"This update for the Linux Kernel 3.12.74-60_64_57 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).

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.");
