ZDI-20-786: VMware Workstation SVGA3D Command Heap Overflow Privilege Escalation Vulnerability
This vulnerability allows local attackers to escalate privileges on affected installations of VMware Workstation. An attacker must first obtain the ability to execute low-privileged code on the target guest system in order to exploit this vulnerability. The specific flaw exists within the implementation of SVGA3D commands. The issue results from the lack of proper validation of the length of user-supplied data prior to copying it to a heap-based buffer. An attacker can leverage this vulnerability to execute code in the context of the hypervisor.
