An update that solves one vulnerability and has one errata
is now available.

Description:

This update for the Linux Kernel 3.12.61-52_111 fixes one issue.

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. This fixes the earlier kgraft update, that could have
caused crashes when trying to exploit this vulnerability after applying
the kgraft update (bsc#1064392, bsc#1064388).


Patch Instructions:

To install this SUSE Security Update use YaST online_update.
