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.
