Vulnerability Details


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.
