/4%0\n\n - The cdrom_ioctl_media_changed function in drivers/cdrom/cdrom.c in the Linux kernel before 4.16.6 allows local attackers to use a incorrect bounds check in the CDROM driver CDROM_MEDIA_CHANGED ioctl to read out kernel memory.(CVE-2018-10940i1/4%0\n\n - It was found that the parse_rock_ridge_inode_internal() function of the Linux kernel's ISOFS implementation did not correctly check relocated directories when processing Rock Ridge child link (CL) tags. An attacker with physical access to the system could use a specially crafted ISO image to crash the system or, potentially, escalate their privileges on the system.(CVE-2014-5471i1/4%0\n\n - A flaw was found in the Linux kernel's implementation of Unix sockets. A server polling for client-socket data could put the peer socket on a wait list the peer socket could then close the connection, making the reference on the wait list no longer valid. This could lead to bypassing the permissions on a Unix socket and packets being injected into the stream, and could also panic the machine (denial of service).(CVE-2013-7446i1/4%0\n\n - The do_check function in kernel/bpf/verifier.c in the Linux kernel before 4.11.1 does not make the allow_ptr_leaks value available for restricting the output of the print_bpf_insn function, which allows local users to obtain sensitive address information via crafted bpf system calls.(CVE-2017-9150i1/4%0\n\n - The WLAN (aka Wi-Fi) driver for the Linux kernel 3.x and 4.x, as used in Qualcomm Innovation Center (QuIC) Android contributions for MSM devices and other products, does not verify authorization for private SET IOCTL calls, which allows attackers to gain privileges via a crafted application, related to wlan_hdd_hostapd.c and wlan_hdd_wext.c.(CVE-2015-0571i1/4%0\n\n - arch/arm64/kvm/guest.c in KVM in the Linux kernel before 4.18.12 on the arm64 platform mishandles the KVM_SET_ON_REG ioctl. This is exploitable by attackers who can create virtual machines. An attacker can arbitrarily redirect the hypervisor flow of control (with full register control). An attacker can also cause a denial of service (hypervisor panic) via an illegal exception return. This occurs because of insufficient restrictions on userspace access to the core register file, and because PSTATE.M validation does not prevent unintended execution modes.(CVE-2018-18021i1/4%0\n\n - A resource-exhaustion vulnerability was found in the kernel, where an unprivileged process could allocate and accumulate far more file descriptors than the process' limit. A local, unauthenticated user could exploit this flaw by sending file descriptors over a Unix socket and then closing them to keep the process' fd count low, thereby creating kernel-memory or file-descriptors exhaustion (denial of service).(CVE-2016-2550i1/4%0\n\n - The Linux kernel before 3.12.4 updates certain length values before ensuring that associated data structures have been initialized, which allows local users to obtain sensitive information from kernel stack memory via a (1) recvfrom, (2) recvmmsg, or (3) recvmsg system call, related to net/ipv4/ping.c, net/ipv4/raw.c, net/ipv4/udp.c, net/ipv6/raw.c, and net/ipv6/udp.c.(CVE-2013-7263i1/4%0\n\n - It is possible for a single process to cause an OOM condition by filling large pipes with data that are never read. A typical process filling 4096 pipes with 1 MB of data will use 4 GB of memory and there can be multiple such processes, up to a per-user-limit.(CVE-2016-2847i1/4%0\n\n - The __get_user_asm_ex macro in arch/x86/include/asm/uaccess.h in the Linux kernel before 4.7.5 does not initialize a certain integer variable, which allows local users to obtain sensitive information from kernel stack memory by triggering failure of a get_user_ex call.(CVE-2016-9178i1/4%0\n\n - It was found that the x86 ISA (Instruction Set Architecture) is prone to a denial of service attack inside a virtualized environment in the form of an infinite loop in the microcode due to the way (sequential) delivering of benign exceptions such as #DB (debug exception) is handled. A privileged user inside a guest could use this flaw to create denial of service conditions on the host kernel.(CVE-2015-8104i1/4%0\n\n - The Direct Rendering Manager (DRM) subsystem in the Linux kernel through 4.x mishandles requests for Graphics Execution Manager (GEM) objects, which allows context-dependent attackers to cause a denial of service (memory consumption) via an application that processes graphics data, as demonstrated by JavaScript code that creates many CANVAS elements for rendering by Chrome or Firefox.(CVE-2013-7445i1/4%0\n\n - A flaw was found in the Linux kernel which does not initialize certain data structures used by DMA transfer on ARM64 based systems. This could allow local users to obtain sensitive information from kernel memory by triggering a dma_mmap call and reconstructing the data.(CVE-2015-8950i1/4%0\n\n - A race condition was found in the Linux kernel before version 4.11-rc1 in 'fs/timerfd.c' file which allows a local user to cause a kernel list corruption or use-after-free via simultaneous operations with a file descriptor which leverage improper 'might_cancel' queuing. An unprivileged local user could use this flaw to cause a denial of service of the system. Due to the nature of the flaw, privilege escalation cannot be fully ruled out, although we believe it is unlikely.(CVE-2017-10661i1/4%0\n\n - The sg_ioctl() function in 'drivers/scsi/sg.c' in the Linux kernel, from version 4.12-rc1 to 4.14-rc2, allows local users to obtain sensitive information from uninitialized kernel heap-memory locations via an SG_GET_REQUEST_TABLE ioctl call for '/dev/sg0'.(CVE-2017-14991i1/4%0\n\n - A race condition in the ip4_datagram_release_cb function in net/ipv4/datagram.c in the Linux kernel allows local users to gain privileges or cause a denial of service (use-after-free) by leveraging incorrect expectations about locking during multithreaded access to internal data structures for IPv4 UDP sockets.(CVE-2014-9914i1/4%0\n\nNote that Tenable Network Security has extracted the preceding description block directly from the EulerOS security advisory.

