A use-after-free is possible in try_merge_free_space() when mounting a crafted btrfs image due to a lack of chunk type flag checks in btrfs_check_chunk_valid() in the fs/btrfs/volumes.c function. This could lead to a denial of service or other unspecified impact.(CVE-2018-14611)\n\nA flaw was found in the way the Linux kernel visor driver handles certain invalid USB device descriptors. The driver assumes that the device always has at least one bulk OUT endpoint. By using a specially crafted USB device (without a bulk OUT endpoint), an unprivileged user with physical access could trigger a kernel NULL-pointer dereference and cause a system panic (denial of service).(CVE-2015-7566)\n\nIt was found that the RFC 5961 challenge ACK rate limiting as implemented in the Linux kernel's networking subsystem allowed an off-path attacker to leak certain information about a given connection by creating congestion on the global challenge ACK rate limit counter and then measuring the changes by probing packets. An off-path attacker could use this flaw to either terminate TCP connection and/or inject payload into non-secured TCP connection between two endpoints on the network.(CVE-2016-5696)\n\nIt was found that the Bluebooth Network Encapsulation Protocol (BNEP) implementation did not validate the type of second socket passed to the BNEPCONNADD ioctl(), which could lead to memory corruption. A local user with the CAP_NET_ADMIN capability can use this for denial of service (crash or data corruption) or possibly for privilege escalation. Due to the nature of the flaw, privilege escalation cannot be fully ruled out, although we feel it is unlikely.(CVE-2017-15868)\n\nA vulnerability was found in the key management subsystem of the Linux kernel. An update on an uninstantiated key could cause a kernel panic, leading to denial of service (DoS).(CVE-2017-15299)\n\nThe 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\narch/mips/include/asm/thread_info.h in the Linux kernel before 3.14.8 on the MIPS platform does not configure _TIF_SECCOMP checks on the fast system-call path, which allows loca ...\n\n Description truncated.

A local users could obtain sensitive information from kernel memory and bypass the KASLR protection mechanism (in the kernel through 4.9) via a crafted ACPI table.(CVE-2017-11472)\n\nRace condition in net/packet/af_packet.c in the Linux kernel allows local users to cause a denial of service (use-after-free) or possibly have unspecified other impact via a multithreaded application that makes PACKET_FANOUT setsockopt system calls.(CVE-2017-6346)\n\nMultiple race conditions in ipc/shm.c in the Linux kernel before 3.12.2 allow local users to cause a denial of service (use-after-free and system crash) or possibly have unspecified other impact via a crafted application that uses shmctl IPC_RMID operations in conjunction with other shm system calls.(CVE-2013-7026)\n\nAn issue was discovered in the Linux kernel. A NULL pointer dereference and panic in hfsplus_lookup() in the fs/hfsplus/dir.c function can occur when opening a file (that is purportedly a hard link) in an hfs+ filesystem that has malformed catalog data, and is mounted read-only without a metadata directory.(CVE-2018-14617)\n\nThe treo_attach function in drivers/usb/serial/visor.c in the Linux kernel before 4.5 allows physically proximate attackers to cause a denial of service (NULL pointer dereference and system crash) or possibly have unspecified other impact by inserting a USB device that lacks a (1) bulk-in or (2) interrupt-in endpoint.(CVE-2016-2782)\n\nAn information-exposure flaw was found in the Linux kernel where the pcpu_embed_first_chunk() function in mm/percpu.c allows local users to obtain kernel-object address information by reading the kernel log (dmesg). However, this address is not static and cannot be used to commit a further attack.(CVE-2018-5995)\n\nBuffer overflow in net/ceph/auth_x.c in Ceph, as used in the Linux kernel before 3.16.3, allows remote attackers to cause a denial of service (memory corruption a ...\n\n Description truncated.

This may allow remote attackers to corrupt memory and may allow execution of arbitrary code. This corruption takes place during the error handling routines within __sys_recvmmsg() function.(CVE-2016-7117)\n\nA heap-buffer overflow vulnerability was found in the arcmsr_iop_message_xfer() function in 'drivers/scsi/arcmsr/arcmsr_hba.c' file in the Linux kernel through 4.8.2. The function does not restrict a certain length field, which allows local users to gain privileges or cause a denial of service via an ARCMSR_MESSAGE_WRITE_WQBUFFER control code. This can potentially cause kernel heap corruption and arbitrary kernel code execution.(CVE-2016-7425)\n\nA flaw was found in the Linux kernel's implementation of seq_file where a local attacker could manipulate memory in the put() function pointer. This could lead to memory corruption and possible privileged escalation.(CVE-2016-7910)\n\nA use-after-free vulnerability in sys_ioprio_get() was found due to get_task_ioprio() accessing the task-io_context without holding the task lock and could potentially race with exit_io_context(), leading to a use-after-free.(CVE-2016-7911)\n\nThe xc2028_set_config function in drivers/media/tuners/tuner-xc2028.c in the Linux kernel before 4.6 allows local users to gain privileges or cause a denial of service (use-after-free) via vectors involving omission of the firmware name from a certain data structure. Due to the nature of the flaw, privilege escalation cannot be fully ruled out, although we believe it is unlikely.(CVE-2016-7913)\n\nThe assoc_array_insert_into_terminal_node() function in 'lib/assoc_array.c' in the Linux kernel before 4.5.3 does not check whether a slot is a leaf, which allows local users to obtain sensitive information from kernel memory or cause a denial of service (invalid pointer dereference and out-of-bounds read) via an application that uses associative-array data structures.(CVE-2016-7914)\n\nThe hid_input_field() function in 'drivers/hid/hid-core.c' in the Linux kernel before 4.6 allows physically proximate attackers to obtain sensitive information from kernel memory or cause a denial of service (out-of-bounds read) by connecting a device.(CVE-2016-7915)\n\nRace condition in the environ_read() function in 'fs/proc/base.c' in the Linux kernel before 4.5.4 allows 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.(CVE-2016-7916)\n\nA flaw was found in the Linux networking ...\n\n Description truncated.

NOTE: this is disputed because the code path is unreachable.(CVE-2014-3180)\n\nIn 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\nThere 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\nThere 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\ndrivers/gpu/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)\n\nThere 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\nA flaw was discovered in the way that the KVM hypervisor handled instruction emulation for an L2 guest when nested virtualisation is enabled.

