A 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 the quickTime.qts while parsing corrupted .pict files. The module contains a vulnerable memory copy loop which searches for a terminator value. When this value is changed or omitted, a heap corruption occurs allowing the execution of arbitrary code. Version 7.4.1 is affected.