This could\n lead to bypassing the permissions on a Unix socket and\n packets being injected into the stream, and could also\n panic the machine (denial of service).(CVE-2013-7446i1/4%0\n\n - The do_check function in kernel/bpf/verifier.c in the\n Linux kernel before 4.11.1 does not make the\n allow_ptr_leaks value available for restricting the\n output of the print_bpf_insn function, which allows\n local users to obtain sensitive address information via\n crafted bpf system calls.(CVE-2017-9150i1/4%0\n\n - The WLAN (aka Wi-Fi) driver for the Linux kernel 3.x\n and 4.x, as used in Qualcomm Innovation Center (QuIC)\n Android contributions for MSM devices and other\n products, does not verify authorization for private SET\n IOCTL calls, which allows attackers to gain privileges\n via a crafted application, related to\n wlan_hdd_hostapd.c and\n wlan_hdd_wext.c.(CVE-2015-0571i1/4%0\n\n - arch/arm64/kvm/guest.c in KVM in the Linux kernel\n before 4.18.12 on the arm64 platform mishandles the\n KVM_SET_ON_REG ioctl. This is exploitable by attackers\n who can create virtual machines. An attacker can\n arbitrarily redirect the hypervisor flow of control\n (with full register control). An attacker can also\n cause a denial of service (hypervisor panic) via an\n illegal exception return. This occurs because of\n insufficient restrictions on userspace access to the\n core register file, and because PSTATE.M validation\n does not prevent unintended execution\n modes.(CVE-2018-18021i1/4%0\n\n - A resource-exhaustion vulnerability was found in the\n kernel, where an unprivileged process could allocate\n and accumulate far more file descriptors than the\n process' limit. A local, unauthenticated user could\n exploit this flaw by sending file descriptors over a\n Unix socket and then closing them to keep the process'\n fd count low, thereby creating kernel-memory or\n file-descriptors exhaustion (denial of\n service).(CVE-2016-2550i1/4%0\n\n - The Linux kernel before 3.12.4 updates certain length\n values before ensuring that associated data structures\n have been initialized, which allows local users to\n obtain sensitive information from kernel stack memory\n via a (1) recvfrom, (2) recvmmsg, or (3) recvmsg system\n call, related to net/ipv4/ping.c, net/ipv4/raw.c,\n net/ipv4/udp.c, net/ipv6/raw.c, and\n net/ipv6/udp.c.(CVE-2013-7263i1/4%0\n\n - It is possible for a single process to cause an OOM\n condition by filling large pipes with data that are\n never read. A typical process filling 4096 pipes with 1\n MB of data will use 4 GB of memory and there can be\n multiple such processes, up to a\n per-user-limit.(CVE-2016-2847i1/4%0\n\n - The __get_user_asm_ex macro in\n arch/x86/include/asm/uaccess.h in the Linux kernel\n before 4.7.5 does not initialize a certain integer\n variable, which allows local users to obtain sensitive\n information from kernel stack memory by triggering\n failure of a get_user_ex call.(CVE-2016-9178i1/4%0\n\n - It was found that the x86 ISA (Instruction Set\n Architecture) is prone to a denial of service attack\n inside a virtualized environment in the form of an\n infinite loop in the microcode due to the way\n (sequential) delivering of benign exceptions such as\n #DB (debug exception) is handled. A privileged user\n inside a guest could use this flaw to create denial of\n service conditions on the host kernel.(CVE-2015-8104i1/4%0\n\n - The Direct Rendering Manager (DRM) subsystem in the\n Linux kernel through 4.x mishandles requests for\n Graphics Execution Manager (GEM) objects, which allows\n context-dependent attackers to cause a denial of\n service (memory consumption) via an application that\n processes graphics data, as demonstrated by JavaScript\n code that creates many CANVAS elements for rendering by\n Chrome or Firefox.(CVE-2013-7445i1/4%0\n\n - A flaw was found in the Linux kernel which does not\n initialize certain data structures used by DMA transfer\n on ARM64 based systems. This could allow local users to\n obtain sensitive information from kernel memory by\n triggering a dma_mmap call and reconstructing the\n data.(CVE-2015-8950i1/4%0\n\n - A race condition was found in the Linux kernel before\n version 4.11-rc1 in 'fs/timerfd.c' file which allows a\n local user to cause a kernel list corruption or\n use-after-free via simultaneous operations with a file\n descriptor which leverage improper 'might_cancel'\n queuing. An unprivileged local user could use this flaw\n to cause a denial of service of the system. Due to the\n nature of the flaw, privilege escalation cannot be\n fully ruled out, although we believe it is\n unlikely.(CVE-2017-10661i1/4%0\n\n - The sg_ioctl() function in 'drivers/scsi/sg.c' in the\n Linux kernel, from version 4.12-rc1 to 4.14-rc2, allows\n local users to obtain sensitive information from\n uninitialized kernel heap-memory locations via an\n SG_GET_REQUEST_TABLE ioctl call for\n '/dev/sg0'.(CVE-2017-14991i1/4%0\n\n - A race condition in the ip4_datagram_release_cb\n function in net/ipv4/datagram.c in the Linux kernel\n allows local users to gain privileges or cause a denial\n of service (use-after-free) by leveraging incorrect\n expectations about locking during multithreaded access\n to internal data structures for IPv4 UDP\n sockets.(CVE-2014-9914i1/4%0\n\nNote that Tenable Network Security has extracted the preceding\ndescription block directly from the EulerOS security advisory.

