An update that fixes one vulnerability is now available.

Description:

This update for the Linux Kernel 3.12.61-52_128 fixes one issue.

The following security issue was fixed:

- CVE-2018-16884: A flaw was found in the Linux kernel's NFS41+
subsystem.
NFS41+ shares mounted in different network namespaces at the same time
could make bc_svc_process() use wrong back-channel IDs and cause a
use-after-free vulnerability. Thus a malicious container user could
cause a host kernel memory corruption and a system panic. Due to the
nature of the flaw, privilege escalation cannot be fully ruled out
(bsc#1119947).
