Ubuntu Security Notice (C) 2008-2013 Canonical, Inc. / NASL script (C) 2008-2013 Tenable Network Security, Inc.
The remote Ubuntu host is missing a security-related patch.
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.
Update the affected openvpn package.
