CVE-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 •
CVE-2020-3969 – VMware Workstation SVGA3D Command Heap Overflow Privilege Escalation Vulnerability
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 •
CVE-2020-3959
https://notcve.org/view.php?id=CVE-2020-3959
VMware ESXi (6.7 before ESXi670-202004101-SG and 6.5 before ESXi650-202005401-SG), VMware Workstation (15.x before 15.1.0) and VMware Fusion (11.x before 11.1.0) contain a memory leak vulnerability in the VMCI module. A malicious actor with local non-administrative access to a virtual machine may be able to crash the virtual machine's vmx process leading to a partial denial of service. VMware ESXi (versiones 6.7 anteriores a ESXi670-202004101-SG y versiones 6.5 anteriores a ESXi650-202005401-SG), VMware Workstation (versiones 15.x anteriores a 15.1.0) y VMware Fusion (versiones 11.x anteriores a 11.1.0), contienen una vulnerabilidad de fuga de la memoria en el módulo VMCI. Un agente malicioso con acceso no administrativo local a una máquina virtual puede ser capaz de bloquear el proceso vmx de la máquina virtual, conllevando a una denegación de servicio parcial. • https://www.vmware.com/security/advisories/VMSA-2020-0011.html • CWE-401: Missing Release of Memory after Effective Lifetime •
