Impact: Visiting a malicious website may lead to arbitrary code execution
Description: An implementation issue exists in QuickTime for Java, which may allow reading or writing out of the bounds of the allocated heap. By enticing a user to visit a web page containing a maliciously-crafted Java applet, an attacker can trigger the issue which may lead to arbitrary code execution. This update addresses the issue by performing additional bounds checking when creating QTPointerRef objects. Credit to Dino Dai Zovi working with TippingPoint and the Zero Day Initiative for reporting this issue.
