"This update for the Linux Kernel 3.12.69-60_64_32 fixes one issue. The
following security bugs were fixed :

  - CVE-2017-15274: security/keys/keyctl.c in the Linux
    kernel did not consider the case of a NULL payload in
    conjunction with a nonzero length value, which allowed
    local users to cause a denial of service (NULL pointer
    dereference and OOPS) via a crafted add_key or keyctl
    system call (bsc#1045327).

  - CVE-2017-1000251: The native Bluetooth stack in the
    Linux Kernel (BlueZ) was vulnerable to a stack overflow
    vulnerability in the processing of L2CAP configuration
    responses resulting in Remote code execution in kernel
    space (bsc#1057950).

Note that Tenable Network Security has extracted the preceding
description block directly from the SUSE security advisory. Tenable
has attempted to automatically clean and format it as much as possible
without introducing additional issues."
