Introduction

Office File Validation (OFV) is a security feature that was introduced in Microsoft Office 2010. 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. In Office 2003 and in the 2007 Office system, you are prompted about the file status and can decide to cancel opening the file or to continue to open the file.