The sg implementation in the Linux kernel through 4.9 does not properly restrict write operations in situations where the KERNEL_DS option is set, which allows local users to read or write to arbitrary kernel memory locations or cause a denial of service (use-after-free) by leveraging access to a /dev/sg device, related to block/bsg.c and drivers/scsi/sg.c. NOTE: this vulnerability exists because of an incomplete fix for CVE-2016-9576. (CVE-2016-10088)\n\n - The filesystem implementation in the Linux kernel through 4.8.2 preserves the setgid bit during a setxattr call, which allows local users to gain group privileges by leveraging the existence of a setgid program with restrictions on execute permissions. (CVE-2016-7097)\n\n - An elevation of privilege vulnerability in the kernel networking subsystem could enable a local malicious application to execute arbitrary code within the context of the kernel. This issue is rated as Moderate because it first requires compromising a privileged process and current compiler optimizations restrict access to the vulnerable code. Product: Android. Versions: Kernel-3.10, Kernel-3.18. Android ID:\n A-31349935. (CVE-2016-8399)\n\n - The sg_ioctl function in drivers/scsi/sg.c in the Linux kernel through 4.10.4 allows local users to cause a denial of service (stack-based buffer overflow) or possibly have unspecified other impact via a large command size in an SG_NEXT_CMD_LEN ioctl call, leading to out-of-bounds write access in the sg_write function. (CVE-2017-7187)\n\n - Race condition in drivers/tty/n_hdlc.c in the Linux kernel through 4.10.1 allows local users to gain privileges or cause a denial of service (double free) by setting the HDLC line discipline. (CVE-2017-2636)\n\n - crypto/mcryptd.c in the Linux kernel before 4.8.15 allows local users to cause a denial of service (NULL pointer dereference and system crash) by using an AF_ALG socket with an incompatible algorithm, as demonstrated by mcryptd(md5). (CVE-2016-10147)\n\n - arch/x86/kvm/vmx.c in the Linux kernel through 4.9 mismanages the #BP and #OF exceptions, which allows guest OS users to cause a denial of service (guest OS crash) by declining to handle an exception thrown by an L2 guest. (CVE-2016-9588)\n\n - The arcmsr_iop_message_xfer function in drivers/scsi/arcmsr/arcmsr_hba.c in the Linux kernel through 4.8.2 does not restrict a certain length field, which allows local users to gain privileges or cause a denial of service (heap-based buffer overflow) via an ARCMSR_MESSAGE_WRITE_WQBUFFER control code. (CVE-2016-7425)\n\n - drivers/firewire/net.c in the Linux kernel before 4.8.7, in certain unusual hardware configurations, allows remote attackers to execute arbitrary code via crafted fragmented packets. (CVE-2016-8633)\n\n - 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)\n\n - The arch_pick_mmap_layout function in arch/x86/mm/mmap.c in the Linux kernel through 4.5.2 does not properly randomize the legacy base address, which makes it easier for local users to defeat the intended restrictions on the ADDR_NO_RANDOMIZE flag, and bypass the ASLR protection mechanism for a setuid or setgid program, by disabling stack-consumption resource limits. (CVE-2016-3672)\n\n - The nested_vmx_check_vmptr function in arch/x86/kvm/vmx.c in the Linux kernel through 4.9.8 improperly emulates the VMXON instruction, which allows KVM L1 guest OS users to cause a denial of service (host OS memory consumption) by leveraging the mishandling of page references. (CVE-2017-2596)\n\n - 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)\n\n - The TCP stack in the Linux kernel before 4.8.10 mishandles skb truncation, which allows local users to cause a denial of service (system crash) via a crafted application that makes sendto system calls, related to net/ipv4/tcp_ipv4.c and net/ipv6/tcp_ipv6.c. (CVE-2016-8645)\n\n - The tipc_msg_build function in net/tipc/msg.c in the Linux kernel through 4.8.11 does not validate the relationship between the minimum fragment length and the maximum packet size, which allows local users to gain privileges or cause a denial of service (heap-based buffer overflow) by leveraging the CAP_NET_ADMIN capability. (CVE-2016-8632)\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-2016-9178)\n\n - The mbcache feature in the ext2 and ext4 filesystem implementations in the Linux kernel before 4.6 mishandles xattr block caching, which allows local users to cause a denial of service (soft lockup) via filesystem operations in environments that use many attributes, as demonstrated by Ceph and Samba.\n (CVE-2015-8952)\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 - The LLC subsystem in the Linux kernel before 4.9.13 does not ensure that a certain destructor exists in required circumstances, which allows local users to cause a denial of service (BUG_ON) or possibly have unspecified other impact via crafted system calls. (CVE-2017-6345)\n\n - The ipv4_pktinfo_prepare function in net/ipv4/ip_sockglue.c in the Linux kernel through 4.9.9 allows attackers to cause a denial of service (system crash) via (1) an application that makes crafted system calls or possibly (2) IPv4 traffic with invalid IP options. (CVE-2017-5970)\n\n - Race condition in kernel/events/core.c in the Linux kernel before 4.9.7 allows local users to gain privileges via a crafted application that makes concurrent perf_event_open system calls for moving a software group into a hardware context.

(CVE-2016-7097)\n\n - An elevation of privilege vulnerability in the kernel networking subsystem could enable a local malicious\n application to execute arbitrary code within the context of the kernel. This issue is rated as Moderate\n because it first requires compromising a privileged process and current compiler optimizations restrict\n access to the vulnerable code. Product: Android. Versions: Kernel-3.10, Kernel-3.18. Android ID:\n A-31349935. (CVE-2016-8399)\n\n - The sg_ioctl function in drivers/scsi/sg.c in the Linux kernel through 4.10.4 allows local users to cause\n a denial of service (stack-based buffer overflow) or possibly have unspecified other impact via a large\n command size in an SG_NEXT_CMD_LEN ioctl call, leading to out-of-bounds write access in the sg_write\n function.

"According to the versions of the kernel packages installed, the EulerOS Virtualization for ARM 64 installation on the remote host is affected by the following vulnerabilities :\n\n - The acpi_smbus_hc_add function in drivers/acpi/sbshc.c in the Linux kernel through 4.14.15 allows local users to obtain sensitive address information by reading dmesg data from an SBS HC printk call.(CVE-2018-5750i1/4%0\n\n - An issue was discovered in the btrfs filesystem code in the Linux kernel. A use-after-free is possible in try_merge_free_space() when mounting a crafted btrfs image due to a lack of chunk type flag checks in btrfs_check_chunk_valid() in the fs/btrfs/volumes.c function. This could lead to a denial of service or other unspecified impact.(CVE-2018-14611i1/4%0\n\n - A flaw was found in the way the Linux kernel visor driver handles certain invalid USB device descriptors.\n The driver assumes that the device always has at least one bulk OUT endpoint. By using a specially crafted USB device (without a bulk OUT endpoint), an unprivileged user with physical access could trigger a kernel NULL-pointer dereference and cause a system panic (denial of service).(CVE-2015-7566i1/4%0\n\n - It was found that the RFC 5961 challenge ACK rate limiting as implemented in the Linux kernel's networking subsystem allowed an off-path attacker to leak certain information about a given connection by creating congestion on the global challenge ACK rate limit counter and then measuring the changes by probing packets. An off-path attacker could use this flaw to either terminate TCP connection and/or inject payload into non-secured TCP connection between two endpoints on the network.(CVE-2016-5696i1/4%0\n\n - It was found that the Bluebooth Network Encapsulation Protocol (BNEP) implementation did not validate the type of second socket passed to the BNEPCONNADD ioctl(), which could lead to memory corruption. A local user with the CAP_NET_ADMIN capability can use this for denial of service (crash or data corruption) or possibly for privilege escalation. Due to the nature of the flaw, privilege escalation cannot be fully ruled out, although we feel it is unlikely.(CVE-2017-15868i1/4%0\n\n - A vulnerability was found in the key management subsystem of the Linux kernel.

