Description

This strike exploits a vulnerability in Microsoft Edge. Specifically, the vulnerability exists in the Javascript Chakra engine. It is possible to craft Javascript in such a way that an object is passed to the InstanceOf method to dereference a pointer value of an assumed type, which can be changed causing type confusion to occur. This may lead to a denial of service condition in the browser, or potentially remote code execution.
