An attacker could then install     programs; view, change, or delete data; or create new accounts with full user rights. (CVE-2020-16954)

  - A remote code execution vulnerability exists when the Microsoft Office Access Connectivity Engine improperly     handles objects in memory. An attacker who successfully exploited this vulnerability could execute arbitrary     code on a victim system.(CVE-2020-16957)
