  script_tag(name:"insight", value:"This update for the Linux Kernel 3.12.44-52_18 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-2016-1583: The ecryptfs_privileged_open function in
 fs/ecryptfs/kthread.c in the Linux kernel allowed local users to gain
 privileges or cause a denial of service (stack memory consumption) via
 vectors involving crafted mmap calls for /proc pathnames, leading to
 recursive pagefault handling (bsc#983144).
- 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).");