Additionally, in kernel versions\nprior to 3.5, any user could do this if sysctl net.core.rmem_max was\nchanged to a very large value.\n\nCVE-2015-1350 / #770492\n\nBen Harris reported that local users could remove set-capability\nattributes from any file visible to them, allowing a denial of\nservice.\n\nCVE-2015-8962\n\nCalvin Owens fouund that removing a SCSI device while it was being\naccessed through the SCSI generic (sg) driver led to a double- free,\npossibly causing a denial of service (crash or memory corruption) or\nprivilege escalation. This could be exploited by local users with\npermision to access a SCSI device node.\n\nCVE-2015-8963\n\nSasha Levin reported that hot-unplugging a CPU resulted in a\nuse-after-free by the performance events (perf) subsystem, possibly\ncausing a denial of service (crash or memory corruption) or privilege\nescalation. This could by exploited by any local user.\n\nCVE-2015-8964\n\nIt was found that the terminal/serial (tty) subsystem did not reliably\nreset the terminal buffer state when the terminal line discipline was\nchanged. This could allow a local user with access to a terminal\ndevice to read sensitive information from kernel memory.\n\nCVE-2016-7097\n\nJan Kara found that changing the POSIX ACL of a file never cleared its\nset-group-ID flag, which should be done if the user changing it is not\na member of the group-owner. In some cases, this would allow the\nuser-owner of an executable to gain the privileges of the group-owner.\n\nCVE-2016-7910\n\nVegard Nossum discovered that a memory allocation failure while\nhandling a read of /proc/diskstats or /proc/partitions could lead to a\nuse-after-free, possibly causing a denial of service (crash or memory\ncorruption) or privilege escalation.\n\nCVE-2016-7911\n\nDmitry Vyukov reported that a race between ioprio_get() and\nioprio_set() system calls could result in a use-after-free, possibly\ncausing a denial of service (crash) or leaking sensitive information.\n\nCVE-2016-7915\n\nBenjamin Tissoires found that HID devices could trigger an out-of-\nbounds memory access in the HID core. A physically present user could\npossibly use this for denial of service (crash) or to leak sensitive\ninformation.\n\nCVE-2016-8399\n\nQidan He reported that the IPv4 ping socket implementation did not\nvalidate the length of packets to be sent. A user with permisson to\nuse ping sockets could cause an out-of-bounds read, possibly resulting\nin a denial of service or information leak. However, on Debian systems\nno users have permission to create ping sockets by default.\n\nCVE-2016-8633\n\nEyal Itkin reported that the IP-over-Firewire driver (firewire-net)\ndid not validate the offset or length in link-layer fragmentation\nheaders. This allowed a remote system connected by Firewire to write\nto memory after a packet buffer, leading to a denial of service\n(crash) or remote code execution.\n\nCVE-2016-8645\n\nMarco Grassi reported that if a socket filter (BPF program) attached\nto a TCP socket truncates or removes the TCP header, this could cause\na denial of service (crash). This was exploitable by any local user.\n\nCVE-2016-8655\n\nPhilip Pettersson found that the implementation of packet sockets\n(AF_PACKET family) had a race condition between enabling a transmit\nring buffer and changing the version of buffers used, which could\nresult in a use-after-free. A local user with the CAP_NET_ADMIN\ncapability could exploit this for privilege escalation.\n\nCVE-2016-9178\n\nAl Viro found that a failure to read data from user memory might lead\nto a information leak on the x86 architecture (amd64 or i386).\n\nCVE-2016-9555\n\nAndrey Konovalov reported that the SCTP implementation does not\nvalidate 'out of the blue' packet chunk lengths early enough. A remote\nsystem able could use this to cause a denial of service (crash) or\nother security impact for systems using SCTP.\n\nCVE-2016-9576, CVE-2016-10088\n\nDmitry Vyukov reported that using splice() with the SCSI generic\ndriver led to kernel memory corruption. Local users with permision to\naccess a SCSI device node could exploit this for privilege escalation.\n\nCVE-2016-9756\n\nDmitry Vyukov reported that KVM for the x86 architecture (amd64 or\ni386) did not correctly handle the failure of certain instructions\nthat require software emulation on older processors. This could be\nexploited by guest systems to leak sensitive information or for denial\nof service (log spam).\n\nCVE-2016-9794\n\nBaozeng Ding reported a race condition in the ALSA (sound) subsystem\nthat could result in a use-after-free. Local users with access to a\nPCM sound device could exploit this for denial of service (crash or\nmemory corruption) or other security impact.\n\nFor Debian 7 'Wheezy', these problems have been fixed in version\n3.2.84-1. This version also includes bug fixes from upstream version\n3.2.84 and updates the PREEMPT_RT featureset to version 3.2.84-rt122.\nFinally, this version adds the option to mitigate security issues in\nthe performance events (perf) subsystem by disabling use by\nunprivileged users. This can be done by setting sysctl\nkernel.perf_event_paranoid=3.\n\nFor Debian 8 'Jessie', these problems have been fixed in version\n3.16.39-1 which will be included in the next point release (8.6).\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.

