Security flaws found in fix for Firefox, SeaMonkey

Mozilla issues security updates
December 20, 2006
Mozilla on Monday released security updates for Firefox 2 and Firefox 1.5. Security updates for Firefox 1.5 will be available only until April 24, 2007, when Mozilla will stop supporting the earlier version. Mozilla is encouraging current 1.5 users to upgrade to 2.0 soon. Current users of Firefox 2.0 and 1.5 will receive an automatic update notification and will need to reload the browser for the changes to take effect. Changes in this update patch a flaw in the FTP protocol used by Firefox.
It has been reported that a specially-coded FTP server could use this vulnerability to perform a rudimentary port-scan of machines inside the firewall. Mozilla says the vulnerability by itself poses no danger, but information about an internal network may be revealed and become useful to an attacker should there be other vulnerabilities present on the network. This update was first tested in beta release by Mozilla a few days ago.

Terrible update Mozilla.
If the problem is restricted to FF: Save your bookmarks to another folder, then do a complete uninstall of Firefox, delete your FF profile from Documents and Settings, then reinstall. If you use FF password manager, refer to FF documentation as to how to save and restore this as well. If you use Add-ons, you will need to reinstall them, as well as add-ins like Flash. Yeah, it will take you about half an hour, but it usually fixes sluggishness.
