The SUSE Linux Enterprise 12 SP1 kernel was updated to 3.12.69 to receive various security and bugfixes. The following security bugs were fixed :

  - 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).

  - CVE-2015-8963: Race condition in kernel/events/core.c in     the Linux kernel allowed local users to gain privileges     or cause a denial of service (use-after-free) by     leveraging incorrect handling of an swevent data     structure during a CPU unplug operation (bnc#1010502).

  - 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).

  - 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, related to block/bsg.c and drivers/scsi/sg.c.
    NOTE: this vulnerability exists because of an incomplete     fix for CVE-2016-9576 (bnc#1017710).

  - 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).

  - 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).

  - CVE-2016-7913: The xc2028_set_config function in     drivers/media/tuners/tuner-xc2028.c in the Linux kernel     allowed 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 (bnc#1010478).

  - CVE-2016-7914: The assoc_array_insert_into_terminal_node     function in lib/assoc_array.c in the Linux kernel did     not check whether a slot is a leaf, which allowed 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, as     demonstrated by the keyutils test suite (bnc#1010475).

  - 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. Product:
    Android. Versions: Kernel-3.10, Kernel-3.18. Android ID:
    A-31349935 (bnc#1014746).

  - 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).

  - CVE-2016-8645: The TCP stack in the Linux kernel     mishandled skb truncation, which allowed local users to     cause a denial of service (system crash) via a crafted     application that made sendto system calls, related to     net/ipv4/tcp_ipv4.c and net/ipv6/tcp_ipv6.c     (bnc#1009969).

  - CVE-2016-9083: drivers/vfio/pci/vfio_pci.c in the Linux     kernel allowed local users to bypass integer overflow     checks, and cause a denial of service (memory     corruption) or have unspecified other impact, by     leveraging access to a vfio PCI device file for a     VFIO_DEVICE_SET_IRQS ioctl call, aka a 'state machine     confusion bug' (bnc#1007197).

  - CVE-2016-9084: drivers/vfio/pci/vfio_pci_intrs.c in the     Linux kernel misuses the kzalloc function, which allowed     local users to cause a denial of service (integer     overflow) or have unspecified other impact by leveraging     access to a vfio PCI device file (bnc#1007197).

  - 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).

  - 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     1013542).

  - CVE-2016-9806: Race condition in the netlink_dump     function in net/netlink/af_netlink.c in the Linux kernel     allowed local users to cause a denial of service (double     free) or possibly have unspecified other impact via a     crafted application that made sendmsg system calls,     leading to a free operation associated with a new dump     that started earlier than anticipated (bnc#1013540     1017589).

  - CVE-2017-2584: arch/x86/kvm/emulate.c in the Linux     kernel allowed local users to obtain sensitive     information from kernel memory or cause a denial of     service (use-after-free) via a crafted application that     leverages instruction emulation for fxrstor, fxsave,     sgdt, and sidt (bsc#1019851).

  - CVE-2017-2583: Fixed broken emulation of 'MOV SS, null     selector' (bsc#1020602).

  - CVE-2017-5551: Clear SGID bit when setting file     permissions on tmpfs (bsc#1021258).

The update package also includes non-security fixes. See advisory for details.

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

Several vulnerabilities have been discovered in the Linux kernel that may lead to a privilege escalation, denial of service or have other impacts.

  - CVE-2016-6786 / CVE-2016-6787     It was discovered that the performance events subsystem     does not properly manage locks during certain     migrations, allowing a local attacker to escalate     privileges. This can be mitigated by disabling     unprivileged use of performance events:sysctl     kernel.perf_event_paranoid=3

  - CVE-2016-8405     Peter Pi of Trend Micro discovered that the frame buffer     video subsystem does not properly check bounds while     copying color maps to userspace, causing a heap buffer     out-of-bounds read, leading to information disclosure.

  - CVE-2016-9191     CAI Qian discovered that reference counting is not     properly handled within proc_sys_readdir in the sysctl     implementation, allowing a local denial of service     (system hang) or possibly privilege escalation.

  - CVE-2017-2583     Xiaohan Zhang reported that KVM for amd64 does not     correctly emulate loading of a null stack selector. This     can be used by a user in a guest VM for denial of     service (on an Intel CPU) or to escalate privileges     within the VM (on an AMD CPU).

  - CVE-2017-2584     Dmitry Vyukov reported that KVM for x86 does not     correctly emulate memory access by the SGDT and SIDT     instructions, which can result in a use-after-free and     information leak.

  - CVE-2017-2596     Dmitry Vyukov reported that KVM leaks page references     when emulating a VMON for a nested hypervisor. This can     be used by a privileged user in a guest VM for denial of     service or possibly to gain privileges in the host.

  - CVE-2017-2618     It was discovered that an off-by-one in the handling of     SELinux attributes in /proc/pid/attr could result in     local denial of service.

  - CVE-2017-5549     It was discovered that the KLSI KL5KUSB105 serial USB     device driver could log the contents of uninitialised     kernel memory, resulting in an information leak.

  - CVE-2017-5551     Jan Kara found that changing the POSIX ACL of a file on     tmpfs never cleared its set-group-ID flag, which should     be done if the user changing it is not a member of the     group-owner. In some cases, this would allow the     user-owner of an executable to gain the privileges of     the group-owner.

  - CVE-2017-5897     Andrey Konovalov discovered an out-of-bounds read flaw     in the ip6gre_err function in the IPv6 networking code.

  - CVE-2017-5970     Andrey Konovalov discovered a denial-of-service flaw in     the IPv4 networking code. This can be triggered by a     local or remote attacker if a local UDP or raw socket     has the IP_RETOPTS option enabled.

  - CVE-2017-6001     Di Shen discovered a race condition between concurrent     calls to the performance events subsystem, allowing a     local attacker to escalate privileges. This flaw exists     because of an incomplete fix of CVE-2016-6786. This can     be mitigated by disabling unprivileged use of     performance events: sysctl kernel.perf_event_paranoid=3

  - CVE-2017-6074     Andrey Konovalov discovered a use-after-free     vulnerability in the DCCP networking code, which could     result in denial of service or local privilege     escalation. On systems that do not already have the dccp     module loaded, this can be mitigated by disabling     it:echo >> /etc/modprobe.d/disable-dccp.conf install     dccp false
