VMware Workstation 15.x < 15.5.7 DoS (VMSA-2020-0029)

medium Nessus Plugin ID 144852
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.


A virtualization application installed on the remote host is affected by a DoS vulnerability


The version of VMware Workstation installed on the remote host is 15.x prior to 15.5.7. 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.


Update to VMware Workstation version 15.5.7, 16, or later.
