Description

This strike exploits a vulnerability in Spidermonkey, the Javascript engine of Mozilla Firefox. An attacker can craft Javascript promise resolutions in such a way that make it possible to cause an out-of-bounds read off the end of an array resized during script execution. This can lead to a denial of service or potentially allow for remote code execution to occur.
