"The version of VMware Player installed on the remote host is version
7.x prior to 7.1.2. It is, therefore, affected by a guest privilege escalation
vulnerability in the Shared Folders (HGFS) feature due to improper
validation of user-supplied input. A local attacker can exploit this
to corrupt memory, resulting in an elevation of privileges.");

Note that VMware Tools in any Windows-based guests that use the Shared
Folders (HGFS) feature must also be updated to completely mitigate the
vulnerability.");
