which one of these updates is essential to secure my server from the OpenSSL vulnerability. i dont want to screw with anything else. can i install these individually via the "update server" panel i installed on my server? Which ones are essential?  Why arent they in one file??? whats the easiest way to install all of them? what would the rsync commands be, in newbie terms, i have Never done this, and just started using linux, i would just leave it but i dont want my server open to attack.  
Thank you for any advise!
