Descriptions

VMware Workstation (17.x) and VMware Fusion (13.x) contain a stack-based buffer-overflow vulnerability that exists in the functionality for sharing host Bluetooth devices with the virtual machine.

This vulnerability allows local attackers to escalate privileges on affected installations of VMware Workstation. An attacker must first obtain the ability to execute high-privileged code on the target guest system in order to exploit this vulnerability.
The specific flaw exists within the UHCI component. The issue results from the lack of proper validation of the length of user-supplied data prior to copying it to a fixed-length stack-based buffer. An attacker can leverage this vulnerability to escalate privileges and execute arbitrary code in the context of the hypervisor.
