OpenSSL Heartbleed Vuln [SEVERE]

Update yo OpenSSL, because I can grab all ur private keys.

http://heartbleed.com
I was just reading this -As reported all over the web by now, there was a critical flaw in OpenSSL. This flaw affects all of us, as it hits the authentication methods of about 2/3 of the webservers out there. The vulnerability has been dubbed "heartbleed" bug. The name refers tothe heartbeat extension by which it is caused. The heartbeat extension usually serves to keep a connection alive, but due to the bug it now allows others to recover data sent over SSL/TLS. This compromises the keys used to identify you to the server and allows to read the encrypted traffic you sent: name and passwords, most notably.

Cryptic's VPN is vulnerable, sucks for me.

I'm feeling stupid right now, but normal people don't have OpenSSL downloaded and it is the websites job to update?
