Looks like the exploit code has been released by HD Moore as a Metasploit module. Hope everyone took the DNS patching requests seriously since we all know Metasploit is really easy to use (yes, especially for script kiddies!).
If you haven’t patched your DNS yet…do it now! Check here for more information and here to check your DNS servers to see if they are vulnerable. If your ISP’s DNS is still vulnerable…change your DNS servers to use OpenDNS!
