    Description:

    This update for the Linux Kernel 3.12.67-60_64_24 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)
