DESCRIPTION
According to the discoverer's report, Microsoft Word can accept an MS Access 2000 database as input for a mail merge operation. However, the database file could contain Visual Basic code that could be made to run when the database is opened by MS Word. Such code could perform actions on the system without the user's knowledge.
