Ubuntu Security Notice (C) 2013-2016 Canonical, Inc. / NASL script (C) 2013-2016 Tenable Network Security, Inc.


Synopsis :

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

Description :

Daniel Kahn Gillmor discovered that GnuPG treated keys with empty
usage flags as being valid for all usages. (CVE-2013-4351)

Taylor R Campbell discovered that GnuPG incorrectly handled certain
OpenPGP messages. If a user or automated system were tricked into
processing a specially crafted message, GnuPG could consume resources,
resulting in a denial of service. (CVE-2013-4402).

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 gnupg and / or gnupg2 packages.
