       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).
