   An update that fixes three vulnerabilities is now available.

Description:

   This update for the Linux Kernel 3.12.74-60_64_45 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).
