   An update that fixes two vulnerabilities is now available.

Description:

   This update for the Linux Kernel 3.12.74-60_64_51 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).
