"The version of VMware Tools installed on the remote MacOS/MacOSX host
is prior to 11.1.1. It is, therefore, affected by a denial-of-service vulnerability in 
the Host-Guest File System (HGFS) implementation. Successful exploitation of this issue 
may allow attackers with non-admin privileges on guest macOS virtual machines to create 
a denial-of-service condition on their own VMs.

Note that Nessus has not tested for these issues but has instead
relied only on the application's self-reported version number.");
