From CNET:

On July 8, IOActive researcher Dan Kaminsky disclosed a flaw in the DNS but would not provide the details until all the affected vendors had released patches and all the systems worldwide could be patched. He figured that it would take about 30 days for that to happen.

The 30-day mark just happened to coincide with his speaking engagement at Black Hat in Las Vegas on August 6.

But on Monday, fellow Black Hat presenter Halvar Flake attacked Kaminsky’s plea that a security flaw such as this be kept a secret. Flake then proceeded to lay out what he thought the flaw was. Turns out, he was right and laid the foundation for others to create and publicize an exploit.

Other than what was linked in that article another exploit has also been added to the Packet storm exploit archive. Both of these are Metasploit modules and HD Moore (founder of the Metasploit project) is listed as one of the exploits authors.

Cheers and happy patching!
