   An update that fixes 5 vulnerabilities is now available.

Description:

   This update for the Linux Kernel 3.12.59-60_41 fixes the several issues.

   These security issues were fixed:
   - CVE-2016-4470: The key_reject_and_link function in security/keys/key.c
     in the Linux kernel did not ensure that a certain data structure is
     initialized, which allowed local users to cause a denial of service
     (system crash) via vectors involving a crafted keyctl request2 command
     (bsc#984764).
   - CVE-2016-4565: The InfiniBand (aka IB) stack in the Linux kernel
     incorrectly relied on the write system call, which allowed local users
     to cause a denial of service (kernel memory write operation) or possibly
     have unspecified other impact via a uAPI interface (bsc#980883).
   - CVE-2016-0758: Integer overflow in lib/asn1_decoder.c in the Linux
     kernel allowed local users to gain privileges via crafted ASN.1 data
     (bsc#980856).
   - CVE-2016-2053: The asn1_ber_decoder function in lib/asn1_decoder.c in
     the Linux kernel allowed attackers to cause a denial of service (panic)
     via an ASN.1 BER file that lacks a public key, leading to mishandling by
     the public_key_verify_signature function in
     crypto/asymmetric_keys/public_key.c (bsc#979074).
