  - An elevation of privilege vulnerability exists when
    Microsoft Outlook does not validate attachment headers
    properly. An attacker who successfully exploited the
    vulnerability could send an email with hidden
    attachments that would be opened or executed once a
    victim clicks a link within the email. Note that this
    does not bypass attachment filters, so blocked
    attachments will still be excluded.  (CVE-2018-8244)");
