VMware Workstation 15.x < 15.5.7 Use-after-free (VMSA-2020-0026)

high Nessus Plugin ID 143223

Language:

Synopsis

A virtualization application installed on the remote Windows host is affected by a use-after-free error.

Description

The version of VMware Workstation installed on the remote Windows host is 15.x prior to 15.5.7. It is, therefore, affected by a use-after-free error in the XHCI USB Controller. An unauthenticated, local attacker with administrative privileges on a virtual machine may exploit this issue to execute code as the virtual machine's VMX process running on the host.

Note that Nessus has not tested for this issue, but has instead relied only on the application's self-reported version number.

Solution

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