"The Microsoft Office Products are missing security updates. It is, therefore, affected by multiple vulnerabilities :

  - An information disclosure vulnerability exists when Microsoft Excel improperly discloses the contents of
    its memory. An attacker who exploited the vulnerability could use the information to compromise the users
    computer or data. (CVE-2020-1224)

  - 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-2020-1193,
    CVE-2020-1332, CVE-2020-1335, CVE-2020-1594)

  - A remote code execution vulnerability exists in Microsoft Word software when it fails to properly handle
    objects in memory. An attacker who successfully exploited the vulnerability could use a specially crafted
    file to perform actions in the security context of the current user. For example, the file could then take
    actions on behalf of the logged-on user with the same permissions as the current user. (CVE-2020-1218,
    CVE-2020-1338)");
