It is, therefore, affected by the following vulnerability :

  - A remote code execution vulnerability exists when
    Microsoft Access fails to properly handle objects in
    memory. An attacker who successfully exploited the
    vulnerability could take control of the affected system.
    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.
