Ubuntu Security Notice (C) 2016 Canonical, Inc. / NASL script (C) 2016 Tenable Network Security, Inc.


Synopsis :

The remote Ubuntu host is missing one or more security-related
patches.

Description :

USN-3083-1 fixed vulnerabilities in the Linux kernel for Ubuntu 14.04
LTS. This update provides the corresponding updates for the Linux
Hardware Enablement (HWE) kernel from Ubuntu 14.04 LTS for Ubuntu
12.04 LTS.

Dmitry Vyukov discovered that the IPv6 implementation in the Linux
kernel did not properly handle options data, including a
use-after-free. A local attacker could use this to cause a denial of
service (system crash) or possibly execute arbitrary code.
(CVE-2016-3841)

It was discovered that a race condition existed when handling
heartbeat- timeout events in the SCTP implementation of the Linux
kernel. A remote attacker could use this to cause a denial of service.
(CVE-2015-8767).

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

Solution :

Update the affected linux-image-3.13-generic and / or
linux-image-3.13-generic-lpae packages.
