Mozilla Releases Firefox Update To Patch Port-Scanning Flaw

Mozilla released an update to its Firefox browser late on Tuesday to patch a port-scanning vulnerability.
The FTP PASV port-scanning flaw, which is rated a low risk, could enable a hacker to take a look around inside a victim's machine. An advisory on the Mozilla site warns that a malicious Web page hosted on a specially-coded FTP server could use the scanning feature to perform a rudimentary port-scan of machines inside a user's firewall.
"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," Mozilla stated in the advisory.
The update -- Firefox 2.0.0.3 -- also deals with several Web compatibility regressions introduced with Firefox 2.0.0.2. An update to address the same regressions for the Firefox 1.5 Branch, Firefox 1.5.0.11, also has been released.
Mozilla pushed out a beta release of Firefox 2.0.0.3 between last Friday and Saturday. Mozilla is beginning to treat its security and stability updates like it does its major version releases, issuing beta releases to its tester community.
