Descriptions
Vulnerability in the Oracle VM VirtualBox product of Oracle Virtualization (component: Core). Supported versions that are affected are Prior to 5.2.44, prior to 6.0.24 and prior to 6.1.12. Difficult to exploit vulnerability allows high privileged attacker with logon to the infrastructure where Oracle VM VirtualBox executes to compromise Oracle VM VirtualBox. While the vulnerability is in Oracle VM VirtualBox, attacks may significantly impact additional products. Successful attacks of this vulnerability can result in takeover of Oracle VM VirtualBox. CVSS 3.1 Base Score 7.5 (Confidentiality, Integrity and Availability impacts). CVSS Vector: (CVSS:3.1/AV:L/AC:H/PR:H/UI:N/S:C/C:H/I:H/A:H).
Vulnerabilidad en el producto de Oracle VM VirtualBox de Oracle Virtualization (componente: Core). Las versiones compatibles que están afectadas son anteriores a 5.2.44, anteriores a 6.0.24 y anteriores a 6.1.12. La vulnerabilidad difícil de explotar permite a un atacante muy privilegiado con inicio de sesión en la infraestructura donde se ejecuta Oracle VM VirtualBox comprometer a Oracle VM VirtualBox. Aunque la vulnerabilidad se encuentra en Oracle VM VirtualBox, los ataques pueden afectar significativamente a productos adicionales. Los ataques con éxito de esta vulnerabilidad pueden resultar en la toma de control de Oracle VM VirtualBox. CVSS 3.1 Puntuación Base 7.5 (Impactos de la Confidencialidad, Integridad y Disponibilidad). Vector CVSS: (CVSS:3.1/AV:L/AC:H/PR:H/UI:N/S:C/C:H/I:H/A:H)
This vulnerability allows local attackers to escalate privileges on affected installations of Oracle VirtualBox. 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 Transmit Message Descriptors in the implementation of PCnet virtual network interfaces. The issue results from the lack of proper validation of user-supplied data, which can result in a memory access past the end of an allocated buffer. An attacker can leverage this vulnerability to escalate privileges and execute code in the context of the hypervisor.
