Descriptions

This vulnerability allows local attackers to disclose sensitive information on affected installations of Parallels Desktop 17.1.1 (51537). 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 Parallels Tools component. 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 in conjunction with other vulnerabilities to escalate privileges and execute arbitrary code in the context of the kernel. Was ZDI-CAN-16653.

Esta vulnerabilidad permite a atacantes locales divulgar información confidencial en las instalaciones afectadas de Parallels Desktop versión 17.1.1 (51537). Un atacante debe obtener primero la capacidad de ejecutar código poco privilegiado en el sistema huésped de destino para poder explotar esta vulnerabilidad. El fallo específico se presenta en el componente Parallels Tools. El problema resulta de una falta de comprobación apropiada de un valor suministrado por el usuario antes de desreferenciarlo como puntero. Un atacante puede aprovechar esto junto con otras vulnerabilidades para escalar privilegios y ejecutar código arbitrario en el contexto del kernel. Era ZDI-CAN-16653
