Live patch for the Linux Kernel (important)

This update contains a kernel live patch for the 3.12.32-33 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-2015-1465: 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. (bsc#939044 bsc#916225)

• 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-2014-9710: The Btrfs implementation in the Linux kernel did not
  ensure that the visible xattr state is consistent with a requested
  replacement, which allowed local users to bypass intended ACL settings
  and gain privileges via standard filesystem operations (1) during an
  xattr-replacement time window, related to a race condition, or (2) after
  an xattr-replacement attempt that fails because the data does not fit.
  (bsc#939260)

• CVE-2014-3687: The sctp_assoc_lookup_asconf_ack function in
  net/sctp/associola.c in the SCTP implementation in the Linux kernel
  allowed remote attackers to cause a denial of service (panic) via
  duplicate ASCONF chunks that trigger an incorrect uncork within the
  side-effect interpreter. (bsc#902349 bsc#939044)

• 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)

• CVE-2014-7822: The implementation of certain splice_write file
  operations in the Linux kernel before 3.16 does not enforce a restriction
  on the maximum size of a single file, which allows local users to cause
  a denial of service (system crash) or possibly have unspecified other
  impact via a crafted splice system call, as demonstrated by use of a
  file descriptor associated with an ext4 filesystem. (bsc#939240)
