CVE-2020-3990 – VMware Workstation ThinPrint TTCHeader Integer Overflow Information Disclosure Vulnerability
https://notcve.org/view.php?id=CVE-2020-3990
VMware Workstation (15.x) and Horizon Client for Windows (5.x before 5.4.4) contain an information disclosure vulnerability due to an integer overflow issue in Cortado ThinPrint component. A malicious actor with normal access to a virtual machine may be able to exploit this issue to leak memory from TPView process running on the system where Workstation or Horizon Client for Windows is installed. Exploitation is only possible if virtual printing has been enabled. This feature is not enabled by default on Workstation but it is enabled by default on Horizon Client. VMware Workstation (versión 15.x) y Horizon Client para Windows (versiones 5.x anteriores a 5.4.4), contienen una vulnerabilidad de divulgación de información debido a un problema de desbordamiento de enteros en el componente Cortado ThinPrint. • https://www.vmware.com/security/advisories/VMSA-2020-0020.html • CWE-125: Out-of-bounds Read CWE-190: Integer Overflow or Wraparound •
CVE-2018-6957
https://notcve.org/view.php?id=CVE-2018-6957
VMware Workstation (14.x before 14.1.1, 12.x) and Fusion (10.x before 10.1.1 and 8.x) contain a denial-of-service vulnerability which can be triggered by opening a large number of VNC sessions. Note: In order for exploitation to be possible on Workstation and Fusion, VNC must be manually enabled. VMware Workstation (versiones 14.x anteriores a la 14.1.1 y 12.x) y Fusion (10.x anteriores a la 10.1.1 y 8.x) contiene una vulnerabilidad de denegación de servicio (DoS) que se puede desencadenar al abrir un número excesivo de sesiones VNC. Nota: Para que su explotación sea posible en Workstation y Fusion, se debe habilitar VNC manualmente. • http://www.securityfocus.com/bid/103431 http://www.securitytracker.com/id/1040539 https://www.vmware.com/security/advisories/VMSA-2018-0008.html • CWE-772: Missing Release of Resource after Effective Lifetime •
CVE-2017-5753 – Multiple CPUs - 'Spectre' Information Disclosure
https://notcve.org/view.php?id=CVE-2017-5753
Systems with microprocessors utilizing speculative execution and branch prediction may allow unauthorized disclosure of information to an attacker with local user access via a side-channel analysis. Los sistemas con microprocesadores con ejecución especulativa y predicción de ramas podrían permitir la revelación no autorizada de información al atacante con acceso de usuario local mediante un análisis de un canal lateral. An industry-wide issue was found in the way many modern microprocessor designs have implemented speculative execution of instructions (a commonly used performance optimization). There are three primary variants of the issue which differ in the way the speculative execution can be exploited. Variant CVE-2017-5753 triggers the speculative execution by performing a bounds-check bypass. • https://www.exploit-db.com/exploits/43427 https://github.com/sachinthaBS/Spectre-Vulnerability-CVE-2017-5753- http://lists.opensuse.org/opensuse-security-announce/2018-01/msg00006.html http://lists.opensuse.org/opensuse-security-announce/2018-01/msg00007.html http://lists.opensuse.org/opensuse-security-announce/2018-01/msg00008.html http://lists.opensuse.org/opensuse-security-announce/2018-01/msg00014.html http://lists.opensuse.org/opensuse-security-announce/2018-01/msg00016.html http://nvidia.custhe • CWE-200: Exposure of Sensitive Information to an Unauthorized Actor CWE-203: Observable Discrepancy •
CVE-2017-4933
https://notcve.org/view.php?id=CVE-2017-4933
VMware ESXi (6.5 before ESXi650-201710401-BG), Workstation (12.x before 12.5.8), and Fusion (8.x before 8.5.9) contain a vulnerability that could allow an authenticated VNC session to cause a heap overflow via a specific set of VNC packets resulting in heap corruption. Successful exploitation of this issue could result in remote code execution in a virtual machine via the authenticated VNC session. Note: In order for exploitation to be possible in ESXi, VNC must be manually enabled in a virtual machine's .vmx configuration file. In addition, ESXi must be configured to allow VNC traffic through the built-in firewall. VMware ESXi (6.5 anteriores a ESXi650-201710401-BG), Workstation (12.x anteriores a la 12.5.8) y Fusion (8.x anteriores a la 8.5.9) contienen una vulnerabilidad que podría permitir que una sesión VNC autenticada provoque un desbordamiento de memoria dinámica (heap) mediante una serie específica de paquetes VNC, resultando en una corrupción de memoria dinámica. • http://www.securitytracker.com/id/1040024 http://www.securitytracker.com/id/1040025 https://www.vmware.com/security/advisories/VMSA-2017-0021.html • CWE-787: Out-of-bounds Write •
