______________________________________________________________________________

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).