This field is not bounds checked prior to writing to a counter value at the supplied offset.(CVE-2016-3134)\n\n - An integer overflow vulnerability was found in the Linux kernel in xt_alloc_table_info, which on 32-bit systems can lead to small structure allocation and a copy_from_user based heap corruption.(CVE-2016-3135)\n\n - The mct_u232_msr_to_state function in drivers/usb/serial/mct_u232.c in the Linux kernel before 4.5.1 allows physically proximate attackers to cause a denial of service (NULL pointer dereference and system crash) via a crafted USB device without two interrupt-in endpoint descriptors.(CVE-2016-3136)\n\n - drivers/usb/serial/cypress_m8.c in the Linux kernel before 4.5.1 allows physically proximate attackers to cause a denial of service (NULL pointer dereference and system crash) via a USB device without both an interrupt-in and an interrupt-out endpoint descriptor, related to the cypress_generic_port_probe and cypress_open functions.(CVE-2016-3137)\n\n - The acm_probe function in drivers/usb/class/cdc-acm.c in the Linux kernel before 4.5.1 allows physically proximate attackers to cause a denial of service (NULL pointer dereference and system crash) via a USB device without both a control and a data endpoint descriptor.(CVE-2016-3138)\n\n - The wacom_probe function in drivers/input/tablet/wacom_sys.c in the Linux kernel before 3.17 allows physically proximate attackers to cause a denial of service (NULL pointer dereference and system crash) via a crafted endpoints value in a USB device descriptor.(CVE-2016-3139)\n\n - The digi_port_init function in drivers/usb/serial/digi_acceleport.c in the Linux kernel before 4.5.1 allows physically proximate attackers to cause a denial of service (NULL pointer dereference and system crash) via a crafted endpoints value in a USB device descriptor.(CVE-2016-3140)\n\n - 'A security flaw was found in the Linux kernel's networking subsystem that destroying the network interface with huge number of ipv4 addresses assigned keeps ''rtnl_lock'' spinlock for a very long time (up to hour). This blocks many network-related operations, including creation of new incoming ssh connections.\n\n - The problem is especially important for containers, as the container owner has enough permissions to trigger this and block a network access on a whole host, outside the container.(CVE-2016-3156)'\n\n - A weakness was found in the Linux ASLR implementation.\n Any user able to running 32-bit applications in a x86 machine can disable ASLR by setting the RLIMIT_STACK resource to unlimited.(CVE-2016-3672)\n\n - The ims_pcu_parse_cdc_data function in drivers/input/misc/ims-pcu.c in the Linux kernel before 4.5.1 allows physically proximate attackers to cause a denial of service (system crash) via a USB device without both a master and a slave interface.(CVE-2016-3689)\n\n - It was found that the Linux kernel's IPv6 implementation mishandled socket options. A local attacker could abuse concurrent access to the socket options to escalate their privileges, or cause a denial of service (use-after-free and system crash) via a crafted sendmsg system call.(CVE-2016-3841)\n\n - The usbip_recv_xbuff function in drivers/usb/usbip/usbip_common.c in the Linux kernel before 4.5.3 allows remote attackers to cause a denial of service (out-of-bounds write) or possibly have unspecified other impact via a crafted length value in a USB/IP packet.(CVE-2016-3955)\n\n - A flaw was found in the Linux kernel's keyring handling code: the key_reject_and_link() function could be forced to free an arbitrary memory block. An attacker could use this flaw to trigger a use-after-free condition on the system, potentially allowing for privilege escalation.(CVE-2016-4470)\n\n - The proc_connectinfo() function in 'drivers/usb/core/devio.c' in the Linux kernel through 4.6 does not initialize a certain data structure, which allows local users to obtain sensitive information from kernel stack memory via a crafted USBDEVFS_CONNECTINFO ioctl call. The stack object 'ci' has a total size of 8 bytes. Its last 3 bytes are padding bytes which are not initialized and are leaked to userland.(CVE-2016-4482)\n\n - A flaw was found in the way certain interfaces of the Linux kernel's Infiniband subsystem used write() as bi-directional ioctl() replacement, which could lead to insufficient memory security checks when being invoked using the splice() system call. A local unprivileged user on a system with either Infiniband hardware present or RDMA Userspace Connection Manager Access module explicitly loaded, could use this flaw to escalate their privileges on the system.(CVE-2016-4565)\n\nNote that Tenable Network Security has extracted the preceding description block directly from the EulerOS security advisory.

