|CVSS SCORE||9, (AV:N/AC:L/Au:N/C:P/I:P/A:C)|
This vulnerability allows remote attackers to execute arbitrary code on vulnerable installations of Apple QuickTime Player. User interaction is required to exploit this vulnerability in that the target must visit a malicious page or open a malicious file.
The specific flaw exists during the parsing of samples from a malformed MOV file utilizing the H.264 codec. While parsing data to render the stream, the application will miscalculate a length that is used to initialize a heap chunk that was allocated in a header. If the length is larger than the size of the chunk allocated, then a memory corruption will occur which can lead to code execution under the context of the application.
Fixed in QuickTime 7.6.6
