Ø I get the heartbeating message on both unpatched and patched servers. Should that make me worry about the patched machines? Not necessarily. If they updated to the 'g' release, then they are doing buffer-overrun checking and you're safe. You can probably find out by connecting to your server (via s_client again) and seeing what it says in the server line, as in echo HEAD / HTTP/1.0 | openssl s_client -connect $HOST:$PORT The server usually says things like "apache/2.0 openssl/1.0.1g ..." and other modules that are bundled in.
To be safest, heartbeats should just be disabled. Nobody really uses them. /r$ -- Principal Security Engineer Akamai Technology Cambridge, MA
