    security and bugfixes.

    The following security bugs were fixed:

    - CVE-2017-1000405: A bug in the THP CoW support could be used by local
    attackers to corrupt memory of other processes and cause them to crash
    (bnc#1069496).
    - CVE-2017-16939: The XFRM dump policy implementation in
    net/xfrm/xfrm_user.c in the Linux kernel 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 (bnc#1069702).

    The following non-security bugs were fixed:

    Fix a build issue on ppc64le systems (bsc#1070805)
