Descriptions

Vulnerability in the Oracle VM VirtualBox product of Oracle Virtualization (component: Core). Supported versions that are affected are Prior to 6.1.38. Easily exploitable 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 (scope change). Successful attacks of this vulnerability can result in unauthorized access to critical data or complete access to all Oracle VM VirtualBox accessible data. CVSS 3.1 Base Score 6.0 (Confidentiality impacts). CVSS Vector: (CVSS:3.1/AV:L/AC:L/PR:H/UI:N/S:C/C:H/I:N/A:N).

Una vulnerabilidad en el producto Oracle VM VirtualBox de Oracle Virtualization (componente: Core). Las versiones soportadas que están afectadas son anteriores a 6.1.38. Una vulnerabilidad explotable fácilmente permite a un atacante con altos privilegios y con acceso a la infraestructura en la que es ejecutado Oracle VM VirtualBox, comprometer a Oracle VM VirtualBox. Mientras la vulnerabilidad está en Oracle VM VirtualBox, los ataques pueden afectar significativamente a otros productos (cambio de alcance). Los ataques con éxito de esta vulnerabilidad pueden resultar en el acceso no autorizado a datos críticos o el acceso completo a todos los datos accesibles de Oracle VM VirtualBox. CVSS 3.1 Puntuación Base 6.0 (Impactos en la Confidencialidad). Vector CVSS: (CVSS:3.1/AV:L/AC:L/PR:H/UI:N/S:C/C:H/I:N/A:N)

This vulnerability allows local attackers to disclose sensitive information 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 sosendoob method. The issue results from the lack of proper validation of user-supplied data, which can result in a read past the end of an allocated object. An attacker can leverage this in conjunction with other vulnerabilities to execute arbitrary code in the context of the hypervisor.
