Description

This vulnerability allows remote attackers to execute arbitrary code on vulnerable installations of the Oracle Java. User interaction is required to exploit this vulnerability in that the target must visit a malicious page or run a malicious file.

The specific bypass exists within usage of MethodHandles invoking AccessController.doPrivilegedWithCombiner. This allows a malicious applet to execute attacker supplied code resulting in remote code execution under the context of the process.
