Severity Rating: Critical - Revision Note: V1.2 (October 29, 2008): Added entry to the section, Frequently Asked Questions (FAQ) Related to This Security Update, to explain any additional security features included in this update for Microsoft Office 2003 Service Pack 2. Added missing entries for Excel 2003 Service Pack 3 to the section, Detection and Deployment Tools and Guidance. Finally, corrected references to Windows Installer Redistributable in the section, Security Update Deployment. This is an informational change only. There were no changes to the security update binaries.Summary: This security update resolves three privately reported vulnerabilities in Microsoft Office Excel that could allow remote code execution if a user opens a specially crafted Excel file. An attacker who successfully exploited these vulnerabilities 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.
