   An update that solves two vulnerabilities and has two fixes
   is now available.

Description:

   This update for the Linux Kernel 3.12.74-60_64_48 fixes several issues.

   The following security issues were 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)
   - CVE-2017-13080: Wi-Fi Protected Access (WPA and WPA2) allowed
     reinstallation of the Group Temporal Key (GTK) during the group key
     handshake, allowing an attacker within radio range to replay frames from
     access points to clients (bsc#1063671, bsc#1066472, bsc#1066471)
