VMware Tools < 11.1.1 Denial-of-Service Vulnerability (VMSA-2020-0014) (macOS)

low Nessus Plugin ID 137839
New! Plugin Severity Now Using CVSS v3

The calculated severity for Plugins has been updated to use CVSS v3 by default. Plugins that do not have a CVSS v3 score will fall back to CVSS v2 for calculating severity. Severity display preferences can be toggled in the settings dropdown.


An application installed on the remote MacOS / MacOSX host is affected by a denial-of-service vulnerability.


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.


Upgrade to VMwware Tools version 11.1.1 or later.
