This update for the Linux Kernel 3.12.60-52_60 fixes several issues.

The following security issues were fixed:

• CVE-2017-16939: The XFRM dump policy implementation in
  net/xfrm/xfrm_user.c allowed local users to gain privileges or cause a
  denial of service (use-after-free) via a crafted SO_RCVBUF setsockopt
  system call in conjunction with XFRM_MSG_GETPOLICY Netlink messages
  (bsc#1069708).
• CVE-2017-10661: Race condition in fs/timerfd.c allowed local users to
  gain privileges or cause a denial of service (list corruption or
  use-after-free) via simultaneous file-descriptor operations that
  leverage improper might_cancel queueing (bsc#1053153).
