Mozilla Foundation released Firefox 18.104.22.168 to patch a whopping 10 security holes, at least four of which are extremely dangerous.
One problem could allow scripts to escape the browser's sandbox environment and run with elevated privileges. A related problem could allow an attacker to inject a script from one site into another.
Another problem could allow an attacker to access someone's navigation history and crash the browser. And yet another problem leads to memory corruption, which could potentially be exploited to execute arbitrary code.
Firefox 22.214.171.124 is now available for Windows, Linux, and OS X.
