  - A remote code execution vulnerability exists in
    Microsoft Office software when the software fails to
    properly handle objects in memory. An attacker who
    successfully exploited the vulnerability could run
    arbitrary code in the context of the current user. If
    the current user is logged on with administrative user
    rights, an attacker 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.  (CVE-2020-0991)

  - 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. An attacker could exploit this
    vulnerability by enticing a victim to open a specially
    crafted file. The update addresses the vulnerability by
    correcting the way the Microsoft Office Access
    Connectivity Engine handles objects in memory.
    (CVE-2020-0961)

  - A remote code execution vulnerability exists in
    Microsoft Excel software when the software fails to
    properly handle objects in memory. An attacker who
    successfully exploited the vulnerability could run
    arbitrary code in the context of the current user. If
    the current user is logged on with administrative user
    rights, an attacker 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.  (CVE-2020-0906, CVE-2020-0979)");
