This update for the Linux Kernel 3.12.51-60_20 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-2016-1583: 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-2015-8019: The skb_copy_and_csum_datagram_iovec function in
    net/core/datagram.c in the Linux kernel did not accept a length
    argument, which allowed local users to cause a denial of service (memory
    corruption) or possibly have unspecified other impact via a write system
    call followed by a recvmsg system call (bsc#979078).
  • 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). This non-security issue
    was fixed:
  • bsc#973570: The fix for CVE-2013-7446 introduced a bug that could have
    possibly lead to a softlockup.
