Apple QuickTime VR Track Header Atom Heap Corruption Vulnerability

This vulnerability allows 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 within the parsing of ‘tkhd’ atoms found inside QuickTimeVR files. Improper validation of the transform matrix data results in a heap chunk header overwrite leading to arbitrary code execution under the context of the currently logged in user.