A Common Vulnerability Scoring System (CVSS) base score, which gives a detailed severity rating, is available for each vulnerability from the CVE link(s) in the References section.\n\nThe kernel packages contain the Linux kernel, the core of any Linux operating system.\n\nSecurity Fix(es) :\n\n* It was found that reporting emulation failures to user space could lead to either a local (CVE-2014-7842) or a L2->L1 (CVE-2010-5313) denial of service. In the case of a local denial of service, an attacker must have access to the MMIO area or be able to access an I/O port. Please note that on certain systems, HPET is mapped to userspace as part of vdso (vvar) and thus an unprivileged user may generate MMIO transactions (and enter the emulator) this way. (CVE-2010-5313, CVE-2014-7842, Moderate)\n\n* It was found that the Linux kernel did not properly account file descriptors passed over the unix socket against the process limit. A local user could use this flaw to exhaust all available memory on the system. (CVE-2013-4312, Moderate)\n\n* A buffer overflow flaw was found in the way the Linux kernel's virtio-net subsystem handled certain fraglists when the GRO (Generic Receive Offload) functionality was enabled in a bridged network configuration. An attacker on the local network could potentially use this flaw to crash the system, or, although unlikely, elevate their privileges on the system. (CVE-2015-5156, Moderate)\n\n* It was found that the Linux kernel's IPv6 network stack did not properly validate the value of the MTU variable when it was set. A remote attacker could potentially use this flaw to disrupt a target system's networking (packet loss) by setting an invalid MTU value, for example, via a NetworkManager daemon that is processing router advertisement packets running on the target system. (CVE-2015-8215, Moderate)\n\n* A NULL pointer dereference flaw was found in the way the Linux kernel's network subsystem handled socket creation with an invalid protocol identifier. A local user could use this flaw to crash the system. (CVE-2015-8543, Moderate)\n\n* It was found that the espfix functionality does not work for 32-bit KVM paravirtualized guests. A local, unprivileged guest user could potentially use this flaw to leak kernel stack addresses.\n(CVE-2014-8134, Low)\n\n* A flaw was found in the way the Linux kernel's ext4 file system driver handled non-journal file systems with an orphan list. An attacker with physical access to the system could use this flaw to crash the system or, although unlikely, escalate their privileges on the system. (CVE-2015-7509, Low)\n\n* A NULL pointer dereference flaw was found in the way the Linux kernel's ext4 file system driver handled certain corrupted file system images.

(CVE-2014-8134)\n\n - The virtnet_probe function in drivers/net/virtio_net.c in the Linux kernel before 4.2 attempts to support a FRAGLIST feature without proper memory allocation, which allows guest OS users to cause a denial of service (buffer overflow and memory corruption) via a crafted sequence of fragmented packets.\n (CVE-2015-5156)\n\n - Race condition in arch/x86/kvm/x86.c in the Linux kernel before 2.6.38 allows L2 guest OS users to cause a denial of service (L1 guest OS crash) via a crafted instruction that triggers an L2 emulation failure report, a similar issue to CVE-2014-7842. (CVE-2010-5313)\n\n - Race condition in arch/x86/kvm/x86.c in the Linux kernel before 3.17.4 allows guest OS users to cause a denial of service (guest OS crash) via a crafted application that performs an MMIO transaction or a PIO transaction to trigger a guest userspace emulation error report, a similar issue to CVE-2010-5313.\n (CVE-2014-7842)\n\n - The Linux kernel before 4.4.1 allows local users to bypass file-descriptor limits and cause a denial of service (memory consumption) by sending each descriptor over a UNIX socket before closing it, related to net/unix/af_unix.c and net/unix/garbage.c.

