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

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

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 :

High / CVSS Base Score : 7.8
(CVSS2#AV:N/AC:L/Au:N/C:N/I:C/A:N)
CVSS Temporal Score : 6.8
(CVSS2#E:ND/RL:OF/RC:C)
Public Exploit Available : true
