An update that fixes one vulnerability is now available.

Description:

This update for the Linux Kernel 3.12.61-52_119 fixes several issues.

The following security issue was fixed:

- CVE-2017-15649: net/packet/af_packet.c in the Linux kernel allowed local
users to gain privileges via crafted system calls that trigger
mishandling of packet_fanout data structures, because of a race
condition (involving fanout_add and packet_do_bind) that leads to a
use-after-free, a different vulnerability than CVE-2017-6346
(bsc#1064392)
