Description:

   This update for the Linux Kernel 3.12.61-52_83 fixes several issues.

   The following security bugs were fixed:

   - CVE-2017-1000112: Prevent a race condition in net-packet code that could
     have been exploited by unprivileged users to gain root access
     (bsc#1052368).
   - CVE-2017-7645: The NFSv2/NFSv3 server in the nfsd subsystem in the Linux
     kernel allowed remote attackers to cause a denial of service (system
     crash) via a long RPC reply (bsc#1046191).
   - CVE-2017-9242: The __ip6_append_data function in net/ipv6/ip6_output.c
     in the Linux kernel was 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).
