This vulnerability allows remote attackers to execute arbitrary code on vulnerable installations of Apple’s QuickTime player. User interaction is required to exploit this vulnerability in that the target must visit a malicious page. The specific flaw exists within how the application handles a malformed atom type when playing a movie encoded with uncompressed audio. When decoding the audio sample the application will use a 16-bit length for allocating a buffer, and a different one for initializing it. This can cause memory corruption which can lead to code execution under the context of the application.
