   An update that fixes one vulnerability is now available.

Description:

   This update for the Linux Kernel 4.4.120-94_17 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 can 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).
