   An update that fixes three vulnerabilities is now available.


   This update for the Linux Kernel 4.4.21-69 fixes several issues.

   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#1062471).
   - 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).
   - CVE-2017-12762: In drivers/isdn/i4l/isdn_net.c a user-controlled buffer
     was copied into a local buffer of constant size using strcpy without a
     length check which can cause a buffer overflow (bsc#1053150).
