ACDC - if you use https (SSL certificate) and you used OpenSSL to generate keys for your SSL certificate then you should check your server, as you may be vulnerable to Heartbleed, it will depend on the version of OpenSSL that was used.
Detection and updating to a new version is quick and relatively painless. You can also test for Heartbleed vulnerability here: https://www.ssllabs.com/ssltest/
While it has nothing to do with the Aware software, if you are running a SSL Certificate (which really every Aware production install should do) then it will affect your Aware installation and your Aware users.
