Apple has released a patch for the QuickTime vulnerability now famously exploited by Dino Dai Zovi (off site) at CanSecWest. Apple also “warned QuickTime Pro users who download the new version that the software will disable the QuickTime Pro functionality in earlier versions, including QuickTime 5 or QuickTime 6. Users who continue with the installation will have to purchase a new QuickTime 7 Pro key to regain QuickTime Pro functionality.”
This patch affects Windows and Mac users. And Apple still sucks.
