|CVSS SCORE||7.5, (AV:N/AC:L/Au:N/C:P/I:P/A:P)|
The specific flaw exists within how the application parses a specific opcode within a PCT file. When resizing a heap buffer, the application will use a signed word read from the file to calculate the resulting size. This can be used to force the target buffer to be of an undersized length. Usage of this buffer will result in a buffer overflow in the context of the application.
Apple has issued an update to correct this vulnerability. More details can be found at:
