The Microsoft Windows DNS server contains a response validation vulnerability. If successfully exploited, this vulnerability may allow an attacker to poison the affected DNS server's cache.
The Domain Name System (DNS) is responsible for translating host names to IP addresses (and vice versa) and is critical for the normal operation of internet-connected systems.
Per Microsoft Security Bulletin MS09-008:
An attacker may be able to insert arbitrary values in the DNS cache. An attacker with the ability to conduct a successful attack can cause a nameserver's clients to contact the incorrect, and possibly malicious, hosts for particular services. Consequently, web traffic, email, and other important network data can be redirected to systems under the attacker's control.
Microsoft has released an update to address this issue. See http://www.microsoft.com/technet/security/bulletin/MS09-008.mspx for more information.
