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-2019-1297)

  - 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-2019-1263)");

  - A remote code execution vulnerability exists when the

    execute arbitrary commands. In a file-sharing attack
    scenario, an attacker could provide a specially crafted
    document file designed to exploit the vulnerability, and
