"The version of VMware Fusion installed on the remote macOS or Mac OS X host is 11.x prior to 11.5.7. It is,
therefore, affected by a DoS vulnerability due to improper input validation in GuestInfo. A malicious actor with normal
user privilege access to a virtual machine can crash the virtual machine's vmx process leading to a denial of service
condition.

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