"The Microsoft Office or Outlook application installed on the remote
Windows host is missing a security update. It is, therefore, affected
by multiple vulnerabilities :

  - A security feature bypass vulnerability exists in
    Microsoft Office due to improper handling of
    user-supplied input. An unauthenticated, remote attacker
    can exploit this, by convincing a user to open and
    interact with a specially crafted document file, to
    bypass security measures and execute arbitrary commands.
    (CVE-2017-8571)

  - An information disclosure vulnerability exists in
    Microsoft Office due to improper handling of objects in
    memory. An unauthenticated, remote attacker can exploit
    this, by convincing a user to open a specially crafted
    document file, to disclose the contents of memory.
    (CVE-2017-8572)

  - A remote code execution vulnerability exists in
    Microsoft Outlook due to improper parsing of email
    messages. An unauthenticated, remote attacker can
    exploit this, with a specially crafted email message
    with a malicious attachment, to execute arbitrary code
    in the context of the current user. (CVE-2017-8663)");
