Security update for Linux Kernel Live Patch 19 for SLE 12 (important)

This update for the Linux Kernel 3.12.61-52_66 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-2017-7645: 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, related to net/sunrpc/svc.c,
  fs/nfsd/nfs3xdr.c, and fs/nfsd/nfsxdr.c (bsc#1046191).
• CVE-2017-2636: Race condition in drivers/tty/n_hdlc.c in the Linux
  kernel allowed local users to gain privileges or cause a denial of
  service (double free) by setting the HDLC line discipline (bsc#1027575).
• A SUSE Linux Enterprise specific regression in tearing down network
  namespaces was fixed (bsc#1044878)
• 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).
