Apple QuickTime for Java QTPointerRef heap memory corruption vulnerability

Original Release date: 02 May 2007 | Last revised: 02 May 2007


Apple QuickTime for Java contains a heap memory corruption vulnerability, which may allow a remote, unauthenticated attacker to execute arbitrary code on a vulnerable system.


Apple QuickTime includes the ability to integrate QuickTime into Java applications and applets. This feature is known as QuickTime for Java. QuickTime for Java fails to properly validate parameters when QTPointerRef objects are created, which can lead to heap memory corruption.


By convincing a user to run a malicious Java application or applet, a remote, unauthenticated attacker may be able to execute arbitrary code with the privileges of the user. This can be accomplished by visiting a malicious web page with a Java-enabled web browser.
