The Microsoft Outlook application installed on the remote host is missing a security update. It is, therefore, affected by the following vulnerability :

  • 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-2018-8587)
