The Microsoft Office Products are missing security updates. It is, therefore, affected by multiple vulnerabilities:
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-2020-0759)
A security feature bypass vulnerability exists in Microsoft Outlook software when it improperly handles the parsing of URI formats. The security feature bypass by itself does not allow arbitrary code execution.
However, to successfully exploit the vulnerability, an attacker would have to use it in conjunction with another vulnerability, such as a remote code execution vulnerability, to take advantage of the security feature bypass vulnerability and run arbitrary code. (CVE-2020-0696)
An elevation of privilege vulnerability exists in Microsoft Office OLicenseHeartbeat task, where an attacker who successfully exploited this vulnerability could run this task as SYSTEM. (CVE-2020-0697)
