   An update that fixes one vulnerability is now available.

Description:

   This update for the Linux Kernel 4.12.14-25_6 fixes one issue.

   The following security issue was fixed:

   - CVE-2018-10938: It was found that a crafted network packet sent remotely
     by an attacker may force the kernel to enter an infinite loop in the
     cipso_v4_optptr() function in net/ipv4/cipso_ipv4.c leading to a
     denial-of-service. A certain non-default configuration of LSM (Linux
     Security Module) and NetLabel should be set up on a system an attacker
     could leverage this flaw (bsc#1106191).
