    Description:

    This update for the Linux Kernel 3.12.61-52_80 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).
