Apple QuickTime genl Atom Remote Code Execution Vulnerability
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 open a malicious file.
The specific flaw exists in QuickTimeMPEG.qtx and results when QuickTime attempts to parse a malformed 'genl' atom that may be present in any QuickTime media file. A heap overflow is caused when QuickTime fails to perform proper bounds checking on the amount of data copied to the heap by a set of nested loops which can result in arbitrary code execution.
