Security update for Linux Kernel Live Patch 25 for SLE 12 (important)

This update for the Linux Kernel 3.12.61-52_86 fixes several issues.

The following security bugs were fixed:

• 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).
• 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).
