|CVSS SCORE||7.5, (AV:N/AC:L/Au:N/C:P/I:P/A:P)|
The specific flaw exists within the parsing of a MOV file. A dref atom can contain information specifying a past location of the MOV file. A value within this atom is used to determine how many bytes to copy into a buffer without ensuring that the value is smaller than the size of the buffer, resulting in an overflow. By abusing this behavior an attacker can ensure this memory is under control and leverage the situation to achieve remote code execution under the context of the user currently logged in.
Apple has issued an update to correct this vulnerability. More details can be found at:
