As much as I would love to take pot shots at Apple, this is actually a serious problem. ErrataSec is currently testing to see how this affects Windows and OSX (because it’s a quicktime bug, it runs on both OSes). Since there has been a lot of interest in bugs like this for hacking through social networking sites you can expect this bug to get some serious play.
The month of Mac bugs has started with a bang!
Brian Krebs is covering this as well.
