Microsoft Security Bulletin MS11-058 MS11-058 - Critical : Vulnerabilities in DNS Server Could Allow Remote Code Execution (2562485) - Version: 1.2 Severity Rating: Critical 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.Release Date:2011-10-25
