______________________________________________________________________________

   An update that solves 7 vulnerabilities and has 7 fixes is
   now available.

Description:


   The openSUSE 13.2 kernel was updated to receive various security and
   bugfixes.

   Following security bugs were fixed:
   * CVE-2015-3290: arch/x86/entry/entry_64.S in the Linux kernel on the
     x86_64 platform improperly relied on espfix64 during nested NMI
     processing, which allowed local users to gain privileges by triggering
     an NMI within a certain instruction window (bnc#937969)
   * CVE-2015-0272: It was reported that it's possible to craft a Router
     Advertisement message which will bring the receiver in a state where new
     IPv6 connections will not be accepted until correct Router Advertisement
     message received. (bsc#944296).
   * 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-2015-1333: Memory leak in the __key_link_end function in
     security/keys/keyring.c in the Linux kernel allowed local users to cause
     a denial of service (memory consumption) via many add_key system calls
     that refer to existing keys. (bsc#938645)
   * CVE-2015-5707: Integer overflow in the sg_start_req function in
     drivers/scsi/sg.c in the Linux kernel allowed local users to cause a
     denial of service or possibly have unspecified other impact via a large
     iov_count value in a write request. (bsc#940338)
   * CVE-2015-2925: An attacker could potentially break out of a namespace
     or container, depending on if he had specific rights in these
      containers. (bsc#926238).
   * CVE-2015-7872: A vulnerability in keyrings garbage collector allowed a
     local user to trigger an oops was found, caused by using request_key()
     or keyctl request2. (bsc#951440)


   The following non-security bugs were fixed:
   - input: evdev - do not report errors form flush() (bsc#939834).
   - NFSv4: Recovery of recalled read delegations is broken (bsc#942178).
   - apparmor: temporary work around for bug while unloading policy
     (boo#941867).
   - config/x86_64/ec2: Align CONFIG_STRICT_DEVMEM CONFIG_STRICT_DEVMEM is
     enabled in every other kernel flavor, so enable it for x86_64/ec2 as
     well.
   - kernel-obs-build: add btrfs to initrd This is needed for kiwi builds.
   - mmc: card: Do not access RPMB partitions for normal read/write
     (bnc#941104).
   - netback: coalesce (guest) RX SKBs as needed (bsc#919154).
   - rpm/kernel-obs-build.spec.in: Add virtio_rng to the initrd. This allows
     to feed some randomness to the OBS workers.
   - xfs: Fix file type directory corruption for btree directories
     (bsc#941305).
   - xfs: ensure buffer types are set correctly (bsc#941305).
   - xfs: inode unlink does not set AGI buffer type (bsc#941305).
   - xfs: set buf types when converting extent formats (bsc#941305).
   - xfs: set superblock buffer type correctly (bsc#941305).
   - xhci: Add spurious wakeup quirk for LynxPoint-LP controllers     (bnc#951195).
