______________________________________________________________________________

   An update that solves 12 vulnerabilities and has 19 fixes
   is now available.

Description:

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

   The following security bugs were fixed:

   - CVE-2015-8956: The rfcomm_sock_bind function in
     net/bluetooth/rfcomm/sock.c in the Linux kernel allowed local users to
     obtain sensitive information or cause a denial of service (NULL pointer
      dereference) via vectors involving a bind system call on a Bluetooth
      RFCOMM socket (bnc#1003925).
   - CVE-2016-5195: A local privilege escalation using MAP_PRIVATE was fixed,
     which is reportedly exploited in the wild (bsc#1004418).
   - CVE-2016-8658: Stack-based buffer overflow in the
     brcmf_cfg80211_start_ap function in
     drivers/net/wireless/broadcom/brcm80211/brcmfmac/cfg80211.c in the Linux
     kernel allowed local users to cause a denial of service (system crash)
     or possibly have unspecified other impact via a long SSID Information
      Element in a command to a Netlink socket (bnc#1004462).
   - CVE-2016-7117: Use-after-free vulnerability in the __sys_recvmmsg
     function in net/socket.c in the Linux kernel allowed remote attackers to
     execute arbitrary code via vectors involving a recvmmsg system call that
     is mishandled during error processing (bnc#1003077).
   - CVE-2016-0823: The pagemap_open function in fs/proc/task_mmu.c in the
     Linux kernel before 3.19.3, as used in Android 6.0.1 before 2016-03-01,
     allowed local users to obtain sensitive physical-address information by
     reading a pagemap file, aka Android internal bug 25739721 (bnc#994759).
   - CVE-2016-7425: The arcmsr_iop_message_xfer function in
     drivers/scsi/arcmsr/arcmsr_hba.c in the Linux kernel did not restrict a
     certain length field, which allowed local users to gain privileges
     or cause a denial of service (heap-based buffer overflow) via an
      ARCMSR_MESSAGE_WRITE_WQBUFFER control code (bnc#999932).
   - CVE-2016-6327: drivers/infiniband/ulp/srpt/ib_srpt.c in the Linux kernel
     allowed local users to cause a denial of service (NULL pointer
     dereference and system crash) by using an ABORT_TASK command to abort a
     device write operation (bnc#994748).
   - CVE-2016-6828: The tcp_check_send_head function in include/net/tcp.h in
     the Linux kernel did not properly maintain certain SACK state after a
     failed data copy, which allowed local users to cause a denial of service
     (tcp_xmit_retransmit_queue use-after-free and system crash) via a
     crafted SACK option (bnc#994296).
   - CVE-2016-5696: net/ipv4/tcp_input.c in the Linux kernel did not properly
     determine the rate of challenge ACK segments, which made it easier for
     man-in-the-middle attackers to hijack TCP sessions via a blind in-window
     attack (bnc#989152)
   - CVE-2016-6480: Race condition in the ioctl_send_fib function in
     drivers/scsi/aacraid/commctrl.c in the Linux kernel allowed local users
     to cause a denial of service (out-of-bounds access or system crash) by
     changing a certain size value, aka a "double fetch" vulnerability
     (bnc#991608).
   - CVE-2015-7513: arch/x86/kvm/x86.c in the Linux kernel did not reset the
     PIT counter values during state restoration, which allowed guest OS
     users to cause a denial of service (divide-by-zero error and host OS
     crash) via a zero value, related to the kvm_vm_ioctl_set_pit and
     kvm_vm_ioctl_set_pit2 functions (bnc#960689).
   - CVE-2016-1237: nfsd in the Linux kernel allowed local users to bypass
     intended file-permission restrictions by setting a POSIX ACL, related to
     nfs2acl.c, nfs3acl.c, and nfs4acl.c (bnc#986570).

   The following non-security bugs were fixed:

   - AF_VSOCK: Shrink the area influenced by prepare_to_wait (bsc#994520).

     bug#881008 (bnc#978094)

   - Update patches.fixes/0001-posix_acl-Add-set_posix_acl.patch (bsc#986570
     CVE#2016-1237).

     (bsc#1000287).
   - arm64: Honor __GFP_ZERO in dma allocations (bsc#1004045).
   - arm64: __clear_user: handle exceptions on strb (bsc#994752).
   - arm64: dma-mapping: always clear allocated buffers (bsc#1004045).
   - arm64: perf: reject groups spanning multiple HW PMUs (bsc#1003931).
   - blkfront: fix an error path memory leak (luckily none so far).
   - blktap2: eliminate deadlock potential from shutdown path (bsc#909994).
   - blktap2: eliminate race from deferred work queue handling (bsc#911687).
   - btrfs: ensure that file descriptor used with subvol ioctls is a dir
     (bsc#999600).
   - cdc-acm: added sanity checking for probe() (bsc#993891).
