As you may know (or not) there is a vulnerability found in OpenSSL. This Open Source library is used all over the place like Apache web servers, SSH, VPN, etc. so this is a big one.
You can read more about it at http://heartbleed.com .
Also PostgreSQL uses OpenSSL for it’s SSL connections.
PostgreSQL core member Magnus Hagander did a brief writeup about this vulnerability and how it affects PostgreSQL.

And as Magnus already mentioned in his blog, don’t forget to restart your services after updating as the OpenSSL update doesn’t do that for you.
