Just wanted to share that there is a serious problem with openssl that allows public users to get past SSL security. This affected most recent Linux OS distributions.
It lets people steal your private keys and do other bad things. Pretty serious problem.
Not too hard to fix. I had to upgrade ours, and restart the services to fix the vulnerability. It doesn't auto-fix when you update openssl only, the nginx/apache restart was required on both ubuntu and centos for me. Nginx also required libssl to be upgraded for me, not just openssl.
You can check for server vulnerability more quickly here:
I'm on ubuntu 13.04 still, so I had to manually upgrade to saucy packages to fix it since it's no longer supported.
