  package(s) announced via the referenced advisory.");

  script_tag(name:"insight", value:"The SUSE Linux Enterprise 12 kernel was updated to 3.12.38 to receive
  various security and bugfixes.

  This update contains the following feature enablements:

  - The remote block device (rbd) and ceph drivers have been enabled and are
  now supported. (FATE#318350) These can be used e.g. for accessing the
  SUSE Enterprise Storage product services.

  - Support for Intel Select Bay trail CPUs has been added. (FATE#316038)

  The following security issues were fixed:

  - CVE-2014-9419: The __switch_to function in arch/x86/kernel/process_64.c
  in the Linux kernel through 3.18.1 did not ensure that Thread Local
  Storage (TLS) descriptors were loaded before proceeding with other
  steps, which made it easier for local users to bypass the ASLR
  protection mechanism via a crafted application that reads a TLS base
  address (bnc#911326).

  - CVE-2014-7822: A flaw was found in the way the Linux kernels splice()
  system call validated its parameters. On certain file systems, a local,
  unprivileged user could have used this flaw to write past the maximum
  file size, and thus crash the system.

  - CVE-2014-8160: The connection tracking module could be bypassed if a
  specific protocol module was not loaded, e.g. allowing SCTP traffic
  while the firewall should have filtered it.

  - CVE-2014-9584: The parse_rock_ridge_inode_internal function in
  fs/isofs/rock.c in the Linux kernel before 3.18.2 did not validate a
  length value in the Extensions Reference (ER) System Use Field, which
  allowed local users to obtain sensitive information from kernel memory
  via a crafted iso9660 image (bnc#912654).

  The following non-security bugs were fixed:

  - audit: Allow login in non-init namespaces (bnc#916107).

  - btrfs: avoid unnecessary switch of path locks to blocking mode.

  - btrfs: fix directory inconsistency after fsync log replay (bnc#915425).

  - btrfs: fix fsync log replay for inodes with a mix of regular refs and
  extrefs (bnc#915425).

  - btrfs: fix fsync race leading to ordered extent memory leaks
  (bnc#917128).

  - btrfs: fix fsync when extend references are added to an inode
  (bnc#915425).

  - btrfs: fix missing error handler if submitting re-read bio fails.

  - btrfs: fix race between transaction commit and empty block group removal
  (bnc#915550).

  - btrfs: fix scrub race leading to use-after-free (bnc#915456).

  - btrfs: fix setup_leaf_for_split() to avoid leaf corruption (bnc#915454).

  - btrfs: improve free space cache management and space allocation.

  - btrfs: make btrfs_search_forward return with nodes unlocked.

  - btrfs:  ...
