The Microsoft Visio Products are missing a security update. It is, therefore, affected by a remote code execution vulnerability. The vulnerability exists when Microsoft Office improperly loads arbitrary type libraries. An attacker could then install programs; view, change, or delete data; or create new accounts with full user rights. Users whose accounts are configured to have fewer user rights on the system could be less impacted than users who operate with administrative user rights.
