  script_tag(name:"insight", value:"The SUSE Linux Enterprise 12 kernel was updated to 3.12.51 to receive
  various security and bugfixes.

  The following security bugs were fixed:

  - CVE-2015-7799: The slhc_init function in drivers/net/slip/slhc.c in the
  Linux kernel did not ensure that certain slot numbers were valid, which
  allowed local users to cause a denial of service (NULL pointer
  dereference and system crash) via a crafted PPPIOCSMAXCID ioctl call
  (bnc#949936).

  - CVE-2015-5283: The sctp_init function in net/sctp/protocol.c in the
  Linux kernel had an incorrect sequence of protocol-initialization steps,
  which allowed local users to cause a denial of service (panic or memory
  corruption) by creating SCTP sockets before all of the steps have
  finished (bnc#947155).

  - CVE-2015-2925: The prepend_path function in fs/dcache.c in the Linux
  kernel did not properly handle rename actions inside a bind mount, which
  allowed local users to bypass an intended container protection mechanism
  by renaming a directory, related to a 'double-chroot attack (bnc#926238).

  - CVE-2015-8104: The KVM subsystem in the Linux kernel allowed guest OS
  users to cause a denial of service (host OS panic or hang) by triggering
  many #DB (aka Debug) exceptions, related to svm.c (bnc#954404).

  - CVE-2015-5307: The KVM subsystem in the Linux kernel allowed guest OS
  users to cause a denial of service (host OS panic or hang) by triggering
  many #AC (aka Alignment Check) exceptions, related to svm.c and vmx.c
  (bnc#953527).

  - CVE-2015-7990: RDS: There was no verification that an underlying
  transport exists when creating a connection, causing usage of a NULL
  pointer (bsc#952384).

  - CVE-2015-7872: The key_gc_unused_keys function in security/keys/gc.c in
  the Linux kernel allowed local users to cause a denial of service (OOPS)
  via crafted keyctl commands (bnc#951440).

  - CVE-2015-0272: Missing checks allowed remote attackers to cause a denial
  of service (IPv6 traffic disruption) via a crafted MTU value in an IPv6
  Router Advertisement (RA) message, a different vulnerability than
  CVE-2015-8215 (bnc#944296).

  The following non-security bugs were fixed:

  - ALSA: hda - Disable 64bit address for Creative HDA controllers
  (bnc#814440).

  - Add PCI IDs of Intel Sunrise Point-H SATA Controller S232/236
  (bsc#953796).

  - Btrfs: fix file corruption and data loss after cloning inline extents
  (bnc#956053).

  - Btrfs: fix truncation of compressed and inlined extents (bnc#956053).

  - Disable some ppc64le netfilter modules to restore the kabi (bsc#951546)

  - Fix regression .
