Revision Note: V1.2 (October 25, 2011): Announced a change to detection logic and corrected bulletin replacement information for some affected configurations. There were no changes to the security update files. See the Update FAQ for details.

Summary: This security update resolves two privately reported vulnerabilities in Windows DNS server. The more severe of these vulnerabilities could allow remote code execution if an attacker registers a domain, creates an NAPTR DNS resource record, and then sends a specially crafted NAPTR query to the target DNS server. Servers that do not have the DNS role enabled are not at risk.

Title: DNS NAPTR Query Vulnerability
Description: The DNS server in Microsoft Windows Server 2008 SP2, R2, and R2 SP1 does not properly handle NAPTR queries that trigger recursive processing, which allows remote attackers to execute arbitrary code via a crafted query, aka "DNS NAPTR Query Vulnerability."