Android ID:\n A-31349935 (bnc#1014746).\n\n - CVE-2016-8633: drivers/firewire/net.c in the Linux\n kernel, in certain unusual hardware configurations,\n allowed remote attackers to execute arbitrary code via\n crafted fragmented packets (bnc#1008833).\n\n - CVE-2016-8645: The TCP stack in the Linux kernel\n mishandled skb truncation, which allowed local users to\n cause a denial of service (system crash) via a crafted\n application that made sendto system calls, related to\n net/ipv4/tcp_ipv4.c and net/ipv6/tcp_ipv6.c\n (bnc#1009969).\n\n - CVE-2016-9083: drivers/vfio/pci/vfio_pci.c in the Linux\n kernel allowed local users to bypass integer overflow\n checks, and cause a denial of service (memory\n corruption) or have unspecified other impact, by\n leveraging access to a vfio PCI device file for a\n VFIO_DEVICE_SET_IRQS ioctl call, aka a 'state machine\n confusion bug' (bnc#1007197).\n\n - CVE-2016-9084: drivers/vfio/pci/vfio_pci_intrs.c in the\n Linux kernel misuses the kzalloc function, which allowed\n local users to cause a denial of service (integer\n overflow) or have unspecified other impact by leveraging\n access to a vfio PCI device file (bnc#1007197).\n\n - CVE-2016-9756: arch/x86/kvm/emulate.c in the Linux\n kernel did not properly initialize Code Segment (CS) in\n certain error cases, which allowed local users to obtain\n sensitive information from kernel stack memory via a\n crafted application (bnc#1013038).\n\n - CVE-2016-9793: The sock_setsockopt function in\n net/core/sock.c in the Linux kernel mishandled negative\n values of sk_sndbuf and sk_rcvbuf, which allowed local\n users to cause a denial of service (memory corruption\n and system crash) or possibly have unspecified other\n impact by leveraging the CAP_NET_ADMIN capability for a\n crafted setsockopt system call with the (1)\n SO_SNDBUFFORCE or (2) SO_RCVBUFFORCE option (bnc#1013531\n 1013542).\n\n - CVE-2016-9806: Race condition in the netlink_dump\n function in net/netlink/af_netlink.c in the Linux kernel\n allowed local users to cause a denial of service (double\n free) or possibly have unspecified other impact via a\n crafted application that made sendmsg system calls,\n leading to a free operation associated with a new dump\n that started earlier than anticipated (bnc#1013540\n 1017589).\n\n - CVE-2017-2584: arch/x86/kvm/emulate.c in the Linux\n kernel allowed local users to obtain sensitive\n information from kernel memory or cause a denial of\n service (use-after-free) via a crafted application that\n leverages instruction emulation for fxrstor, fxsave,\n sgdt, and sidt (bsc#1019851).\n\n - CVE-2017-2583: Fixed broken emulation of 'MOV SS, null\n selector' (bsc#1020602).\n\n - CVE-2017-5551: Clear SGID bit when setting file\n permissions on tmpfs (bsc#1021258).\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

The following security bugs were fixed :\n\n - CVE-2017-5551: tmpfs: clear S_ISGID when setting posix ACLs (bsc#1021258).\n\n - CVE-2016-10088: The sg implementation in the Linux kernel did not properly restrict write operations in situations where the KERNEL_DS option is set, which allowed local users to read or write to arbitrary kernel memory locations or cause a denial of service (use-after-free) by leveraging access to a /dev/sg device NOTE: this vulnerability existed because of an incomplete fix for CVE-2016-9576 (bnc#1017710).\n\n - CVE-2016-5696: TCP, when using a large Window Size, made it easier for remote attackers to guess sequence numbers and cause a denial of service (connection loss) to persistent TCP connections by repeatedly injecting a TCP RST packet, especially in protocols that use long-lived connections, such as BGP (bnc#989152).\n\n - CVE-2015-1350: The VFS subsystem in the Linux kernel 3.x provided 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-2016-8632: The tipc_msg_build function in net/tipc/msg.c in the Linux kernel did not validate the relationship between the minimum fragment length and the maximum packet size, which allowed local users to gain privileges or cause a denial of service (heap-based buffer overflow) by leveraging the CAP_NET_ADMIN capability (bnc#1008831).\n\n - CVE-2016-8399: An elevation of privilege vulnerability in the kernel networking subsystem could enable a local malicious application to execute arbitrary code within the context of the kernel. This issue is rated as Moderate because it first requires compromising a privileged process and current compiler optimizations restrict access to the vulnerable code. (bnc#1014746).\n\n - CVE-2016-9793: The sock_setsockopt function in net/core/sock.c in the Linux kernel mishandled negative values of sk_sndbuf and sk_rcvbuf, which allowed local users to cause a denial of service (memory corruption and system crash) or possibly have unspecified other impact by leveraging the CAP_NET_ADMIN capability for a crafted setsockopt system call with the (1) SO_SNDBUFFORCE or (2) SO_RCVBUFFORCE option (bnc#1013531).\n\n - CVE-2012-6704: The sock_setsockopt function in net/core/sock.c in the Linux kernel mishandled negative values of sk_sndbuf and sk_rcvbuf, which allowed local users to cause a denial of service (memory corruption and system crash) or possibly have unspecified other impact by leveraging the CAP_NET_ADMIN capability for a crafted setsockopt system call with the (1) SO_SNDBUF or (2) SO_RCVBUF option (bnc#1013542).\n\n - CVE-2016-9756: arch/x86/kvm/emulate.c in the Linux kernel did not properly initialize Code Segment (CS) in certain error cases, which allowed local users to obtain sensitive information from kernel stack memory via a crafted application (bnc#1013038).\n\n - CVE-2016-9685: Multiple memory leaks in error paths in fs/xfs/xfs_attr_list.c in the Linux kernel allowed local users to cause a denial of service (memory consumption) via crafted XFS filesystem operations (bnc#1012832).\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-2013-6368: The KVM subsystem in the Linux kernel allowed local users to gain privileges or cause a denial of service (system crash) via a VAPIC synchronization operation involving a page-end address (bnc#853052).\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, in certain unusual hardware configurations, allowed remote attackers to execute arbitrary code via crafted fragmented packets (bnc#1008833).\n\nThe update package also includes non-security fixes.

