Ubuntu 7.04 / 7.10 / 8.04 LTS : openvpn regression (USN-612-10)

Ubuntu Security Notice (C) 2008-2016 Canonical, Inc. / NASL script (C) 2008-2016 Tenable Network Security, Inc.


Synopsis :

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

Description :

USN-612-3 addressed a weakness in OpenSSL certificate and key
generation in OpenVPN by adding checks for vulnerable certificates and
keys to OpenVPN. A regression was introduced in OpenVPN when using TLS
with password protected certificates which caused OpenVPN to not start
when used with applications such as NetworkManager.

A weakness has been discovered in the random number generator used by
OpenSSL on Debian and Ubuntu systems. As a result of this weakness,
certain encryption keys are much more common than they should be, such
that an attacker could guess the key through a brute-force attack
given minimal knowledge of the system. This particularly affects the
use of encryption keys in OpenSSH, OpenVPN and SSL certificates.

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 openvpn package.

Risk factor :

High
