Microsoft Security Bulletin MS13-001 - Critical

Vulnerability in Windows Print Spooler Components Could Allow Remote Code Execution (2769369)

Published:

Version: 1.0

General Information

Executive Summary

This security update resolves one privately reported vulnerability in Microsoft Windows. The vulnerability could allow remote code execution if a print server received a specially crafted print job. Firewall best practices and standard default firewall configurations can help protect networks from attacks that originate outside the enterprise perimeter. Best practices recommend that systems connected directly to the Internet have a minimal number of ports exposed.

This security update is rated Critical for all supported editions of Windows 7 and Windows Server 2008 R2. For more information, see the subsection, Affected and Non-Affected Software, in this section.

The security update addresses the vulnerability by correcting how the Windows Print Spooler handles specially crafted print jobs. 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. Most 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.
