Mozilla Firefox Web Worker Array Remote Code Execution Vulnerability

This vulnerability allows remote attackers to execute arbitrary code on vulnerable installations of Mozilla Firefox. User interaction is required to exploit this vulnerability in that the target must visit a malicious page. The specific flaw exists within the implementation of web worker threads. Due to mishandling the array data type while processing posted messages, a web worker thread can be made to corrupt heap memory. An attacker can exploit this vulnerability to execute arbitrary code under the context of the user running the browser.
