Severity Rating: Important
Revision Note: V1.1 (April 18, 2012): Added a link to Microsoft Knowledge Base Article 2647170 under Known Issues in the Executive Summary and corrected the bulletin replacement information for Windows Server 2003 Service Pack 2, Windows Server 2003 x64 Edition Service Pack 2, and Windows Server 2003 with SP2 for Itanium-based Systems. This is a bulletin change only. There were no changes to the detection.
Summary: This security update resolves a privately reported vulnerability in Microsoft Windows. The vulnerability could allow denial of service if a remote unauthenticated attacker sends a specially crafted DNS query to the target DNS server.
Bulletin details at Microsoft.com
The DNS server in Microsoft Windows Server 2003 SP2 and Server 2008 SP2, R2, and R2 SP1 does not properly handle objects in memory during record lookup, which allows remote attackers to cause a denial of service (daemon restart) via a crafted query, aka "DNS Denial of Service Vulnerability."
