Popular Web browser
has been updated fixing a security issue found in the application. Specifically, the update addresses the
FTP PASV port-scanning
issue, which allowed a malicious web page hosted on a specially-coded FTP server 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, said Mozilla. Firefox 18.104.22.168 is available for download from the developer’s Web site.
