Hey, hey, hey. Our favorite browser just released an update with Firefox 2.0.0.3 it fixes a few security issues and website compatibilities.

The security update fixes the MFSA 2007-11 FTP PASV port-scanning vulnerability. Here are some details about this:

mark@bindshell.net reported that a malicious web page hosted on a specially-coded FTP server could use this feature to perform a rudimentary port-scan of machines inside the firewall of the victim. By itself this causes no harm, but information about an internal network may be useful to an attacker should there be other vulnerabilities present on the network.
