Description: A remote code execution issue exists due to the way Microsoft Office Excel parses documents containing a specially crafted formula embedded inside a cell. This could allow an attacker to take complete control of an affected system, enabling them to install programs, view, change, or delete data, or create new accounts with full user rights in the context of the currently logged on user.

Recommendations: For Microsoft Office Excel 2002 SP3, 2003 SP3, and 2007 SP1 and SP2, update to a version that is not affected by this issue. For Office 2004 and 2008 for Mac, update to a version that is not affected by this issue. For Open XML File Format Converter for Mac, update to a version that is not affected by this issue.

For Office Compatibility Pack for Word, Excel, and PowerPoint 2007 File Formats SP1 and SP2, update to a version that is not affected by this issue. As a temporary workaround, consider avoiding the use of crafted formulas in Excel cells until a patch is available.
