Microsoft Security Bulletin MS08-067 – Critical
Vulnerability in Server Service Could Allow Remote Code Execution  
(958644)
Published: October 23, 2008

Version: 1.0

Executive Summary

This security update resolves a privately reported vulnerability in  
the Server service. The vulnerability could allow remote code  
execution if an affected system received a specially crafted RPC  
request. On Microsoft Windows 2000, Windows XP, and Windows Server  
2003 systems, an attacker could exploit this vulnerability without  
authentication to run arbitrary code. It is possible that this  
vulnerability could be used in the crafting of a wormable exploit.  
Firewall best practices and standard default firewall configurations  
can help protect network resources from attacks that originate outside  
the enterprise perimeter.

This security update is rated Critical for all supported editions of  
Microsoft Windows 2000, Windows XP, Windows Server 2003, and rated  
Important for all supported editions of Windows Vista and Windows  
Server 2008. For more information, see the subsection, Affected and  
Non-Affected Software, in this section.

The security update addresses the vulnerability by correcting the way  
that the Server service handles RPC requests. 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. Microsoft recommends that customers apply the update  
immediately.
