  <summary>Live patch for the Linux Kernel</summary>
<description>
This update contains a kernel live patch for the 3.12.39-47 SUSE Linux Enterprise
Server 12 Kernel, fixing following security issues.

- CVE-2015-3339: A 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. (bsc#939263 bsc#939044)

- CVE-2015-3636: The ping_unhash function in net/ipv4/ping.c in the
  Linux kernel did not initialize a certain list data structure during an
  unhash operation, which allowed local users to gain privileges or cause
  a denial of service (use-after-free and system crash) by leveraging the
  ability to make a SOCK_DGRAM socket system call for the IPPROTO_ICMP
  or IPPROTO_ICMPV6 protocol, and then making a connect system call after
  a disconnect. (bsc#939277)

- CVE-2015-5364/CVE-2015-5366: Two denial of service attacks via a flood
  of UDP packets with invalid checksums were fixed that could be used
  by remote attackers to delay execution. (bsc#939276)

- CVE-2015-1805: The (1) pipe_read and (2) pipe_write implementations in
  fs/pipe.c in the Linux kernel did not properly consider the side effects
  of failed __copy_to_user_inatomic and __copy_from_user_inatomic calls,
  which allowed local users to cause a denial of service (system crash)
  or possibly gain privileges via a crafted application, aka an "I/O vector
  array overrun." (bsc#939270)

- CVE-2015-4700: A BPF Jit optimization flaw could allow local users
  to panic the kernel. (bsc#939273)

- CVE-2015-3331: The __driver_rfc4106_decrypt function in
  arch/x86/crypto/aesni-intel_glue.c in the Linux kernel did not properly
  determine the memory locations used for encrypted data, which allowed
  context-dependent attackers to cause a denial of service (buffer overflow
  and system crash) or possibly execute arbitrary code by triggering a
  crypto API call, as demonstrated by use of a libkcapi test program with
  an AF_ALG(aead) socket. (bsc#939262)

- CVE-2014-8159: The InfiniBand (IB) implementation in the Linux kernel
  did not properly restrict use of User Verbs for registration of memory
  regions, which allowed local users to access arbitrary physical memory
  locations, and consequently cause a denial of service (system crash)
  or gain privileges, by leveraging permissions on a uverbs device under
  /dev/infiniband/. (bsc#939241)
