Descriptions
This vulnerability allows local attackers to escalate privileges on affected installations of xhyve. 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 e1000 virtual device. The issue results from the lack of proper validation of the length of user-supplied data prior to copying it to a stack-based buffer. An attacker can leverage this vulnerability to escalate privileges and execute arbitrary code in the context of the hypervisor. Was ZDI-CAN-15056.
Esta vulnerabilidad permite a atacantes locales escalar privilegios en las instalaciones afectadas de xhyve. Un atacante debe obtener primero la capacidad de ejecutar código con altos privilegios en el sistema invitado de destino para poder explotar esta vulnerabilidad. El fallo específico se presenta en el dispositivo virtual e1000. El problema resulta de la falta de comprobación apropiada de la longitud de los datos suministrados por el usuario antes de copiarlos en un búfer en la región stack de la memoria. Un atacante puede aprovechar esta vulnerabilidad para escalar privilegios y ejecutar código arbitrario en el contexto del hipervisor. Era ZDI-CAN-15056
