This vulnerability allows remote attackers to execute arbitrary code on vulnerable installations of Apple QuickTime. User interaction is required to exploit this vulnerability in that the target must open a malicious file.

The specific flaw exists in the parsing of the QuickTime VR 'obji' atom. When the size of the atom is set to 0, a stack overflow condition occurs resulting in the execution of arbitrary code.
