LinuxSecurity.com: USN-612-3 addressed a weakness in OpenSSL certificate and key generation in OpenVPN by introducing openssl-blacklist to aid in detecting vulnerable private keys. This update enhances the openssl-vulnkey tool to check X.509 certificates as well, and provides the corresponding update for Ubuntu 6.06. While the OpenSSL in Ubuntu 6.06 was not vulnerable, openssl-blacklist is now provided for Ubuntu 6.06 for checking certificates and keys that may have been imported on these systems.