"2021-09-24T12:31:35", "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 - A use-after-free vulnerability was found in the kernel's socket recvmmsg subsystem. This may allow remote attackers to corrupt memory and may allow execution of arbitrary code. This corruption takes place during the error handling routines within\n __sys_recvmmsg() function.(CVE-2016-7117)\n\n - A heap-buffer overflow vulnerability was found in the arcmsr_iop_message_xfer() function in 'drivers/scsi/arcmsr/arcmsr_hba.c' file in the Linux kernel through 4.8.2. The function does not restrict a certain length field, which allows local users to gain privileges or cause a denial of service via an ARCMSR_MESSAGE_WRITE_WQBUFFER control code. This can potentially cause kernel heap corruption and arbitrary kernel code execution.(CVE-2016-7425)\n\n - A flaw was found in the Linux kernel's implementation of seq_file where a local attacker could manipulate memory in the put() function pointer. This could lead to memory corruption and possible privileged escalation.(CVE-2016-7910)\n\n - A use-after-free vulnerability in sys_ioprio_get() was found due to get_task_ioprio() accessing the task-i1/4zio_context without holding the task lock and could potentially race with exit_io_context(), leading to a use-after-free.(CVE-2016-7911)\n\n - The xc2028_set_config function in drivers/media/tuners/tuner-xc2028.c in the Linux kernel before 4.6 allows local users to gain privileges or cause a denial of service (use-after-free) via vectors involving omission of the firmware name from a certain data structure. Due to the nature of the flaw, privilege escalation cannot be fully ruled out, although we believe it is unlikely.(CVE-2016-7913)\n\n - The assoc_array_insert_into_terminal_node() function in 'lib/assoc_array.c' in the Linux kernel before 4.5.3 does not check whether a slot is a leaf, which allows local users to obtain sensitive information from kernel memory or cause a denial of service (invalid pointer dereference and out-of-bounds read) via an application that uses associative-array data structures.(CVE-2016-7914)\n\n - The hid_input_field() function in 'drivers/hid/hid-core.c' in the Linux kernel before 4.6 allows physically proximate attackers to obtain sensitive information from kernel memory or cause a denial of service (out-of-bounds read) by connecting a device.(CVE-2016-7915)\n\n - Race condition in the environ_read() function in 'fs/proc/base.c' in the Linux kernel before 4.5.4 allows 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.(CVE-2016-7916)\n\n - A flaw was found in the Linux networking subsystem where a local attacker with CAP_NET_ADMIN capabilities could cause an out-of-bounds memory access by creating a smaller-than-expected ICMP header and sending to its destination via sendto().(CVE-2016-8399)\n\n - Linux kernel built with the Kernel-based Virtual Machine (CONFIG_KVM) support is vulnerable to a null pointer dereference flaw. It could occur on x86 platform, when emulating an undefined instruction. An attacker could use this flaw to crash the host kernel resulting in DoS.(CVE-2016-8630)\n\n - A buffer overflow vulnerability due to a lack of input filtering of incoming fragmented datagrams was found in the IP-over-1394 driver firewire-net in a fragment handling code in the Linux kernel. The vulnerability exists since firewire supported IPv4, i.e. since version 2.6.31 (year 2009) till version v4.9-rc4. A maliciously formed fragment with a respectively large datagram offset would cause a memcpy() past the datagram buffer, which would cause a system panic or possible arbitrary code execution.The flaw requires firewire-net module to be loaded and is remotely exploitable from connected firewire devices, but not over a local network.(CVE-2016-8633)\n\n - It was discovered that the Linux kernel since 3.6-rc1 with 'net.ipv4.tcp_fastopen' set to 1 can hit BUG() statement in tcp_collapse() function after making a number of certain syscalls leading to a possible system crash.(CVE-2016-8645)\n\n - A vulnerability was found in the Linux kernel. An unprivileged local user could trigger oops in shash_async_export() by attempting to force the in-kernel hashing algorithms into decrypting an empty data set.(CVE-2016-8646)\n\n - A flaw was found in the Linux kernel key management subsystem in which a local attacker could crash the kernel or corrupt the stack and additional memory (denial of service) by supplying a specially crafted RSA key. This flaw panics the machine during the verification of the RSA key.(CVE-2016-8650)\n\n - A race condition issue leading to a use-after-free flaw was found in the way the raw packet sockets implementation in the Linux kernel networking subsystem handled synchronization while creating the TPACKET_V3 ring buffer. A local user able to open a raw packet socket (requires the CAP_NET_RAW capability) could use this flaw to elevate their privileges on the system.(CVE-2016-8655)\n\n - A flaw was found in the way the Linux kernel's networking subsystem handled offloaded packets with multiple layers of encapsulation in the GRO (Generic Receive Offload) code path. A remote attacker could use this flaw to trigger unbounded recursion in the kernel that could lead to stack corruption, resulting in a system crash.(CVE-2016-8666)\n\n - A flaw was discovered in the Linux kernel's implementation of VFIO. An attacker issuing an ioctl can create a situation where memory is corrupted and modify memory outside of the expected area. This may overwrite kernel memory and subvert kernel execution.(CVE-2016-9083)\n\n - The use of a kzalloc with an integer multiplication allowed an integer overflow condition to be reached in vfio_pci_intrs.c. This combined with CVE-2016-9083 may allow an attacker to craft an attack and use unallocated memory, potentially crashing the machine.(CVE-2016-9084)\n\n - A flaw was found in the Linux kernel's implementation of the SCTP protocol. A remote attacker could trigger an out-of-bounds read with an offset of up to 64kB potentially causing the system to crash.(CVE-2016-9555)\n\n - It was found that the blk_rq_map_user_iov() function in the Linux kernel's block device implementation did not properly restrict the type of iterator, which could allow a local attacker to read or write to arbitrary kernel memory locations or cause a denial of service (use-after-free) by leveraging write access to a /dev/sg device.(CVE-2016-9576)\n\n - Linux kernel built with the KVM visualization support (CONFIG_KVM), with nested visualization(nVMX) feature enabled(nested=1), is vulnerable to an uncaught exception issue. It could occur if an L2 guest was to throw an exception which is not handled by an L1 guest.(CVE-2016-9588)\n\n - It was discovered that root can gain direct access to an internal keyring, such as '.dns_resolver' in RHEL-7 or '.builtin_trusted_keys' upstream, by joining it as its session keyring. This allows root to bypass module signature verification by adding a new public key of its own devising to the keyring.(CVE-2016-9604)\n\n - A flaw was found in the Linux kernel's implementation of XFS file attributes. Two memory leaks were detected in xfs_attr_shortform_list and xfs_attr3_leaf_list_int when running a docker container backed by xfs/overlay2.\n A dedicated attacker could possible exhaust all memory and create a denial of service situation.(CVE-2016-9685)\n\nNote that Tenable Network Security has extracted the preceding description block directly from the EulerOS security advisory.

CVE-2016-2117: The atl2_probe function in drivers/net/ethernet/atheros/atlx/atl2.c in the Linux kernel incorrectly enabled scatter/gather I/O, which allowed remote attackers to obtain sensitive information from kernel memory by reading packet data (bnc#968697).\n\n - CVE-2016-3070: The trace_writeback_dirty_page implementation in include/trace/events/writeback.h in the Linux kernel improperly interacted with mm/migrate.c, which allowed 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 (bnc#979215).\n\n - CVE-2016-5243: The tipc_nl_compat_link_dump function in net/tipc/netlink_compat.c in the Linux kernel did not properly copy a certain string, which allowed local users to obtain sensitive information from kernel stack memory by reading a Netlink message (bnc#983212).\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-2016-9588: arch/x86/kvm/vmx.c in the Linux kernel mismanages the #BP and #OF exceptions, which allowed guest OS users to cause a denial of service (guest OS crash) by declining to handle an exception thrown by an L2 guest (bnc#1015703).\n\n -

