Our own Dave Caolo suggested FaceTime's widely publicized security flaw would be easily fixed, and it turns out he was right. Initially, FaceTime allowed users with physical access to a machine to edit a user's information without first having to enter a password. According to Cocoa Touch Apps, Apple's already patched this hole with a server-side workaround. I verified this myself: instead of giving anyone and everyone in front of your Mac access to your Apple-related info, clicking "View Account" in FaceTime now does... precisely nothing. It just kicks you back to the account preferences tab.
It's a somewhat silly workaround, and it's likely a temporary one until Apple releases a FaceTime update. Meanwhile, it's good to see that Apple took this problem seriously enough to issue a quick fix for its still-in-beta software.
