Description

This strike exploits a vulnerability in Microsoft Edge. Specifically, the Javascript Chakra engine assumes that the specified array will be a float array, however, it is possible to modify this type with the valueOf handler, which will result in type confusion. This can cause a denial of service in the browser or potentially allow for remote code execution to occur.
