The specific flaw exists within the way Quicktime handles H.264 streams. When parsing the Sequence Parameter Set data for a H.264 stream it reads the frame cropping offset fields. When those fields contain incorrect data Quicktime will eventually write outside the buffer allocated for the movie stream. This can result in remote code execution under the context of the current user.
Apple has issued an update to correct this vulnerability. More details can be found at:
