"The Microsoft SharePoint Server installed on the remote Windows host
is missing a security update. It is, therefore, affected by multiple
vulnerabilities :

  - Multiple remote code execution vulnerabilities exist in
    Microsoft Office due to improper handling of objects in
    memory. An unauthenticated, remote attacker can exploit
    these, by convincing a user to open a specially crafted
    document, to execute arbitrary code in the context of
    the current user. (CVE-2017-8509, CVE-2017-8511,
    CVE-2017-8512)

  - A remote code execution vulnerability exists in
    Microsoft PowerPoint due to improper handling of objects
    in memory. An unauthenticated, remote attacker can
    exploit this, by convincing a user to open a specially
    crafted file, to execute arbitrary code in the context
    of the current user. (CVE-2017-8513)

  - A reflective cross-site scripting (XSS) vulnerability
    exists in Microsoft SharePoint Server due improper
    validation of user-supplied input in web requests. An
    unauthenticated, remote attacker can exploit this, via a
    specially crafted request, to execute arbitrary script
    code in a user's browser session. (CVE-2017-8514)

  - An elevation of privilege vulnerability exists when
    Microsoft SharePoint Server does not properly sanitize 
    a specially crafted web request to an affected
    SharePoint server. An authenticated attacker could
    exploit the vulnerability by sending a specially crafted
    request to an affected SharePoint server. (CVE-2017-8551)");
