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

  - An information disclosure vulnerability exists in
    Microsoft Office 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-2019-1402)

  - 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-2019-1448)

  - A security feature bypass vulnerability exists in the
    way that Office Click-to-Run (C2R) components handle a
    specially crafted file, which could lead to a standard
    user, any AppContainer sandbox, and Office LPAC
    Protected View to escalate privileges to SYSTEM.
    (CVE-2019-1449)

  - 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-2019-1446)");
