Yeah, good thinking pointing that out.  HUGE warning to everyone.   
This isn't just something you can run an update and ignore.  The KEYS  
themselves are vulnerable, so every SSH host key, client key, openVPN  
key or openssl cert created with one of these systems should be  
considered vulnerable.  If you made a key on a vulnerable machine and  
put it on an unaffected machine they key is still bad.
