"The remote Windows host is missing a security update. It is,
therefore, affected by multiple elevation of privilege
vulnerabilities :

  - An elevation of privilege vulnerability exists in the
    Windows Kernel API due to improper enforcement of
    permissions. A local attacker can exploit this, via a
    specially crafted application, to run processes in an
    elevated context. (CVE-2017-0050)

  - An elevation of privilege vulnerability exists in the
    Windows Transaction Manager due to improper handling of
    objects in memory. A local attacker can exploit this,
    via a specially crafted application, to run processes in
    an elevated context. (CVE-2017-0101)

  - An elevation of privilege vulnerability exists due to a
    failure to check the length of a buffer prior to copying
    memory. A local attacker can exploit this, by copying a
    file to a shared folder or drive, to gain elevated 
    privileges. (CVE-2017-0102)

  - An elevation of privilege vulnerability exists in the
    Windows Kernel API due to improper handling of objects
    in memory. A local attacker can exploit this, via a
    specially crafted application, to gain elevated
    privileges. (CVE-2017-0103)");
