Ubuntu Security Notice (C) 2009-2016 Canonical, Inc. / NASL script (C) 2009-2016 Tenable Network Security, Inc.


Synopsis :

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

Description :

Multiple flaws were discovered in the Kerberos GSS-API and ASN.1
routines that did not correctly handle certain requests. An
unauthenticated remote attacker could send specially crafted traffic
to crash services using the Kerberos library, leading to a denial of
service.

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 packages.
