Name of the Vulnerable Software and Affected Versions Microsoft Excel versions 2002 SP3, 2003 SP3, 2007 SP2, and 2010 Office 2004 and 2008 for Mac Open XML File Format Converter for Mac Excel Viewer SP2 Office Compatibility Pack for Word, Excel, and PowerPoint 2007 File Formats SP2

Description A remote code execution issue exists in the way Microsoft Excel handles specially crafted Excel files, potentially allowing attackers to execute arbitrary code via a crafted 400h substream in an Excel file, triggering a stack-based buffer overflow. This could enable an attacker to take complete control of an affected system, install programs, view, change, or delete data, or create new accounts with full user rights.

Recommendations For Microsoft Excel 2002 SP3, 2003 SP3, 2007 SP2, and 2010, update to a newer version to mitigate the risk. For Office 2004 and 2008 for Mac, update to a newer version to mitigate the risk. For Open XML File Format Converter for Mac, update to a newer version to mitigate the risk. For Excel Viewer SP2, update to a newer version to mitigate the risk. For Office Compatibility Pack for Word, Excel, and PowerPoint 2007 File Formats SP2, update to a newer version to mitigate the risk.
