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-2019-1464)
A denial of service vulnerability exists in Microsoft Word software when the software fails to properly handle objects in memory. An attacker who successfully exploited the vulnerability could cause a remote denial of service against a system. Exploitation of the vulnerability requires that a specially crafted document be sent to a vulnerable user. The security update addresses the vulnerability by correcting how Microsoft Word handles objects in memory. (CVE-2019-1461)
An information disclosure vulnerability exists in Microsoft Access software when the software fails to properly handle objects in memory. An attacker who successfully exploited this vulnerability could obtain information to further compromise the users system.
(CVE-2019-1400, CVE-2019-1463)
A remote code execution vulnerability exists in Microsoft PowerPoint 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-2019-1462)
