SUSE SLES12 Security Update : kernel (SUSE-SU-2017:1300-1)

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


Synopsis :

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

Description :

This update for the Linux Kernel 3.12.60-52_54 fixes several issues.
The following security bugs were fixed :

- CVE-2017-7308: The packet_set_ring function in
net/packet/af_packet.c in the Linux kernel did not
properly validate certain block-size data, which allowed
local users to cause a denial of service (overflow) or
possibly have unspecified other impact via crafted
system calls (bsc#1030575, bsc#1031660).

- bsc#1030467: Updated Dirty COW fix. The former patch
caused some apps to freeze in rare circumstances

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.
