______________________________________________________________________________

   An update that solves 12 vulnerabilities and has 8 fixes is
   now available.

Description:



   The openSUSE 13.2 kernel was updated 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-2016-7042: The proc_keys_show function in security/keys/proc.c in
     the Linux kernel through 4.8.2, 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).
   - 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-2016-7916: 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).
   - 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).
   - 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).
   - CVE-2016-8655: A race condition in the af_packet packet_set_ring
     function could be used by local attackers to crash the kernel or gain
     privileges (bsc#1012754).
   - CVE-2016-9555: The sctp_sf_ootb function in net/sctp/sm_statefuns.c in
     the Linux kernel lacks 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).

   The following non-security bugs were fixed:

   - bna: Add synchronization for tx ring (bsc#993739).
   - bonding: set carrier off for devices created through netlink
     (bsc#999577).
   - btrfs: fix extent tree corruption due to relocation (bsc#990384).
   - introduce NETIF_F_GSO_ENCAP_ALL helper mask (bsc#1001486).
   - ipv6: send NEWLINK on RA managed/otherconf changes (bsc#934067).
   - ipv6: send only one NEWLINK when RA causes changes (bsc#934067).
   - tunnels: Remove encapsulation offloads on decap (bsc#1001486).
   - usbhid: add ATEN CS962 to list of quirky devices (bsc#1007615).
   - vmxnet3: Wake queue from reset work (bsc#999907).
