Think that you won't need to install the new iTunes update because you don't have a new iPod, or because you run Windows Vitsa?

Wrongo, buddy.

Apple has slipped a new security fix into the latest version of iTunes that makes the update important for everyone.

The vulnerability lies within the way iTunes handles cover art. If an attacker were to create and launch a specially malformed music file, a crash would be triggered that could potentially allow for a malware installation.

Seeing as how iTunes will ask to install the update when you launch, it shouldn't be too hard to remember to install this update.
