OpenSSL vulnerability on Debian-based systems CVE-2008-0166

OpenSSL 0.9.8c-1 up to 0.9.8g-9 on Debian-based operating systems uses a 
random number generator that generates predictable numbers, which makes 
it easier for remote attackers to conduct brute force guessing attacks 
against cryptographic keys.   This vulnerability only affects 
Debian-based distributions and does not affect any Red Hat distributions.

How this affects OpenVPN:

Any keys which were generated on the vulnerable distributions (Debian, 
Ubuntu, Kubuntu) using openvpn --genkey or the easy-rsa scripts should 
be considered compromised, since the security of each of these 
operations would depend on the quality of the randomness provided by the 
underlying OpenSSL library.  You would want to revoke these keys, and 
rebuild them after having applied the fix.
