Zero Day Initiative Advisory 12-077 - 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 visit a malicious page or open a malicious file. The specific flaw exists within the QuickTimeVR.qtx component. A signedness error exists when processing a QTVRStringAtom having an overly large "stringLength" parameter. This can be exploited to cause a stack-based buffer overflow and execute arbitrary code under the context of the user running the application.
