Apple QuickTime movie buffer overflow vulnerability

Vulnerability Note VU#683700

Original Release Date: 2006-09-13 | Last Revised: 2006-09-13


A buffer overflow vulnerability in the way Apple QuickTime handles movie files could allow a remote attacker to execute arbitrary code or cause a denial-of-service condition.


A buffer overflow vulnerability in QuickTime for Windows and Mac OS X 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, an attacker can trigger the overflow.

Depending on settings, a web browser could automatically open a QuickTime movie. Apple iTunes includes QuickTime.


A remote, unauthenticated attacker can execute arbitrary code or create a denial-of-service condition.


Apple has addressed this issue in Quicktime 7.1.3. The latest version of QuickTime is availble from the QuickTime download site.
