  script_tag(name:"insight", value:"The SUSE Linux Enterprise 12 kernel was updated to 3.12.48-52.27 to
receive various security and bugfixes.

Following security bugs were fixed:
* CVE-2015-7613: A flaw was found in the Linux kernel IPC code that could
 lead to arbitrary code execution. The ipc_addid() function initialized
 a shared object that has unset uid/gid values. Since the fields are not
 initialized, the check can falsely succeed. (bsc#948536)
* CVE-2015-5156: When a guests KVM network devices is in a bridge
 configuration the kernel can create a situation in which packets are
 fragmented in an unexpected fashion. The GRO functionality can create
 a situation in which multiple SKB's are chained together in a single
 packets fraglist (by design). (bsc#940776)
* CVE-2015-5157: arch/x86/entry/entry_64.S in the Linux kernel before
 4.1.6 on the x86_64 platform mishandles IRET faults in processing NMIs
 that occurred during userspace execution, which might allow local
 users to gain privileges by triggering an NMI (bsc#938706).
* CVE-2015-6252: A flaw was found in the way the Linux kernel's vhost
 driver treated userspace provided log file descriptor when processing
 the VHOST_SET_LOG_FD ioctl command. The file descriptor was never
 released and continued to consume kernel memory. A privileged local
 user with access to the /dev/vhost-net files could use this flaw to
 create a denial-of-service attack (bsc#942367).
* CVE-2015-5697: The get_bitmap_file function in drivers/md/md.c in the
 Linux kernel before 4.1.6 does not initialize a certain bitmap data
 structure, which allows local users to obtain sensitive information
 from kernel memory via a GET_BITMAP_FILE ioctl call. (bnc#939994)
* CVE-2015-6937: A NULL pointer dereference flaw was found in the
 Reliable Datagram Sockets (RDS) implementation allowing a local user to
 cause system DoS. A verification was missing that the underlying
 transport exists when a connection was created. (bsc#945825)
* CVE-2015-5283: A NULL pointer dereference flaw was found in SCTP
 implementation allowing a local user to cause system DoS. Creation of
 multiple sockets in parallel when system doesn't have SCTP module
 loaded can lead to kernel panic. (bsc#947155)

The following non-security bugs were fixed:
- ALSA: hda - Abort the probe without i915 binding for HSW/BDW
 (bsc#936556).
- Btrfs: Backport subvolume mount option handling (bsc#934962)
- Btrfs: Handle unaligned length in extent_same (bsc#937609).
- Btrfs: advertise which crc32c implementation is being used on mount
 (bsc#946057).
- Btrfs: allow mounting btrfs subvolumes with different ro/rw options.
- Btrfs: check if previous transaction aborted to avoid fs corruption
 (bnc#942509).
- Btrfs: clean up error handling in mount_subvol() (bsc#934962).
- Btrfs: cleanup orphans while looking up default subvolume (bsc#914818).
- Btrfs: do not update mtime/ctime on deduped inodes (bsc#937616).
- Btrfs: fail on ... [Please see the references for more information on the vulnerabilities]");
