This is one of the caveats of running open source software. If they can identify what version you're running, you are at risk. All they have to do is run through the list of bug fixes since that version and you have your ammo. Hell most likely people already wrote scripts for certain vulnerabilities so all you need to do is pull the script off the shelf and point it in the direction desired.
While MS has its fair share of security issues, not all of them are publicaly disclosed.
