Ubuntu 10.04 LTS / 12.04 LTS / 13.10 / 14.04 LTS : gnupg, gnupg2 vulnerability (USN-2258-1)

Ubuntu Security Notice (C) 2014-2016 Canonical, Inc. / NASL script (C) 2014-2016 Tenable Network Security, Inc.


Synopsis :

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

Description :

Jean-Rene Reinhard, Olivier Levillain and Florian Maury 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.

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.

Risk factor :

Medium / CVSS Base Score : 5.0
(CVSS2#AV:N/AC:L/Au:N/C:N/I:N/A:P)
CVSS Temporal Score : 4.3
(CVSS2#E:ND/RL:OF/RC:C)
