Descriptions
Vulnerability in the Oracle VM VirtualBox product of Oracle Virtualization (component: Core). Supported versions that are affected are Prior to 5.2.36, prior to 6.0.16 and prior to 6.1.2. Easily exploitable 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 6.5 (Confidentiality impacts). CVSS Vector: (CVSS:3.0/AV:L/AC:L/PR:L/UI:N/S:C/C:H/I:N/A:N).
Vulnerabilidad en el producto Oracle VM VirtualBox de Oracle Virtualization (componente: Core). Las versiones compatibles que están afectadas son las versiones anteriores a la versión 5.2.36, anteriores a la versión 6.0.16 y anteriores a la versión 6.1.2. Una vulnerabilidad fácilmente explotable permite a un atacante poco privilegiado con inicio de sesión en la infraestructura donde se ejecuta Oracle VM VirtualBox comprometer a Oracle VM VirtualBox. Aunque la vulnerabilidad ocurre en Oracle VM VirtualBox, los ataques pueden impactar significativamente a productos adicionales. Los ataques con éxito de esta vulnerabilidad pueden resultar en un acceso no autorizado a datos críticos o en un acceso completo a todos los datos accesibles de Oracle VM VirtualBox. CVSS 3.0 Puntaje Base 6.5 (Impactos en la Confidencialidad). Vector CVSS: (CVSS:3.0/AV:L/AC:L/PR:L/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 low-privileged code on the target guest system in order to exploit this vulnerability.
The specific flaw exists within the shader_glsl_texbem function. 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.
