"The version of VMware Workstation installed on the remote host is
12.x prior to 12.5.0. It is, therefore, affected by multiple
vulnerabilities :

  - A heap buffer overflow condition exists in Cortado
    ThinPrint due to improper validation of user-supplied
    input. An attacker on the guest can exploit this to
    cause a denial of service condition or the execution of
    arbitrary code on the host system. (CVE-2016-7081)

  - A memory corruption issue exists in Cortado Thinprint
    due to improper handling of specially crafted EMF files.
    An attacker on the guest can exploit this to cause a
    denial of service condition or the execution of
    arbitrary code on the host system. (CVE-2016-7082)

  - A memory corruption issue exists in Cortado Thinprint
    due to improper handling of TrueType fonts embedded in
    EMFSPOOL. An attacker on the guest can exploit this to
    cause a denial of service condition or the execution of
    arbitrary code on the host system. (CVE-2016-7083)

  - A memory corruption issue exists in Cortado Thinprint
    due to improper handling of specially crafted JPEG2000
    images. An attacker on the guest can exploit this to
    cause a denial of service condition or the execution of
    arbitrary code on the host system. (CVE-2016-7084)

  - A flaw exits due to improper loading of some dynamic
    link library (DLL) files that allows an attacker to load
    a DLL file and thereby execute arbitrary code.
    (CVE-2016-7085)

  - A flaw exists in the Workstation installer due to
    insecure loading of executables. An attacker can exploit
    this, via a crafted application named 'setup64.exe'
    inserted into the same directory as the installer, to
    execute arbitrary code. (CVE-2016-7086)");
