SUSE SLED12 / SLES12 Security Update : kernel (SUSE-SU-2016:2592-1) (Dirty COW)

This script is Copyright (C) 2016-2017 Tenable Network Security, Inc.


Synopsis :

The remote SUSE host is missing one or more security updates.

Description :

The SUSE Linux Enterprise 12 SP1 kernel was updated to fix two issues.
This security bug was fixed :

- CVE-2016-5195: Local privilege escalation using
MAP_PRIVATE. It is reportedly exploited in the wild
(bsc#1004418). This non-security bug was fixed :

- sched/core: Fix a race between try_to_wake_up() and a
woken up task (bsc#1002165, bsc#1001419).

Note that Tenable Network Security has extracted the preceding
description block directly from the SUSE security advisory. Tenable
has attempted to automatically clean and format it as much as possible
without introducing additional issues.
