  script_tag(name:"insight", value:"The SUSE Linux Enterprise 12 kernel was updated to 3.12.36 to receive various security and bugfixes.

Following security bugs were fixed:
- CVE-2014-8559: The d_walk function in fs/dcache.c in the Linux kernel
 through 3.17.2 did not properly maintain the semantics of rename_lock,
 which allowed local users to cause a denial of service (deadlock and
 system hang) via a crafted application (bnc#903640).
- CVE-2014-9420: The rock_continue function in fs/isofs/rock.c in the
 Linux kernel through 3.18.1 did not restrict the number of Rock Ridge
 continuation entries, which allowed local users to cause a denial of
 service (infinite loop, and system crash or hang) via a crafted iso9660
 image (bnc#906545 911325).
- CVE-2014-3690: arch/x86/kvm/vmx.c in the KVM subsystem in the Linux
 kernel before 3.17.2 on Intel processors did not ensure that the value
 in the CR4 control register remained the same after a VM entry, which
 allowed host OS users to kill arbitrary processes or cause a denial of
 service (system disruption) by leveraging /dev/kvm access, as
 demonstrated by PR_SET_TSC prctl calls within a modified copy of QEMU
 (bnc#902232).
- CVE-2014-3687: The sctp_assoc_lookup_asconf_ack function in
 net/sctp/associola.c in the SCTP implementation in the Linux kernel
 through 3.17.2 allowed remote attackers to cause a denial of service
 (panic) via duplicate ASCONF chunks that triggered an incorrect uncork
 within the side-effect interpreter (bnc#902349).
- CVE-2014-9585: The vdso_addr function in arch/x86/vdso/vma.c in the
 Linux kernel through 3.18.2 did not properly choose memory locations for
 the vDSO area, which made it easier for local users to bypass the ASLR
 protection mechanism by guessing a location at the end of a PMD
 (bnc#912705).

The following non-security bugs were fixed:
- ACPI idle: permit sparse C-state sub-state numbers (bnc#907969).
- ALSA: hda - verify pin:converter connection on unsol event for HSW and
 VLV.
- ALSA: hda - verify pin:cvt connection on preparing a stream for Intel
 HDMI codec.
- ALSA: hda/hdmi - apply Valleyview fix-ups to Cherryview display codec.
- ALSA: hda_intel: Add Device IDs for Intel Sunrise Point PCH.
- ALSA: hda_intel: Add DeviceIDs for Sunrise Point-LP.
- Btrfs: Disable
 patches.suse/Btrfs-fix-abnormal-long-waiting-in-fsync.patch (bnc#910697)
 because it needs to be revisited due partial msync behavior.
- Btrfs: Fix misuse of chunk mutex (bnc#912514).
- Btrfs: always clear a block group node when removing it from the tree
 (bnc#912514).
- Btrfs: collect only the necessary ordered extents on ranged fsync
 (bnc#912946).
- Btrfs: do not access non-existent key when csum tree is empty.
- Btrfs: do not delay inode ref updates during log replay.
- Btrfs: do not ignore log btree writeback errors (bnc#912946).
- Btrfs: ensure btrfs_prev_leaf does not miss 1 item.
- Btrfs: ensure deletion from pinned_chunks list is protected ... [Please see the references for more information on the vulnerabilities]");
