This vulnerability allows 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 parsing of QuickTime files that utilize the Indeo video codec. A lack of proper bounds checking within QuickTimeInternetExtras.qtx can result in a stack based buffer overflow leading to arbitrary code execution under the context of the currently logged in user.
