"The version of VMware Fusion installed on the remote macOS or Mac OS
X host is 11.0.x prior to 11.5.6. It is, therefore, affected by the
following vulnerabilities:

  - A time-of-check time-of-use flaw exists related to ACPI device
    handling that allows an authenticated administrator to leak
    memory from the vmx process. (CVE-2020-3981)

  - A time-of-check time-of-use flaw exists related to ACPI device
    handling that allows an authenticated administrator to crash the
    vmx process or corrupt the hypervisor's memory heap.
    (CVE-2020-3982)

  - An unspecified flaw exists related to the VMCI host drivers that
    allows an attacker having access to the virtual machine to cause
    denial of service conditions via resource exhaustion.
    (CVE-2020-3995)

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