The Microsoft Office Products are missing security updates.
It is, therefore, affected by multiple vulnerabilities :
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-2020-0850, CVE-2020-0851, CVE-2020-0855, CVE-2020-0892)

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-2020-0852)
Remote code execution vulnerabilities exist in Microsoft products that utilize the FBX library when processing specially crafted 3D content. An attacker who successfully exploited these vulnerabilities could gain the same user rights as the local user.
