Descriptions

Vulnerability in the Oracle VM VirtualBox component of Oracle Virtualization (subcomponent: Core). The supported version that is affected is Prior to 5.2.16. Easily exploitable vulnerability allows unauthenticated attacker with logon to the infrastructure where Oracle VM VirtualBox executes to compromise Oracle VM VirtualBox. Successful attacks require human interaction from a person other than the attacker and 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 3.0 Base Score 8.6 (Confidentiality, Integrity and Availability impacts). CVSS Vector: (CVSS:3.0/AV:L/AC:L/PR:N/UI:R/S:C/C:H/I:H/A:H).

Vulnerabilidad en el componente Oracle VM VirtualBox de Oracle Virtualization (subcomponente: Core). La versión compatible afectada es la anterior a la 5.2.16. Una vulnerabilidad fácilmente explotable permite que un atacante sin autenticar 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. Para que los ataques tengan éxito, se necesita la participación de otra persona diferente del atacante y, 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 la toma de control de Oracle VM VirtualBox. CVSS 3.0 Base Score 8.6 (impactos en la confidencialidad, integridad y disponibilidad). Vector CVSS: (CVSS:3.0/AV:L/AC:L/PR:N/UI:R/S:C/C:H/I:H/A:H).

This vulnerability allows local attackers to execute arbitrary code 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 crUnpackPixelMapuiv method. The issue results from the lack of proper validation of a user-supplied value prior to dereferencing it as a pointer. An attacker can leverage this vulnerability to escalate privileges and execute code under the context of the hypervisor.
