   An update that fixes two vulnerabilities is now available.

Description:

   This update for the Linux Kernel 4.12.14-25_3 fixes several issues.

   The following security issues were 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.
   - CVE-2018-10902: It was found that the raw midi kernel driver did not
     protect against concurrent access which lead to a double realloc (double
     free) in snd_rawmidi_input_params() and snd_rawmidi_output_status(),
     allowing a malicious local attacker to use this for privilege escalation
     (bsc#1105323).
