CVSS: 8.2EPSS: 0%CPEs: 180EXPL: 0CVE-2020-3962 – VMware Workstation SVGA DXInvalidateContext Use-After-Free Privilege Escalation Vulnerability
https://notcve.org/view.php?id=CVE-2020-3962
VMware ESXi (7.0 before ESXi_7.0.0-1.20.16321839, 6.7 before ESXi670-202004101-SG and 6.5 before ESXi650-202005401-SG), Workstation (15.x before 15.5.5), and Fusion (11.x before 11.5.5) contain a use-after-free vulnerability in the SVGA device. A malicious actor with local access to a virtual machine with 3D graphics enabled may be able to exploit this vulnerability to execute code on the hypervisor from a virtual machine. VMware ESXi (versiones 7.0 anteriores a ESXi_7.0.0-1.20.16321839, versiones 6.7 anteriores a ESXi670-202004101-SG y versiones 6.5 anteriores a ESXi650-202005401-SG), Workstation (versiones 15.x anteriores a 15.5.5) y Fusion (versiones 11.x anteriores a 11.5. 5), contienen una vulnerabilidad de uso de la memoria previamente liberada en el dispositivo SVGA. Un actor malicioso con acceso local a una máquina virtual con gráficos 3D habilitados puede ser capaz de explotar esta vulnerabilidad para ejecutar código en el hipervisor desde una máquina virtual 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 handling of the SVGA DXInvalidateContext command. • https://www.vmware.com/security/advisories/VMSA-2020-0015.html https://www.zerodayinitiative.com/advisories/ZDI-20-785 • CWE-416: Use After Free •

https://notcve.org/view.php?id=CVE-2020-3969
VMware ESXi (7.0 before ESXi_7.0.0-1.20.16321839, 6.7 before ESXi670-202004101-SG and 6.5 before ESXi650-202005401-SG), Workstation (15.x before 15.5.5), and Fusion (11.x before 11.5.5) contain an off-by-one heap-overflow vulnerability in the SVGA device. A malicious actor with local access to a virtual machine with 3D graphics enabled may be able to exploit this vulnerability to execute code on the hypervisor from a virtual machine. Additional conditions beyond the attacker's control must be present for exploitation to be possible. VMware ESXi (versiones 7.0 anteriores a ESXi_7.0.0-1.20.16321839, versiones 6.7 anteriores a ESXi670-202004101-SG y versiones 6.5 anteriores a ESXi650-202005401-SG), Workstation (versiones 15.x anteriores a 15.5.5) y Fusion (versiones 11.x anteriores a 11.5. 5), contienen una vulnerabilidad de desbordamiento de pila por un paso en el dispositivo SVGA. Un actor malicioso con acceso local a una máquina virtual con gráficos 3D habilitados puede ser capaz de explotar esta vulnerabilidad para ejecutar código en el hipervisor desde una máquina virtual. • https://www.vmware.com/security/advisories/VMSA-2020-0015.html https://www.zerodayinitiative.com/advisories/ZDI-20-786 • CWE-193: Off-by-one Error •
