Microsoft Edge Chakra JIT BailOutOnInvalidatedArrayHeadSegment Check Bypass

This strike exploits a vulnerability in the Microsoft Edge browser. Specifically, the vulnerability exists in the Javascript Chakra engine. It is possible to bypass the check whether a given object is an array by wrapping an object with the CrossSite class to replace the vtable of the object. This may lead to a denial of service condition in the browser, or potentially remote code execution.