various security and bugfixes. For the PowerPC64 a new 'bigmem' flavor has been added to support big Power machines. (FATE#319026) The following security bugs were fixed :\n\n - CVE-2016-7042: The proc_keys_show function in security/keys/proc.c in the Linux kernel, when the GNU Compiler Collection (gcc) stack protector is enabled, uses an incorrect buffer size for certain timeout data, which allowed local users to cause a denial of service (stack memory corruption and panic) by reading the /proc/keys file (bnc#1004517).\n\n - CVE-2016-7097: The filesystem implementation in the Linux kernel preserves the setgid bit during a setxattr call, which allowed local users to gain group privileges by leveraging the existence of a setgid program with restrictions on execute permissions (bnc#995968).\n\n - CVE-2015-8956: The rfcomm_sock_bind function in net/bluetooth/rfcomm/sock.c in the Linux kernel allowed local users to obtain sensitive information or cause a denial of service (NULL pointer dereference) via vectors involving a bind system call on a Bluetooth RFCOMM socket (bnc#1003925).\n\n - CVE-2016-7117: Use-after-free vulnerability in the\n __sys_recvmmsg function in net/socket.c in the Linux kernel allowed remote attackers to execute arbitrary code via vectors involving a recvmmsg system call that is mishandled during error processing (bnc#1003077).\n\n - CVE-2016-0823: The pagemap_open function in fs/proc/task_mmu.c in the Linux kernel allowed local users to obtain sensitive physical-address information by reading a pagemap file, aka Android internal bug 25739721 (bnc#994759).\n\n - CVE-2016-7425: The arcmsr_iop_message_xfer function in drivers/scsi/arcmsr/arcmsr_hba.c in the Linux kernel did not restrict a certain length field, which allowed local users to gain privileges or cause a denial of service (heap-based buffer overflow) via an ARCMSR_MESSAGE_WRITE_WQBUFFER control code (bnc#999932).\n\n - CVE-2016-3841: The IPv6 stack in the Linux kernel mishandled options data, which allowed local users to gain privileges or cause a denial of service (use-after-free and system crash) via a crafted sendmsg system call (bnc#992566).\n\n - CVE-2016-6828: The tcp_check_send_head function in include/net/tcp.h in the Linux kernel did not properly maintain certain SACK state after a failed data copy, which allowed local users to cause a denial of service (tcp_xmit_retransmit_queue use-after-free and system crash) via a crafted SACK option (bnc#994296).\n\n - CVE-2016-5696: net/ipv4/tcp_input.c in the Linux kernel did not properly determine the rate of challenge ACK segments, which made it easier for remote attackers to hijack TCP sessions via a blind in-window attack (bnc#989152).\n\n - CVE-2016-6480: Race condition in the ioctl_send_fib function in drivers/scsi/aacraid/commctrl.c in the Linux kernel allowed local users to cause a denial of service (out-of-bounds access or system crash) by changing a certain size value, aka a 'double fetch' vulnerability (bnc#991608).\n\n - CVE-2016-4998: The IPT_SO_SET_REPLACE setsockopt implementation in the netfilter subsystem in the Linux kernel allowed local users to cause a denial of service (out-of-bounds read) or possibly obtain sensitive information from kernel heap memory by leveraging in-container root access to provide a crafted offset value that leads to crossing a ruleset blob boundary (bnc#986365).\n\n - CVE-2015-7513: arch/x86/kvm/x86.c in the Linux kernel did not reset the PIT counter values during state restoration, which allowed guest OS users to cause a denial of service (divide-by-zero error and host OS crash) via a zero value, related to the kvm_vm_ioctl_set_pit and kvm_vm_ioctl_set_pit2 functions (bnc#960689).\n\n - CVE-2013-4312: The Linux kernel allowed local users to bypass file-descriptor limits and cause a denial of service (memory consumption) by sending each descriptor over a UNIX socket before closing it, related to net/unix/af_unix.c and net/unix/garbage.c (bnc#839104 bsc#922947 bsc#968014).\n\nThe update package also includes non-security fixes.

A local, unprivileged\n user on a PowerPC system that supports transactional\n memory could use this flaw to crash the\n system.(CVE-2014-2673i1/4%0\n\n - The hashbin_delete function in net/irda/irqueue.c in\n the Linux kernel improperly manages lock dropping,\n which allows local users to cause a denial of service\n (deadlock) via crafted operations on IrDA\n devices.(CVE-2017-6348i1/4%0\n\n - An out-of-bounds flaw was found in the kernel, where\n the length of the sockaddr parameter was not checked in\n the pptp_bind() and pptp_connect() functions. As a\n result, more kernel memory was copied out than\n required, leaking information from the kernel stack\n (including kernel addresses). A local system user could\n exploit this flaw to bypass kernel ASLR or leak other\n information.(CVE-2015-8569i1/4%0\n\nNote that Tenable Network Security has extracted the preceding\ndescription block directly from the EulerOS security advisory.

