Everyone blew this supposed "Mac" security issue out of the water, it seems. The Mac was "hacked," but it wasn't exactly specific to the Mac as the issue could be replicated in any browser on any system. It was a local exploit, at best, and it involved cross-site scripting, something that is inherently dangerous on all computers.
Please let me know when the Mac can be remotely rooted, though. That will be some serious news.
