CVE-2020-3999 – VMware Workstation SetGuestInfo Null Pointer Dereference Denial-of-Service Vulnerability
https://notcve.org/view.php?id=CVE-2020-3999
VMware ESXi (7.0 prior to ESXi70U1c-17325551), VMware Workstation (16.x prior to 16.0 and 15.x prior to 15.5.7), VMware Fusion (12.x prior to 12.0 and 11.x prior to 11.5.7) and VMware Cloud Foundation contain a denial of service vulnerability due to improper input validation in GuestInfo. A malicious actor with normal user privilege access to a virtual machine can crash the virtual machine's vmx process leading to a denial of service condition. VMware ESXi (versiones 7.0 anteriores a ESXi70U1c-17325551), VMware Workstation (versiones 16.x anteriores a 16.0 y versiones 15.x anteriores a 15.5.7), VMware Fusion (versiones 12.x anteriores a 12.0 y versiones 11.x anteriores a 11.5.7) y VMware Cloud Foundation contienen una vulnerabilidad de denegación de servicio debido a una comprobación inapropiada de la entrada en GuestInfo. Un actor malicioso con acceso privilegiado de usuario normal para una máquina virtual puede bloquear el proceso vmx de la máquina virtual y causar una condición de denegación de servicio This vulnerability allows local attackers to create a denial-of-service condition 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 the SetGuestInfo RPC function. • https://www.vmware.com/security/advisories/VMSA-2020-0029.html • CWE-20: Improper Input Validation •
CVE-2020-4004
https://notcve.org/view.php?id=CVE-2020-4004
VMware ESXi (7.0 before ESXi70U1b-17168206, 6.7 before ESXi670-202011101-SG, 6.5 before ESXi650-202011301-SG), Workstation (15.x before 15.5.7), Fusion (11.x before 11.5.7) contain a use-after-free vulnerability in the XHCI USB controller. A malicious actor with local administrative privileges on a virtual machine may exploit this issue to execute code as the virtual machine's VMX process running on the host. VMware ESXi (versiones 7.0 anteriores a ESXi70U1b-17168206, versiones 6.7 anteriores a ESXi670-202011101-SG, versiones 6.5 anteriores a ESXi650-202011301-SG), Workstation (versiones 15.x anteriores a 15.5.7), Fusion (versiones 11.x anteriores a 11.5.7), contienen una vulnerabilidad de uso de la memoria previamente liberada en el controlador USB XHCI. Un actor malicioso con privilegios administrativos locales en una máquina virtual puede explotar este problema para ejecutar código como el proceso VMX de la máquina virtual que se ejecuta en el host • https://www.vmware.com/security/advisories/VMSA-2020-0026.html • CWE-416: Use After Free •
CVE-2020-3995
https://notcve.org/view.php?id=CVE-2020-3995
In VMware ESXi (6.7 before ESXi670-201908101-SG, 6.5 before ESXi650-202007101-SG), Workstation (15.x before 15.1.0), Fusion (11.x before 11.1.0), the VMCI host drivers used by VMware hypervisors contain a memory leak vulnerability. A malicious actor with access to a virtual machine may be able to trigger a memory leak issue resulting in memory resource exhaustion on the hypervisor if the attack is sustained for extended periods of time. En VMware ESXi (versiones 6.7 anteriores a ESXi670-201908101-SG, versiones 6.5 anteriores a ESXi650-202007101-SG), Workstation (versiones 15.x anteriores a 15.1.0), Fusion (versiones 11.x anteriores a 11.1.0), los controladores del host VMCI utilizados por los hipervisores de VMware contienen una vulnerabilidad de filtrado de memoria. Un actor malicioso con acceso a una máquina virtual puede desencadenar un problema de filtrado de memoria que resulte en el agotamiento de los recursos de memoria en el hipervisor si el ataque se mantiene durante períodos prolongados • https://www.vmware.com/security/advisories/VMSA-2020-0023.html • CWE-401: Missing Release of Memory after Effective Lifetime •
CVE-2020-3982 – VMware Workstation BDOOR_CMD_PATCH_ACPI_TABLES Time-Of-Check Time-Of-Use Privilege Escalation Vulnerability
https://notcve.org/view.php?id=CVE-2020-3982
VMware ESXi (7.0 before ESXi_7.0.1-0.0.16850804, 6.7 before ESXi670-202008101-SG, 6.5 before ESXi650-202007101-SG), Workstation (15.x), Fusion (11.x before 11.5.6) contain an out-of-bounds write vulnerability due to a time-of-check time-of-use issue in ACPI device. A malicious actor with administrative access to a virtual machine may be able to exploit this vulnerability to crash the virtual machine's vmx process or corrupt hypervisor's memory heap. VMware ESXi (versiones 7.0 anteriores a ESXi_7.0.1-0.0.16850804, versiones 6.7 anteriores a ESXi670-202008101-SG, versiones 6.5 anteriores a ESXi650-202007101-SG), Workstation (versiones 15.x), Fusion (versiones 11.x anteriores a de 11.5.6), contienen una vulnerabilidad de escritura fuera de límites debido a un problema time-of-check time-of-use en el dispositivo ACPI. Un actor malicioso con acceso administrativo a una máquina virtual puede ser capaz de explotar esta vulnerabilidad para bloquear el proceso vmx de la máquina virtual o corromper la pila de la memoria del hipervisor 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.