Linux kernel before 4.4 allows local users to cause a denial of service (infinite loop) via a writev system call that triggers a zero length for the first segment of an iov. (CVE-2015-8785)\n\n - The hub_activate function in drivers/usb/core/hub.c in the Linux kernel before 4.3.5 does not properly maintain a hub-interface data structure, which allows physically proximate attackers to cause a denial of service (invalid memory access and system crash) or possibly have unspecified other impact by unplugging a USB hub device. (CVE-2015-8816)\n\n - Race condition in arch/x86/mm/tlb.c in the Linux kernel before 4.4.1 allows local users to gain privileges by triggering access to a paging structure by a different CPU. (CVE-2016-2069)\n\n - The IPv4 implementation in the Linux kernel before 4.5.2 mishandles destruction of device objects, which allows guest OS users to cause a denial of service (host OS networking outage) by arranging for a large number of IP addresses. (CVE-2016-3156)\n\n - fs/pnode.c in the Linux kernel before 4.5.4 does not properly traverse a mount propagation tree in a certain case involving a slave mount, which allows local users to cause a denial of service (NULL pointer dereference and OOPS) via a crafted series of mount system calls. (CVE-2016-4581)\n\n - Use-after-free vulnerability in drivers/net/ppp/ppp_generic.c in the Linux kernel before 4.5.2 allows local users to cause a denial of service (memory corruption and system crash, or spinlock) or possibly have unspecified other impact by removing a network namespace, related to the ppp_register_net_channel and ppp_unregister_channel functions. (CVE-2016-4805)\n\n - The get_rock_ridge_filename function in fs/isofs/rock.c in the Linux kernel before 4.5.5 mishandles NM (aka alternate name) entries containing \\0 characters, which allows local users to obtain sensitive information from kernel memory or possibly have unspecified other impact via a crafted isofs filesystem.\n (CVE-2016-4913)\n\n - The tipc_nl_publ_dump function in net/tipc/socket.c in the Linux kernel through 4.6 does not verify socket existence, which allows local users to cause a denial of service (NULL pointer dereference and system crash) or possibly have unspecified other impact via a dumpit operation. (CVE-2016-4951)\n\n - The nf_nat_redirect_ipv4 function in net/netfilter/nf_nat_redirect.c in the Linux kernel before 4.4 allows remote attackers to cause a denial of service (NULL pointer dereference and system crash) or possibly have unspecified other impact by sending certain IPv4 packets to an incompletely configured interface, a related issue to CVE-2003-1604. (CVE-2015-8787)\n\n - Race condition in the tty_ioctl function in drivers/tty/tty_io.c in the Linux kernel through 4.4.1 allows local users to obtain sensitive information from kernel memory or cause a denial of service (use-after- free and system crash) by making a TIOCGETD ioctl call during processing of a TIOCSETD ioctl call.\n (CVE-2016-0723)\n\n - fs/pipe.c in the Linux kernel before 4.5 does not limit the amount of unread data in pipes, which allows local users to cause a denial of service (memory consumption) by creating many pipes with non-default sizes.

(CVE-2016-4581)\n\n - fs/pipe.c in the Linux kernel before 4.5 does not limit the amount of unread data in pipes, which allows local users to cause a denial of service (memory consumption) by creating many pipes with non-default sizes. (CVE-2016-2847)\n\n - fs/btrfs/inode.c in the Linux kernel before 4.3.3 mishandles compressed inline extents, which allows local users to obtain sensitive pre-truncation information from a file via a clone action. (CVE-2015-8374)\n\n - Multiple heap-based buffer overflows in the hiddev_ioctl_usage function in drivers/hid/usbhid/hiddev.c in the Linux kernel through 4.6.3 allow local users to cause a denial of service or possibly have unspecified other impact via a crafted (1) HIDIOCGUSAGES or (2) HIDIOCSUSAGES ioctl call. (CVE-2016-5829)\n\n - The signal implementation in the Linux kernel before 4.3.5 on powerpc platforms does not check for an MSR with both the S and T bits set, which allows local users to cause a denial of service (TM Bad Thing exception and panic) via a crafted application. (CVE-2015-8844)\n\n - The tm_reclaim_thread function in arch/powerpc/kernel/process.c in the Linux kernel before 4.4.1 on powerpc platforms does not ensure that TM suspend mode exists before proceeding with a tm_reclaim call, which allows local users to cause a denial of service (TM Bad Thing exception and panic) via a crafted application. (CVE-2015-8845)\n\n - The rfcomm_sock_bind function in net/bluetooth/rfcomm/sock.c in the Linux kernel before 4.2 allows local users to obtain sensitive information or cause a denial of service (NULL pointer dereference) via vectors involving a bind system call on a Bluetooth RFCOMM socket. (CVE-2015-8956)\n\n - The asn1_ber_decoder function in lib/asn1_decoder.c in the Linux kernel before 4.3 allows attackers to cause a denial of service (panic) via an ASN.1 BER file that lacks a public key, leading to mishandling by the public_key_verify_signature function in crypto/asymmetric_keys/public_key.c. (CVE-2016-2053)\n\n - Double free vulnerability in the snd_usbmidi_create function in sound/usb/midi.c in the Linux kernel before 4.5 allows physically proximate attackers to cause a denial of service (panic) or possibly have unspecified other impact via vectors involving an invalid USB descriptor. (CVE-2016-2384)\n\n - The snd_timer_user_params function in sound/core/timer.c in the Linux kernel through 4.6 does not initialize a certain data structure, which allows local users to obtain sensitive information from kernel stack memory via crafted use of the ALSA timer interface. (CVE-2016-4569)\n\n - sound/core/timer.c in the Linux kernel through 4.6 does not initialize certain r1 data structures, which allows local users to obtain sensitive information from kernel stack memory via crafted use of the ALSA timer interface, related to the (1) snd_timer_user_ccallback and (2) snd_timer_user_tinterrupt functions.