Mozilla Firefox 18.104.22.168 Released with Fix for firefoxurl:// Exploit
Wednesday July 18th, 2007
Mozilla Firefox 22.214.171.124 has been released and is currently being distributed to Firefox 2 users via the application's built-in software update system. The browser upgrade fixes several security bugs, which are detailed in the Firefox 126.96.36.199 section of the Mozilla Foundation Security Advisories page.
Firefox 188.8.131.52 includes a fix for the firefoxurl:// security exploit, which allows an attacker to use Microsoft Internet Explorer to trick Firefox into executing malicious code. Whether Firefox or IE is responsible for the flaw has been a matter of debate over the past week. The Mozilla Foundation security advisory about the firefoxurl:// issue maintains that it's a problem in IE and notes that other applications could be exploited in the same way. Others have argued that it's Firefox's responsibility to vet incoming data (something 184.108.40.206 now does).
Firefox 220.127.116.11 can be downloaded from the Firefox product page. The Firefox 18.104.22.168 Release Notes contain more general information about the upgrade. A similar update for Mozilla Thunderbird is expected shortly.
#7 Useless to blame anyone

As I stated in the other topic, I launched the proof of concept from SeaMonkey, a fellow Gecko application, not Internet Explorer. I don't see why IE should be blamed when it's not the only one that is vulnerable of executing the exploit. In any case, it's just good that it's fixed now. I don't really care who is at fault, just that there's an official fix for the problem.
