|CVSS SCORE||7.5, (AV:N/AC:L/Au:N/C:P/I:P/A:P)|
The specific flaw exists within the QuicktimeH264 modules in the QuickTime player that handles H264 encoded movies. When the value for 'pic_width_in_mbs_minus_1' and 'pic_height_in_map_units_minus_1' in the AVCC header data differs from the actual picture width and height a heap buffer overflow occurs. This can result in remote code execution under the context of the current process.
Apple has issued an update to correct this vulnerability. More details can be found at:
