"The version of VMware Workstation installed on the remote Linux host
is 12.x prior to 12.5.7. It is, therefore, affected by the following
vulnerabilities:

  - A remote code execution vulnerability exists in VMware
    workstation within the SVGA device. An attacker with
    user access can exploit this to execute arbitrary
    code. (CVE-2017-4924)

  - A denial of service vulnerability exists in VMware
    workstation due to a NULL pointer deference when
    handling guest RPC requests. An attacker with guest
    access can exploit this to crash their VMs.
    NOTE: This vulnerability only affects VMware
    Workstation 12.5.2 and below. (CVE-2017-4925)");
