Ubuntu 6.06 LTS / 6.10 : gnupg2, gpgme1.0 vulnerability (USN-432-2)

Ubuntu Security Notice (C) 2007-2013 Canonical, Inc. / NASL script (C) 2007-2013 Tenable Network Security, Inc.


Synopsis :

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

Description :

USN-432-1 fixed a vulnerability in GnuPG. This update provides the
corresponding updates for GnuPG2 and the GPGME library.

Gerardo Richarte from Core Security Technologies discovered that when
gnupg is used without --status-fd, there is no way to distinguish
initial unsigned messages from a following signed message. An attacker
could inject an unsigned message, which could fool the user into
thinking the message was entirely signed by the original sender.

Solution :

Update the affected packages.

Risk factor :

Medium / CVSS Base Score : 5.0
(CVSS2#AV:N/AC:L/Au:N/C:N/I:P/A:N)
