An update that solves seven vulnerabilities and has one security fix can now be installed.

Description:

This update for the Linux Kernel 3.12.55-52_45 fixes several issues.

The following security bugs 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). - CVE-2015-8816: The hub_activate function in drivers/usb/core/hub.c in the Linux kernel did not properly maintain a hub-interface data structure, which allowed physically proximate attackers to cause a denial of service (invalid memory access and system crash) or possibly have unspecified other impact by unplugging a USB hub device (bsc#979064). - CVE-2016-3134: The netfilter subsystem in the Linux kernel did not validate certain offset fields, which allowed local users to gain privileges or cause a denial of service (heap memory corruption) via an IPT_SO_SET_REPLACE setsockopt call (bsc#971793). - CVE-2013-7446: Use-after-free vulnerability in net/unix/af_unix.c in the Linux kernel allowed local users to bypass intended AF_UNIX socket permissions or cause a denial of service (panic) via crafted epoll_ctl calls (bsc#973570, bsc#955837).
