Apple QuickTime includes the ability to integrate QuickTime into Java applications and applets. This feature is known as QuickTime for Java. Apple QuickTime for Java fails to properly restrict the instantiation and manipulation of Java objects. This can allow an attacker to create a specially crafted Java applet that can bypass Java applet security restrictions. Once the security restrictions are bypassed, the malicious applet may be able to access and manipulate system resources.

More information is available in About Security Update (QuickTime 7.1.6).

By convincing a user to run a malicious Java 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.

Apply an update
Apply an update, as specified in the Apple QuickTime 7.1.6 security update.

On Microsoft Windows the QuickTime built-in auto-update mechanism may not detect this update. Instead, Windows users should check for updates using Apple Software Update or download and install the update manually.

Disable Java

This vulnerability can be mitigated by disabling Java in your web browser. Instructions for disabling Java can be found in the "Securing Your Web Browser" document.
