|References:||#1063671 #1064392 #1066471 #1066472|
An update that solves two vulnerabilities and has two fixes is now available.
This update for the Linux Kernel 4.4.21-90 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
- 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)
