This update addresses a flaw in the way Microsoft Office uses Visual Basic for Applications (VBA) to check document properties when opening a maliciously crafted document. This flaw could allow arbitrary code to run when a user opened a specially crafted document from an attacker. This update addresses that vulnerability so that files opened using VBA are handled appropriately.
