Microsoft Security Bulletin MS09-064 - CriticalVulnerability in License Logging Server Could Allow Remote Code Execution (974783)Published: November 10, 2009 Version: 1.0 General InformationExecutive SummaryThis security update resolves a privately reported vulnerability in Microsoft Windows 2000. The vulnerability could allow remote code execution if an attacker sent a specially crafted network message to a computer running the License Logging Server. An attacker who successfully exploited this vulnerability could take complete control of the system. Firewall best practices and standard default firewall configurations can help protect networks from attacks that originate outside the enterprise perimeter. This security update is rated Critical for Microsoft Windows 2000. For more information, see the subsection, Affected and Non-Affected Software, in this section. The security update addresses the vulnerability by changing the way the License Logging service validates a specific field inside the RPC packet. For more information about the vulnerability, see the Frequently Asked Questions (FAQ) subsection for the specific vulnerability entry under the next section, Vulnerability Information. Recommendation. The majority of customers have automatic updating enabled and will not need to take any action because this security update will be downloaded and installed automatically. Customers who have not enabled automatic updating need to check for updates and install this update manually. For information about specific configuration options in automatic updating, see Microsoft Knowledge Base Article 294871. For administrators and enterprise installations, or end users who want to install this security update manually, Microsoft recommends that customers apply the update immediately using update management software, or by checking for updates using the Microsoft Update service.