installed that are affected by multiple vulnerabilities as referenced in the ELSA-2017-3534 advisory.\n\n - The bpf_int_jit_compile function in arch/x86/net/bpf_jit_comp.c in the Linux kernel before 4.0.6 allows local users to cause a denial of service (system crash) by creating a packet filter and then loading crafted BPF instructions that trigger late convergence by the JIT compiler. (CVE-2015-4700)\n\n - The sg implementation in the Linux kernel through 4.9 does not properly restrict write operations in situations where the KERNEL_DS option is set, which allows local users to read or write to arbitrary kernel memory locations or cause a denial of service (use-after-free) by leveraging access to a /dev/sg device, related to block/bsg.c and drivers/scsi/sg.c. NOTE: this vulnerability exists because of an incomplete fix for CVE-2016-9576. (CVE-2016-10088)\n\n - An elevation of privilege vulnerability in the kernel networking subsystem could enable a local malicious application to execute arbitrary code within the context of the kernel. This issue is rated as Moderate because it first requires compromising a privileged process and current compiler optimizations restrict access to the vulnerable code. Product: Android. Versions: Kernel-3.10, Kernel-3.18. Android ID:\n A-31349935. (CVE-2016-8399)\n\n - An issue was discovered in the IPv6 protocol specification, related to ICMP Packet Too Big (PTB) messages.\n (The scope of this CVE is all affected IPv6 implementations from all vendors.) The security implications of IP fragmentation have been discussed at length in [RFC6274] and [RFC7739]. An attacker can leverage the generation of IPv6 atomic fragments to trigger the use of fragmentation in an arbitrary IPv6 flow (in scenarios in which actual fragmentation of packets is not needed) and can subsequently perform any type of fragmentation-based attack against legacy IPv6 nodes that do not implement [RFC6946]. That is, employing fragmentation where not actually needed allows for fragmentation-based attack vectors to be employed, unnecessarily. We note that, unfortunately, even nodes that already implement [RFC6946] can be subject to DoS attacks as a result of the generation of IPv6 atomic fragments. Let us assume that Host A is communicating with Host B and that, as a result of the widespread dropping of IPv6 packets that contain extension headers (including fragmentation) [RFC7872], some intermediate node filters fragments between Host B and Host A. If an attacker sends a forged ICMPv6 PTB error message to Host B, reporting an MTU smaller than 1280, this will trigger the generation of IPv6 atomic fragments from that moment on (as required by [RFC2460]). When Host B starts sending IPv6 atomic fragments (in response to the received ICMPv6 PTB error message), these packets will be dropped, since we previously noted that IPv6 packets with extension headers were being dropped between Host B and Host A. Thus, this situation will result in a DoS scenario. Another possible scenario is that in which two BGP peers are employing IPv6 transport and they implement Access Control Lists (ACLs) to drop IPv6 fragments (to avoid control-plane attacks). If the aforementioned BGP peers drop IPv6 fragments but still honor received ICMPv6 PTB error messages, an attacker could easily attack the corresponding peering session by simply sending an ICMPv6 PTB message with a reported MTU smaller than 1280 bytes. Once the attack packet has been sent, the aforementioned routers will themselves be the ones dropping their own traffic. (CVE-2016-10142)\n\n - The sg_ioctl function in drivers/scsi/sg.c in the Linux kernel through 4.10.4 allows local users to cause a denial of service (stack-based buffer overflow) or possibly have unspecified other impact via a large command size in an SG_NEXT_CMD_LEN ioctl call, leading to out-of-bounds write access in the sg_write function. (CVE-2017-7187)\n\n - Race condition in drivers/tty/n_hdlc.c in the Linux kernel through 4.10.1 allows local users to gain privileges or cause a denial of service (double free) by setting the HDLC line discipline. (CVE-2017-2636)\n\n - arch/x86/kvm/vmx.c in the Linux kernel through 4.9 mismanages the #BP and #OF exceptions, which allows guest OS users to cause a denial of service (guest OS crash) by declining to handle an exception thrown by an L2 guest. (CVE-2016-9588)\n\n - The arcmsr_iop_message_xfer function in drivers/scsi/arcmsr/arcmsr_hba.c in the Linux kernel through 4.8.2 does not restrict a certain length field, which allows local users to gain privileges or cause a denial of service (heap-based buffer overflow) via an ARCMSR_MESSAGE_WRITE_WQBUFFER control code. (CVE-2016-7425)\n\n - The (1) pptp_bind and (2) pptp_connect functions in drivers/net/ppp/pptp.c in the Linux kernel through 4.3.3 do not verify an address length, which allows local users to obtain sensitive information from kernel memory and bypass the KASLR protection mechanism via a crafted application. (CVE-2015-8569)\n\n - The x25_negotiate_facilities function in net/x25/x25_facilities.c in the Linux kernel before 4.5.5 does not properly initialize a certain data structure, which allows attackers to obtain sensitive information from kernel stack memory via an X.25 Call Request. (CVE-2016-4580)\n\n - drivers/firewire/net.c in the Linux kernel before 4.8.7, in certain unusual hardware configurations, allows remote attackers to execute arbitrary code via crafted fragmented packets. (CVE-2016-8633)\n\n - The arch_pick_mmap_layout function in arch/x86/mm/mmap.c in the Linux kernel through 4.5.2 does not properly randomize the legacy base address, which makes it easier for local users to defeat the intended restrictions on the ADDR_NO_RANDOMIZE flag, and bypass the ASLR protection mechanism for a setuid or setgid program, by disabling stack-consumption resource limits. (CVE-2016-3672)\n\n - The TCP stack in the Linux kernel before 4.8.10 mishandles skb truncation, which allows local users to cause a denial of service (system crash) via a crafted application that makes sendto system calls, related to net/ipv4/tcp_ipv4.c and net/ipv6/tcp_ipv6.c. (CVE-2016-8645)\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-2016-9178)\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 - The LLC subsystem in the Linux kernel before 4.9.13 does not ensure that a certain destructor exists in required circumstances, which allows local users to cause a denial of service (BUG_ON) or possibly have unspecified other impact via crafted system calls. (CVE-2017-6345)\n\n - The ipv4_pktinfo_prepare function in net/ipv4/ip_sockglue.c in the Linux kernel through 4.9.9 allows attackers to cause a denial of service (system crash) via (1) an application that makes crafted system calls or possibly (2) IPv4 traffic with invalid IP options. (CVE-2017-5970)\n\n - Integer overflow in the sg_start_req function in drivers/scsi/sg.c in the Linux kernel 2.6.x through 4.x before 4.1 allows local users to cause a denial of service or possibly have unspecified other impact via a large iov_count value in a write request.

