Description
Office 2010 allows developers to extend the UI with customization code that is included in a document or template. If the customization code is written by an inexperienced or malicious developer, it could limit the accessibility or availability of important application commands. Commands could also be added to launch macros containing malicious code. Office applications load any UI customization code included with a document or template when opening it.
