The specific flaw exists within the way QuickTime handles the LongComment PICT opcode. It converts an unsigned 16 bit value into a signed 32 bit value after it performs some mathematical operations on it. This value is later used as a size parameter for a memory copy function that copies from the file onto the heap. An attacker can leverage the situation to achieve remote code execution under the context of the user currently logged in.
