Ubuntu 5.10 / 6.06 LTS / 6.10 : gnupg vulnerability (USN-432-1)

Ubuntu Security Notice (C) 2007-2015 Canonical, Inc. / NASL script (C) 2007-2015 Tenable Network Security, Inc.

Synopsis :

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

Description :

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 gnupg package.

Risk factor :

High / CVSS Base Score : 7.8
CVSS Temporal Score : 6.8
Public Exploit Available : true