We note that, unfortunately, even nodes that already implement [RFC6946] can be subject to\n DoS attacks as a result of the generation of IPv6 atomic fragments. Let us assume that Host A is\n communicating with Host B and that, as a result of the widespread dropping of IPv6 packets that contain\n extension headers (including fragmentation) [RFC7872], some intermediate node filters fragments between\n Host B and Host A. If an attacker sends a forged ICMPv6 PTB error message to Host B, reporting an MTU\n smaller than 1280, this will trigger the generation of IPv6 atomic fragments from that moment on (as\n required by [RFC2460]). When Host B starts sending IPv6 atomic fragments (in response to the received\n ICMPv6 PTB error message), these packets will be dropped, since we previously noted that IPv6 packets with\n extension headers were being dropped between Host B and Host A. Thus, this situation will result in a DoS\n scenario. Another possible scenario is that in which two BGP peers are employing IPv6 transport and they\n implement Access Control Lists (ACLs) to drop IPv6 fragments (to avoid control-plane attacks). If the\n aforementioned BGP peers drop IPv6 fragments but still honor received ICMPv6 PTB error messages, an\n attacker could easily attack the corresponding peering session by simply sending an ICMPv6 PTB message\n with a reported MTU smaller than 1280 bytes. Once the attack packet has been sent, the aforementioned\n routers will themselves be the ones dropping their own traffic.

CVE-2016-8399: An elevation of privilege vulnerability\n in the kernel networking subsystem could have enabled a\n local malicious application to execute arbitrary code\n within the context of the kernel bnc#1014746).\n\n - CVE-2016-9793: The sock_setsockopt function in\n net/core/sock.c in the Linux kernel mishandled negative\n values of sk_sndbuf and sk_rcvbuf, which allowed local\n users to cause a denial of service (memory corruption\n and system crash) or possibly have unspecified other\n impact by leveraging the CAP_NET_ADMIN capability for a\n crafted setsockopt system call with the (1)\n SO_SNDBUFFORCE or (2) SO_RCVBUFFORCE option\n (bnc#1013531).\n\n - CVE-2012-6704: The sock_setsockopt function in\n net/core/sock.c in the Linux kernel mishandled negative\n values of sk_sndbuf and sk_rcvbuf, which allowed local\n users to cause a denial of service (memory corruption\n and system crash) or possibly have unspecified other\n impact by leveraging the CAP_NET_ADMIN capability for a\n crafted setsockopt system call with the (1) SO_SNDBUF or\n (2) SO_RCVBUF option (bnc#1013542).\n\n - CVE-2016-9756: arch/x86/kvm/emulate.c in the Linux\n kernel did not properly initialize Code Segment (CS) in\n certain error cases, which allowed local users to obtain\n sensitive information from kernel stack memory via a\n crafted application (bnc#1013038).\n\n - CVE-2016-3841: The IPv6 stack in the Linux kernel\n mishandled options data, which allowed local users to\n gain privileges or cause a denial of service\n (use-after-free and system crash) via a crafted sendmsg\n system call (bnc#992566).\n\n - CVE-2016-9685: Multiple memory leaks in error paths in\n fs/xfs/xfs_attr_list.c in the Linux kernel allowed local\n users to cause a denial of service (memory consumption)\n via crafted XFS filesystem operations (bnc#1012832).\n\n - CVE-2015-1350: The VFS subsystem in the Linux kernel\n provided an incomplete set of requirements for setattr\n operations that underspecifies removing extended\n privilege attributes, which allowed local users to cause\n a denial of service (capability stripping) via a failed\n invocation of a system call, as demonstrated by using\n chown to remove a capability from the ping or Wireshark\n dumpcap program (bnc#914939).\n\n - CVE-2015-8962: Double free vulnerability in the\n sg_common_write function in drivers/scsi/sg.c in the\n Linux kernel allowed local users to gain privileges or\n cause a denial of service (memory corruption and system\n crash) by detaching a device during an SG_IO ioctl call\n (bnc#1010501).\n\n - CVE-2016-9555: The sctp_sf_ootb function in\n net/sctp/sm_statefuns.c in the Linux kernel lacked\n chunk-length checking for the first chunk, which allowed\n remote attackers to cause a denial of service\n (out-of-bounds slab access) or possibly have unspecified\n other impact via crafted SCTP data (bnc#1011685).\n\n - CVE-2016-7910: Use-after-free vulnerability in the\n disk_seqf_stop function in block/genhd.c in the Linux\n kernel allowed local users to gain privileges by\n leveraging the execution of a certain stop operation\n even if the corresponding start operation had failed\n (bnc#1010716).\n\n - CVE-2016-7911: Race condition in the get_task_ioprio\n function in block/ioprio.c in the Linux kernel allowed\n local users to gain privileges or cause a denial of\n service (use-after-free) via a crafted ioprio_get system\n call (bnc#1010711).\n\n - CVE-2015-8964: The tty_set_termios_ldisc function in\n drivers/tty/tty_ldisc.c in the Linux kernel allowed\n local users to obtain sensitive information from kernel\n memory by reading a tty data structure (bnc#1010507).\n\n - CVE-2016-7916: Race condition in the environ_read\n function in fs/proc/base.c in the Linux kernel allowed\n local users to obtain sensitive information from kernel\n memory by reading a /proc/*/environ file during a\n process-setup time interval in which\n environment-variable copying is incomplete\n (bnc#1010467).\n\n - CVE-2016-8646: The hash_accept function in\n crypto/algif_hash.c in the Linux kernel allowed local\n users to cause a denial of service (OOPS) by attempting\n to trigger use of in-kernel hash algorithms for a socket\n that has received zero bytes of data (bnc#1010150).\n\n - CVE-2016-8633: drivers/firewire/net.c in the Linux\n kernel in certain unusual hardware configurations\n allowed remote attackers to execute arbitrary code via\n crafted fragmented packets (bnc#1008833).\n\n - CVE-2016-7042: The proc_keys_show function in\n security/keys/proc.c in the Linux, when the GNU Compiler\n Collection (gcc) stack protector is enabled, used an\n incorrect buffer size for certain timeout data, which\n allowed local users to cause a denial of service (stack\n memory corruption and panic) by reading the /proc/keys\n file (bnc#1004517).\n\n - CVE-2015-8956: The rfcomm_sock_bind function in\n net/bluetooth/rfcomm/sock.c in the Linux kernel allowed\n local users to obtain sensitive information or cause a\n denial of service (NULL pointer dereference) via vectors\n involving a bind system call on a Bluetooth RFCOMM\n 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\n kernel allowed remote attackers to execute arbitrary\n code via vectors involving a recvmmsg system call that\n is mishandled during error processing (bnc#1003077).\n\n - CVE-2016-0823: The pagemap_open function in\n fs/proc/task_mmu.c in the Linux kernel allowed local\n users to obtain sensitive physical-address information\n by reading a pagemap file (bnc#994759).\n\n - CVE-2016-7425: The arcmsr_iop_message_xfer function in\n drivers/scsi/arcmsr/arcmsr_hba.c in the Linux kernel did\n not restrict a certain length field, which allowed local\n users to gain privileges or cause a denial of service\n (heap-based buffer overflow) via an\n ARCMSR_MESSAGE_WRITE_WQBUFFER control code (bnc#999932).\n\n - CVE-2016-6828: The tcp_check_send_head function in\n include/net/tcp.h in the Linux kernel did not properly\n maintain certain SACK state after a failed data copy,\n which allowed local users to cause a denial of service\n (tcp_xmit_retransmit_queue use-after-free and system\n crash) via a crafted SACK option (bnc#994296).\n\nThe update package also includes non-security fixes.

