"The Microsoft Word 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-2019-0585)

  - An information disclosure vulnerability exists when
    Microsoft Word macro buttons are used improperly. An
    attacker who successfully exploited this vulnerability
    could read arbitrary files from a targeted system.
    (CVE-2019-0561)");
