"The Microsoft Sharepoint Server installation on the remote
host is missing a security update. It is, therefore,
affected by the following vulnerability :

  - An information disclosure vulnerability exists when
    Microsoft Office software reads out of bound memory due
    to an uninitialized variable, which could disclose the
    contents of memory. An attacker who successfully
    exploited the vulnerability could view out of bound
    memory. Exploitation of the vulnerability requires that
    a user open a specially crafted file with an affected
    version of Microsoft Office software. The security
    update addresses the vulnerability by properly
    initializing the affected variable. (CVE-2018-8378)");