\n (CVE-2016-4578)\n\n - arch/powerpc/kvm/book3s_hv_rmhandlers.S in the Linux kernel through 4.7 on PowerPC platforms, when CONFIG_KVM_BOOK3S_64_HV is enabled, allows guest OS users to cause a denial of service (host OS infinite loop) by making a H_CEDE hypercall during the existence of a suspended transaction. (CVE-2016-5412)\n\n - drivers/infiniband/ulp/srpt/ib_srpt.c in the Linux kernel before 4.5.1 allows local users to cause a denial of service (NULL pointer dereference and system crash) by using an ABORT_TASK command to abort a device write operation. (CVE-2016-6327)\n\n - Race condition in the ioctl_send_fib function in drivers/scsi/aacraid/commctrl.c in the Linux kernel through 4.7 allows local users to cause a denial of service (out-of-bounds access or system crash) by changing a certain size value, aka a double fetch vulnerability. (CVE-2016-6480)\n\n - fs/nfs/nfs4proc.c in the NFS client in the Linux kernel before 4.2.2 does not properly initialize memory for migration recovery operations, which allows remote NFS servers to cause a denial of service (NULL pointer dereference and panic) via crafted network traffic. (CVE-2015-8746)\n\n - drivers/infiniband/hw/cxgb3/iwch_cm.c in the Linux kernel before 4.5 does not properly identify error conditions, which allows remote attackers to execute arbitrary code or cause a denial of service (use- after-free) via crafted packets. (CVE-2015-8812)\n\n - The trace_writeback_dirty_page implementation in include/trace/events/writeback.h in the Linux kernel before 4.4 improperly interacts with mm/migrate.c, which allows local users to cause a denial of service (NULL pointer dereference and system crash) or possibly have unspecified other impact by triggering a certain page move. (CVE-2016-3070)\n\n - The Linux kernel, as used in Red Hat Enterprise Linux 7.2 and Red Hat Enterprise MRG 2 and when booted with UEFI Secure Boot enabled, allows local users to bypass intended Secure Boot restrictions and execute untrusted code by appending ACPI tables to the initrd. (CVE-2016-3699)\n\n - The IPv6 stack in the Linux kernel before 4.3.3 mishandles options data, which allows local users to gain privileges or cause a denial of service (use-after-free and system crash) via a crafted sendmsg system call. (CVE-2016-3841)\n\n - Use-after-free vulnerability in mm/percpu.c in the Linux kernel through 4.6 allows local users to cause a denial of service (BUG) or possibly have unspecified other impact via crafted use of the mmap and bpf system calls.

CVE-2015-1350: The VFS subsystem in the Linux kernel 3.x provides an incomplete set of requirements for setattr operations that underspecified removing extended privilege attributes, which allowed local users to cause a denial of service (capability stripping) via a failed invocation of a system call, as demonstrated by using chown to remove a capability from the ping or Wireshark dumpcap program (bnc#914939).\n\n - CVE-2015-8962: Double free vulnerability in the sg_common_write function in drivers/scsi/sg.c in the Linux kernel allowed local users to gain privileges or cause a denial of service (memory corruption and system crash) by detaching a device during an SG_IO ioctl call (bnc#1010501).\n\n - CVE-2016-9555: The sctp_sf_ootb function in net/sctp/sm_statefuns.c in the Linux kernel lacked chunk-length checking for the first chunk, which allowed remote attackers to cause a denial of service (out-of-bounds slab access) or possibly have unspecified other impact via crafted SCTP data (bnc#1011685).\n\n - CVE-2016-7910: Use-after-free vulnerability in the disk_seqf_stop function in block/genhd.c in the Linux kernel allowed local users to gain privileges by leveraging the execution of a certain stop operation even if the corresponding start operation had failed (bnc#1010716).\n\n - CVE-2016-7911: Race condition in the get_task_ioprio function in block/ioprio.c in the Linux kernel allowed local users to gain privileges or cause a denial of service (use-after-free) via a crafted ioprio_get system call (bnc#1010711).\n\n - CVE-2015-8964: The tty_set_termios_ldisc function in drivers/tty/tty_ldisc.c in the Linux kernel allowed local users to obtain sensitive information from kernel memory by reading a tty data structure (bnc#1010507).\n\n - CVE-2016-7916: Race condition in the environ_read function in fs/proc/base.c in the Linux kernel allowed local users to obtain sensitive information from kernel memory by reading a /proc/*/environ file during a process-setup time interval in which environment-variable copying is incomplete (bnc#1010467).\n\n - CVE-2016-8646: The hash_accept function in crypto/algif_hash.c in the Linux kernel allowed local users to cause a denial of service (OOPS) by attempting to trigger use of in-kernel hash algorithms for a socket that has received zero bytes of data (bnc#1010150).