| 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. This security update is rated Critical for all supported editions of Microsoft Office Excel 2000 and rated Important for all supported editions of Microsoft Office Excel 2002, Microsoft Office Excel 2003, Microsoft Office Excel Viewer 2003, Microsoft Office Excel 2007, Microsoft Office Compatibility Pack , Microsoft Office Excel Viewer, and Microsoft Office SharePoint Server 2007. |
