Mozilla Firefox 22.214.171.124 Released with Fix for firefoxurl:// Exploit
Wednesday July 18th, 2007
Mozilla Firefox 126.96.36.199 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 188.8.131.52 section of the Mozilla Foundation Security Advisories page.
Firefox 184.108.40.206 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 220.127.116.11 now does).
Firefox 18.104.22.168 can be downloaded from the Firefox product page. The Firefox 22.214.171.124 Release Notes contain more general information about the upgrade. A similar update for Mozilla Thunderbird is expected shortly.
I agree with HwC in what he said above. The fact that Mozilla fixed this First and Foremost kind of leaves M$ sitting there now with egg on their faces showing the world just how much, and how serious they are, about their client's/user's security.
BRAVO Mozilla! Two thumbs up for yet another job well done!
