Apple Java CColourUIResource Pointer Dereference Code Execution Vulnerability

his vulnerability allows remote attackers to execute arbitrary code on vulnerable installations of Apple Java HotSpot. User interaction is required to exploit this vulnerability in that the target must visit a malicious page. The specific flaw exists in the undocumented apple.laf.CColourUIResource(long, int, int ,int, int) constructor. When passing a long integer value as the first argument, the value is interpreted as pointer to an Objective-C object. By constructing a special memory structure and passing the pointer to the first argument an attacker may execute arbitrary code.
