Descriptions

Vulnerability in the Oracle VM VirtualBox component of Oracle Virtualization (subcomponent: Core). Supported versions that are affected are prior to 5.2.24 and prior to 6.0.2. Difficult to exploit vulnerability allows low 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 unauthorized access to critical data or complete access to all Oracle VM VirtualBox accessible data. CVSS 3.0 Base Score 5.6 (Confidentiality impacts). CVSS Vector: (CVSS:3.0/AV:L/AC:H/PR:L/UI:N/S:C/C:H/I:N/A:N).

Vulnerabilidad en el componente Oracle VM VirtualBox de Oracle Virtualization (subcomponente: Core). Las versiones compatibles que se han visto afectadas son las anteriores a la 5.2.24 y las anteriores a la 6.0.2. Una vulnerabilidad difícilmente explotable permite que un atacante con un bajo nivel de privilegios y con permisos de inicio de sesión en la infraestructura en la que se ejecuta Oracle VM VirtualBox comprometa la seguridad de Oracle VM VirtualBox. Aunque la vulnerabilidad está presente en Oracle VM VirtualBox, los ataques podrían afectar seriamente a productos adicionales. Los ataques exitosos a esta vulnerabilidad pueden resultar en un acceso no autorizado a datos críticos o un acceso completo a todos los datos accesibles de Oracle VM VirtualBox. CVSS 3.0 Base Score 5.6 (impactos en la confidencialidad). Vector CVSS: (CVSS:3.0/AV:L/AC:H/PR:L/UI:N/S:C/C:H/I:N/A:N).

This vulnerability allows local attackers to disclose sensitive information on vulnerable installations of Oracle VirtualBox. 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 crUnpackExtendGetAttribLocation 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 code in the context of the hypervisor.
