Apple QuickTime contains a heap buffer overflow vulnerability. This vulnerability may allow an attacker to execute arbitrary code with the privileges of the user running QuickTime. By convincing a user to open a specially crafted QuickTime movie file, an attacker can trigger the overflow.

Apple iTunes includes the QuickTime player.

Note that this vulnerability may be present in QuickTime versions prior to 7.1.5 running on Mac OS X and Microsoft Windows 2000, XP and Vista.

A remote, unauthenticated attacker can execute arbitrary code or create a denial-of-service condition. The crafted QuickTime movie file may be supplied on a web page, in an email for the victim to select, or by some other means designed to encourage them to invoke QuickTime on the exploit file.

Apple has released QuickTime 7.1.5 to address this issue.
