Microsoft Security Bulletin MS08-017 - Critical

Vulnerabilities in Microsoft Office Web Components Could Allow Remote Code Execution (933103)

Published: | Updated:

Version: 1.3

General Information

Executive Summary

This critical update resolves two privately reported vulnerabilities in Microsoft Office Web Components. These vulnerabilities could allow remote code execution if a user viewed a specially crafted Web page. An attacker who successfully exploited this vulnerability could take complete control of an affected system. An attacker could then install programs; view, change, or delete data; or create new accounts with full user rights. Users whose accounts are configured to have fewer user rights on the system could be less impacted than users who operate with administrative user rights.

This is a critical security update for implementations of Microsoft Office Web Components 2000 on supported editions of Microsoft Office 2000 Service Pack 3, Microsoft Office XP Service Pack 3, Visual Studio .NET 2002 Service Pack 1, Visual Studio .NET 2003 Service Pack 1, Microsoft BizTalk Server 2000 and Microsoft BizTalk Server 2002, Microsoft Commerce Server 2000, and Internet Security and Acceleration Server 2000 Service Pack 2. For more information, see the subsection, Affected and Non-Affected Software, in this section.

This security update addresses the security vulnerabilities by modifying the way that Microsoft Office Web Components handles error conditions and manages memory resources, and by setting the kill bits for Microsoft Office Spreadsheet 2000 controls. For more information about the vulnerabilities, see the Frequently Asked Questions (FAQ) subsection for the specific vulnerability entry under the next section, Vulnerability Information.
