"The Microsoft Outlook application installed on the remote
host is missing security updates. It is, therefore, affected
by multiple vulnerabilities :

  - A remote code execution vulnerability exists in
    Microsoft Outlook 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-2019-1200)

  - An elevation of privilege vulnerability exists when
    Microsoft Outlook initiates processing of incoming
    messages without sufficient validation of the formatting
    of the messages. An attacker who successfully exploited
    the vulnerability could attempt to force Outlook to load
    a local or remote message store (over SMB).
    (CVE-2019-1204)");
