Ubuntu 5.04 / 5.10 / 6.06 LTS : gnupg vulnerability (USN-332-1)

Ubuntu Security Notice (C) 2006-2016 Canonical, Inc. / NASL script (C) 2007-2016 Tenable Network Security, Inc.


Synopsis :

The remote Ubuntu host is missing a security-related patch.

Description :

Evgeny Legerov discovered that gnupg did not sufficiently check the
validity of the comment and a control field. Specially crafted GPG
data could cause a buffer overflow. This could be exploited to execute
arbitrary code with the user's privileges if an attacker can trick an
user into processing a malicious encrypted/signed document with gnupg.

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 package.

Risk factor :

Medium / CVSS Base Score : 5.0
(CVSS2#AV:N/AC:L/Au:N/C:N/I:N/A:P)
CVSS Temporal Score : 3.9
(CVSS2#E:POC/RL:OF/RC:C)
Public Exploit Available : true
