Mozilla Firefox Spidermonkey IonMonkey ObjectGroup Type Confusion

This strike exploits a vulnerability in Mozilla Firefox. Specifically, the vulnerability exists in the Javascript engine Spidermonkey. It is possible to craft Javascript in such a way that in IonMonkey an unexpected ObjectGroup in an ObjectGroupDispatch operation might allow for unsafe code to execute. This could cause type confusion to occur causing a denial of service condition in the browser or potentially allowing for remote code execution to occur.
