Seriously now, OS X is starting to act a bit too much like Windows. But hey, if it makes things better, why the heck not?

If it isn’t on your desktop yet, run Software Update to get Quicktime 7.4.1 (54.1mb), which “addresses security issues and improves compatibility with third-party applications.”

A quick dig into the guts of Apple Support shows us the real reason for the revision:

Available for: Mac OS X v10.3.9, Mac OS X v10.4.9 or later, Mac OS X v10.5 or later, Windows Vista, XP SP2

Impact: Visiting a malicious website may lead to an unexpected application termination or arbitrary code execution

Description: A heap buffer overflow exists in QuickTime’s handling of HTTP responses when RTSP tunneling is enabled. By enticing a user to visit a maliciously crafted webpage, an attacker may cause an unexpected application termination or arbitrary code execution. This update addresses the issue through improved bounds checking.”

Not that I understand any of it, but it sounds good.

No word yet if it tanks anything, but go get, if you’re the Early Updater type like me.
