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 QuickTimeAuthoring.qtx during the parsing of DELTA_FLI chunks stored within a malformed .fli file.
