Hotmail, Yahoo! guard against virus-spreading flaw
Hotmail and Yahoo! have patched their web-based email services to guard against becoming vectors for the spread of mass-mailing viruses.
As reported last week, a security researcher discovered that cross-site scripting vulnerabilities make it possible to replicate Melissa-type worms through Web mail services.
Other Web-based email services are advised to follow Hotmail's lead in acting to prevent virus writers exploiting their systems to spread worms, or other forms of malicious code. ®