(bsc#1030593)\n\n - CVE-2016-9604: This fixes handling of keyrings starting with '.' in KEYCTL_JOIN_SESSION_KEYRING, which could have allowed local users to manipulate privileged keyrings (bsc#1035576)\n\n - CVE-2017-7616: Incorrect error handling in the set_mempolicy and mbind compat syscalls in mm/mempolicy.c in the Linux kernel allowed local users to obtain sensitive information from uninitialized stack data by triggering failure of a certain bitmap operation. (bnc#1033336).\n\n - CVE-2017-7645: The NFSv2/NFSv3 server in the nfsd subsystem in the Linux kernel allowed remote attackers to cause a denial of service (system crash) via a long RPC reply, related to net/sunrpc/svc.c, fs/nfsd/nfs3xdr.c, and fs/nfsd/nfsxdr.c. (bsc#1034670).\n\n - CVE-2017-7308: The packet_set_ring function in net/packet/af_packet.c in the Linux kernel did not properly validate certain block-size data, which allowed local users to cause a denial of service (overflow) or possibly have unspecified other impact via crafted system calls (bnc#1031579)\n\n - CVE-2017-2671: The ping_unhash function in net/ipv4/ping.c in the Linux kernel was too late in obtaining a certain lock and consequently could not ensure that disconnect function calls are safe, which allowed local users to cause a denial of service (panic) by leveraging access to the protocol value of IPPROTO_ICMP in a socket system call (bnc#1031003)\n\n - CVE-2017-7294: The vmw_surface_define_ioctl function in drivers/gpu/drm/vmwgfx/vmwgfx_surface.c in the Linux kernel did not validate addition of certain levels data, which allowed local users to trigger an integer overflow and out-of-bounds write, and cause a denial of service (system hang or crash) or possibly gain privileges, via a crafted ioctl call for a /dev/dri/renderD* device (bnc#1031440)\n\n - CVE-2017-7261: The vmw_surface_define_ioctl function in drivers/gpu/drm/vmwgfx/vmwgfx_surface.c in the Linux kernel did not check for a zero value of certain levels data, which allowed local users to cause a denial of service (ZERO_SIZE_PTR dereference, and GPF and possibly panic) via a crafted ioctl call for a /dev/dri/renderD* device (bnc#1031052)\n\n - CVE-2017-7187: The sg_ioctl function in drivers/scsi/sg.c in the Linux kernel allowed local users to cause a denial of service (stack-based buffer overflow) or possibly have unspecified other impact via a large command size in an SG_NEXT_CMD_LEN ioctl call, leading to out-of-bounds write access in the sg_write function (bnc#1030213)\n\n - CVE-2016-9588: arch/x86/kvm/vmx.c in the Linux kernel mismanaged the #BP and #OF exceptions, which allowed guest OS users to cause a denial of service (guest OS crash) by declining to handle an exception thrown by an L2 guest (bsc#1015703).\n\n - CVE-2017-5669: The do_shmat function in ipc/shm.c in the Linux kernel did not restrict the address calculated by a certain rounding operation, which allowed local users to map page zero, and consequently bypass a protection mechanism that exists for the mmap system call, by making crafted shmget and shmat system calls in a privileged context (bnc#1026914).\n\n - CVE-2016-10200: Race condition in the L2TPv3 IP Encapsulation feature in the Linux kernel allowed local users to gain privileges or cause a denial of service (use-after-free) by making multiple bind system calls without properly ascertaining whether a socket has the SOCK_ZAPPED status, related to net/l2tp/l2tp_ip.c and net/l2tp/l2tp_ip6.c (bnc#1028415)\n\n - CVE-2016-10208: The ext4_fill_super function in fs/ext4/super.c in the Linux kernel did not properly validate meta block groups, which allowed physically proximate attackers to cause a denial of service (out-of-bounds read and system crash) via a crafted ext4 image (bnc#1023377).\n\n - CVE-2017-5897: The ip6gre_err function in net/ipv6/ip6_gre.c in the Linux kernel allowed remote attackers to have unspecified impact via vectors involving GRE flags in an IPv6 packet, which trigger an out-of-bounds access (bsc#1023762).\n\n - CVE-2017-5986: A race condition in the sctp_wait_for_sndbuf function in net/sctp/socket.c in the Linux kernel allowed local users to cause a denial of service (assertion failure and panic) via a multithreaded application that peels off an association in a certain buffer-full state (bsc#1025235).\n\n - CVE-2017-6074: The dccp_rcv_state_process function in net/dccp/input.c in the Linux kernel mishandled DCCP_PKT_REQUEST packet data structures in the LISTEN state, which allowed local users to obtain root privileges or cause a denial of service (double free) via an application that made an IPV6_RECVPKTINFO setsockopt system call (bnc#1026024)\n\n - CVE-2016-9191: The cgroup offline implementation in the Linux kernel mishandled certain drain operations, which allowed local users to cause a denial of service (system hang) by leveraging access to a container environment for executing a crafted application (bnc#1008842)\n\n - CVE-2017-6348: The hashbin_delete function in net/irda/irqueue.c in the Linux kernel improperly managed lock dropping, which allowed local users to cause a denial of service (deadlock) via crafted operations on IrDA devices (bnc#1027178).\n\n - CVE-2016-10044: The aio_mount function in fs/aio.c in the Linux kernel did not properly restrict execute access, which made it easier for local users to bypass intended SELinux W^X policy restrictions, and consequently gain privileges, via an io_setup system call (bnc#1023992).\n\n - CVE-2016-3070: The trace_writeback_dirty_page implementation in include/trace/events/writeback.h in the Linux kernel improperly interacts with mm/migrate.c, which allowed 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 (bnc#979215).\n\n - CVE-2016-5243: The tipc_nl_compat_link_dump function in net/tipc/netlink_compat.c in the Linux kernel did not properly copy a certain string, which allowed local users to obtain sensitive information from kernel stack memory by reading a Netlink message (bnc#983212).\n\n - CVE-2017-6345: The LLC subsystem in the Linux kernel did not ensure that a certain destructor exists in required circumstances, which allowed local users to cause a denial of service (BUG_ON) or possibly have unspecified other impact via crafted system calls (bnc#1027190)\n\n -
