VMware Workstation SVGA Heap-based Buffer Overflow Privilege Escalation VulnerabilityZDI-17-235: March 30th, 2017
This vulnerability allows local attackers to execute arbitrary code on vulnerable installations of VMware Workstation. An attacker must first obtain the ability to execute low-privileged code on the target system in order to exploit this vulnerability.
The specific flaw exists within the handling of SVGA graphics. 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 elevate privileges and execute arbitrary code under the context of the hypervisor.
