Security update for the Linux Kernel (important)

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

Following security bugs were fixed:

• CVE-2015-3290: A flaw was found in the way the Linux kernels nested NMI
  handler and espfix64 functionalities interacted during NMI processing. A
  local, unprivileged user could use this flaw to crash the system or,
  potentially, escalate their privileges on the system.
• CVE-2015-3212: A race condition flaw was found in the way the Linux
  kernels SCTP implementation handled Address Configuration lists when
  performing Address Configuration Change (ASCONF). A local attacker could
  use this flaw to crash the system via a race condition triggered by
  setting certain ASCONF options on a socket.
• CVE-2015-5364: A remote denial of service (hang) via UDP flood with
  incorrect package checksums was fixed. (bsc#936831).
• CVE-2015-5366: A remote denial of service (unexpected error returns) via
  UDP flood with incorrect package checksums was fixed. (bsc#936831).
• CVE-2015-4700: A local user could have created a bad instruction in the
  JIT processed BPF code, leading to a kernel crash (bnc#935705).
• CVE-2015-1420: Race condition in the handle_to_path function in
  fs/fhandle.c in the Linux kernel allowed local users to bypass intended
  size restrictions and trigger read operations on additional memory
  locations by changing the handle_bytes value of a file handle during the
  execution of this function (bnc#915517).
• CVE-2015-4692: The kvm_apic_has_events function in arch/x86/kvm/lapic.h
  in the Linux kernel allowed local users to cause a denial of service
  (NULL pointer dereference and system crash) or possibly have unspecified
  other impact by leveraging /dev/kvm access for an ioctl call
  (bnc#935542).
• CVE-2015-4167 CVE-2014-9728 CVE-2014-9730 CVE-2014-9729 CVE-2014-9731:
  Various problems in the UDF filesystem were fixed that could lead to
  crashes when mounting prepared udf filesystems.
• CVE-2015-4002: drivers/staging/ozwpan/ozusbsvc1.c in the OZWPAN driver
  in the Linux kernel did not ensure that certain length values are
  sufficiently large, which allowed remote attackers to cause a denial of
  service (system crash or large loop) or possibly execute arbitrary code
  via a crafted packet, related to the (1) oz_usb_rx and (2)
  oz_usb_handle_ep_data functions (bnc#933934).
• CVE-2015-4003: The oz_usb_handle_ep_data function in
  drivers/staging/ozwpan/ozusbsvc1.c in the OZWPAN driver in the Linux
  kernel allowed remote attackers to cause a denial of service
  (divide-by-zero error and system crash) via a crafted packet
  (bnc#933934).
• CVE-2015-4001: Integer signedness error in the oz_hcd_get_desc_cnf
  function in drivers/staging/ozwpan/ozhcd.c in the OZWPAN driver in the
  Linux kernel allowed remote attackers to cause a denial of service
  (system crash) or possibly execute arbitrary code via a crafted packet
  (bnc#933934).
• CVE-2015-4036: A potential memory corruption in vhost/scsi was fixed.
• CVE-2015-2922: The ndisc_router_discovery function in net/ipv6/ndisc.c
  in the Neighbor Discovery (ND) protocol implementation in the IPv6 stack
  in the Linux kernel allowed remote attackers to reconfigure a hop-limit
  setting via a small hop_limit value in a Router Advertisement (RA)
  message (bnc#922583).
• CVE-2015-3636: It was found that the Linux kernels ping socket
  implementation did not properly handle socket unhashing during spurious
  disconnects, which could lead to a use-after-free flaw. On x86-64
  architecture systems, a local user able to create ping sockets could use
  this flaw to crash the system. On non-x86-64 architecture systems, a
  local user able to create ping sockets could use this flaw to escalate
  their privileges on the system.
• CVE-2015-2041: net/llc/sysctl_net_llc.c in the Linux kernel used an
  incorrect data type in a sysctl table, which allowed local users to
  obtain potentially sensitive information from kernel memory or possibly
  have unspecified other impact by accessing a sysctl entry (bnc#919007).
• CVE-2015-3339: Race condition in the prepare_binprm function in
  fs/exec.c in the Linux kernel allowed local users to gain privileges by
  executing a setuid program at a time instant when a chown to root is in
  progress, and the ownership is changed but the setuid bit is not yet
  stripped.
• CVE-2015-1465: The IPv4 implementation in the Linux kernel did not
  properly consider the length of the Read-Copy Update (RCU) grace period
  for redirecting lookups in the absence of caching, which allowed remote
  attackers to cause a denial of service (memory consumption or system
  crash) via a flood of packets (bnc#916225).
