Largest Synchronized Internet Security Effort Underway to Patch Newly Found DNS Bug

A fundamental flaw in the design of the Domain Name System (DNS) was found earlier this year by security researcher Dan Kaminsky, renowned Internet Security expert. Researchers say they will fully describe the vulnerability in 30 days, after companies that operate web sites or Internet service providers can put the patches in place. The flaw is big enough that Kaminsky and other companies involved brought in government agencies such as the Department of Homeland Security and the U.S. Computer Emergency Response Team. Until the announcement today, experts had been quietly working on coordinating a massive patch affecting all types DNS implementation. Experts emphasized during the press conference today that the flaw is within the DNS protocol and in no way specific to any particular vendor.

Is this the DNS bug that was patched today by Microsoft?

Yes according to reports Ali Farshchian  –  Jul 08, 2008 2:43 PM PDT

Larry, yes according this and probably other sources which I havn't had time to look into:

One of the Microsoft fixes for Windows DNS was part of a group of patches issued today by software vendors to plug a multi-platform hole. The researcher who uncovered the vulnerability called the group patch effort the "largest synchronized security update in the history of the Internet."

Yep David A. Ulevitch  –  Jul 08, 2008 4:26 PM PDT

Larry — Yes it was.

Quite the big news yesterday! Not everyone was vulnerable, as I bet the previous commenter points out via his URL.

Here's my attempt to describe the problem to a broader audience:
