I've received a warning from the authority that generated my certificate, it says that there is bug in OpenSSL and it has been found affecting versions 1.0.1.
As I understand, I have to upgrade to 1.0.1h to fix this bug.
This is the first time I deal with these stuff and I'm worried about how it will affect my server.
Do I have to restart any services? And what exactly? I have to make sure this is not going to take too long.
