The specific flaw exists within how the application calculates the padding for an MPEG sample. When calculating the padding, the MPEG library will subtract this from another length without checking for underflow. This resulting length will then be used in a memcpy operation into a statically sized buffer allocated on the heap. This can lead to code execution under the context of the application.
Apple has issued an update to correct this vulnerability. More details can be found at:
