Descriptions
Xen 4.0.x through 4.7.x mishandle x86 task switches to VM86 mode, which allows local 32-bit x86 HVM guest OS users to gain privileges or cause a denial of service (guest OS crash) by leveraging a guest operating system that uses hardware task switching and allows a new task to start in VM86 mode.
Xen 4.0.x hasta la versión 4.7.x administra mal los conmutadores de tareas x86 para el modo VM86, lo que permite a usuarios locales del SO invitado x86 HVM de 32-bit obtener privilegios o provocar una denegación de servicio (caída del SO invitado) aprovechando un sistema operativo invitado que utiliza conmutación de tareas de hardware y permite iniciar una una nueva tarea en modo VM86.