\n\n - CVE-2016-8633: drivers/firewire/net.c in the Linux kernel before 4.8.7, in certain unusual hardware configurations, allowed remote attackers to execute arbitrary code via crafted fragmented packets (bnc#1008833).\n\n - CVE-2016-7042: The proc_keys_show function in security/keys/proc.c in the Linux kernel used an incorrect buffer size for certain timeout data, which allowed local users to cause a denial of service (stack memory corruption and panic) by reading the /proc/keys file (bnc#1004517).\n\n - CVE-2016-7097: The filesystem implementation in the Linux kernel preserves the setgid bit during a setxattr call, which allowed local users to gain group privileges by leveraging the existence of a setgid program with restrictions on execute permissions (bnc#995968).\n\n - CVE-2017-5551: The filesystem implementation in the Linux kernel preserves the setgid bit during a setxattr call, which allowed local users to gain group privileges by leveraging the existence of a setgid program with restrictions on execute permissions. This CVE tracks the fix for the tmpfs filesystem. (bsc#1021258).\n\n - CVE-2015-8956: The rfcomm_sock_bind function in net/bluetooth/rfcomm/sock.c in the Linux kernel allowed local users to obtain sensitive information or cause a denial of service (NULL pointer dereference) via vectors involving a bind system call on a Bluetooth RFCOMM socket (bnc#1003925).\n\n - CVE-2016-7117: Use-after-free vulnerability in the\n __sys_recvmmsg function in net/socket.c in the Linux kernel allowed remote attackers to execute arbitrary code via vectors involving a recvmmsg system call that is mishandled during error processing (bnc#1003077).\n\n - CVE-2016-0823: The pagemap_open function in fs/proc/task_mmu.c in the Linux kernel allowed local users to obtain sensitive physical-address information by reading a pagemap file, aka Android internal bug 25739721 (bnc#994759).\n\n - CVE-2016-7425: The arcmsr_iop_message_xfer function in drivers/scsi/arcmsr/arcmsr_hba.c in the Linux kernel did not restrict a certain length field, which allowed local users to gain privileges or cause a denial of service (heap-based buffer overflow) via an ARCMSR_MESSAGE_WRITE_WQBUFFER control code (bnc#999932).\n\n - CVE-2016-6828: The tcp_check_send_head function in include/net/tcp.h in the Linux kernel did not properly maintain certain SACK state after a failed data copy, which allowed local users to cause a denial of service (tcp_xmit_retransmit_queue use-after-free and system crash) via a crafted SACK option (bnc#994296).\n\n - CVE-2016-6480: Race condition in the ioctl_send_fib function in drivers/scsi/aacraid/commctrl.c in the Linux kernel allowed local users to cause a denial of service (out-of-bounds access or system crash) by changing a certain size value, aka a 'double fetch' vulnerability (bnc#991608).\n\n -

CVE-2016-4485: The llc_cmsg_rcv function in\n net/llc/af_llc.c in the Linux kernel did not initialize\n a certain data structure, which allowed attackers to\n obtain sensitive information from kernel stack memory by\n reading a message (bnc#978821).\n\n - CVE-2016-4578: sound/core/timer.c in the Linux kernel\n did not initialize certain r1 data structures, which\n allowed local users to obtain sensitive information from\n kernel stack memory via crafted use of the ALSA timer\n interface, related to the (1) snd_timer_user_ccallback\n and (2) snd_timer_user_tinterrupt functions\n (bnc#979879).\n\n - CVE-2016-4569: The snd_timer_user_params function in\n sound/core/timer.c in the Linux kernel did not\n initialize a certain data structure, which allowed local\n users to obtain sensitive information from kernel stack\n memory via crafted use of the ALSA timer interface\n (bnc#979213).\n\nThe update package also includes non-security fixes. See advisory for\ndetails.\n\nNote that Tenable Network Security has extracted the preceding\ndescription block directly from the SUSE security advisory. Tenable\nhas attempted to automatically clean and format it as much as possible\nwithout introducing additional issues.\"\n );\n script_set_attribute(\n attribute:\"see_also\",\n value:\"https://bugzilla.suse.com/show_bug.cgi?id=1003077\"\n );\n script_set_attribute(\n attribute:\"see_also\",\n value:\"https://bugzilla.suse.com/show_bug.cgi?id=1003925\"\n );\n script_set_attribute(\n attribute:\"see_also\",\n value:\"https://bugzilla.suse.com/show_bug.cgi?id=1004517\"\n );\n script_set_attribute(\n attribute:\"see_also\",\n value:\"https://bugzilla.suse.com/show_bug.cgi?id=1007944\"\n );\n script_set_attribute(\n attribute:\"see_also\",\n value:\"https://bugzilla.suse.com/show_bug.cgi?id=1008645\"\n );\n script_set_attribute(\n attribute:\"see_also\",\n value:\"https://bugzilla.suse.com/show_bug.cgi?id=1008831\"\n );\n script_set_attribute(\n attribute:\"see_also\",\n value:\"https://bugzilla.suse.com/show_bug.cgi?id=1008833\"\n );\n script_set_attribute(\n attribute:\"see_also\",\n value:\"https://bugzilla.suse.com/show_bug.cgi?id=1009443\"\n );\n script_set_attribute(\n attribute:\"see_also\",\n value:\"https://bugzilla.suse.com/show_bug.cgi?id=1010150\"\n );\n script_set_attribute(\n attribute:\"see_also\",\n value:\"https://bugzilla.suse.com/show_bug.cgi?id=1010467\"\n );\n script_set_attribute(\n attribute:\"see_also\",\n value:\"https://bugzilla.suse.com/show_bug.cgi?id=1010501\"\n );\n script_set_attribute(\n attribute:\"see_also\",\n value:\"https://bugzilla.suse.com/show_bug.cgi?id=1010507\"\n );\n script_set_attribute(\n attribute:\"see_also\",\n
