USN-612-2 introduced protections for OpenSSH, related to the OpenSSL
vulnerabilities addressed by USN-612-1. This update provides the
corresponding updates for OpenSSH in Ubuntu 6.06 LTS. While the OpenSSL
in Ubuntu 6.06 is not vulnerable, this update will block weak keys

particularly affects the use of encryption keys in OpenSSH, OpenVPN
and SSL certificates.
The problem can be corrected by upgrading your system to the
following package versions:
Ubuntu 6.06 LTS:
In general, a standard system upgrade is sufficient to effect the
