    An update that fixes three vulnerabilities is now available.

    Description:

    This update for the Linux Kernel 3.12.74-60_64_48 fixes several issues.

    The following security bugs were fixed:

    - CVE-2017-7533: A bug in inotify code allowed local users to escalate
    privilege (bsc#1050751).
    - CVE-2017-9242: The __ip6_append_data function in net/ipv6/ip6_output.c
    in the Linux kernel is too late in checking whether an overwrite of an
    skb data structure may occur, which allowed local users to cause a
    denial of service (system crash) via crafted system calls (bsc#1042892).
    - CVE-2017-8890: The inet_csk_clone_lock function in
    net/ipv4/inet_connection_sock.c in the Linux kernel allowed attackers to
    cause a denial of service (double free) or possibly have unspecified
    other impact by leveraging use of the accept system call (bsc#1038564).
