Office File Validation is a security add-in for Office 2003 and 2007. Office File Validation is used to validate that Binary File Format files conform to the Microsoft Office File Format.
Office File Validation verifies that a particular binary file complies with the application’s expectations. Office File Validation can help prevent unknown binary file format attacks against Microsoft Office 97-2003 file formats.
When you open Microsoft Office 97-2003 binary file (such as .doc) the file is compared to a binary schema. If the file fails this validation, you are notified that the document could be considered to be compromised.
