Descriptions

Race condition in the grant table code in Xen 4.6.x through 4.9.x allows local guest OS administrators to cause a denial of service (free list corruption and host crash) or gain privileges on the host via vectors involving maptrack free list handling.

Una condición de carrera en el código de tabla de concesiones en Xen 4.6.x a 4.9.x permite que administradores invitados locales del sistema operativo provoquen una denegación de servicio (corrupción de lista libre y bloqueo del host) o que obtengan beneficios en el host mediante vectores que impliquen la gestión de lista libre de maptrack.

Multiple vulnerabilities have been found in Xen, the worst of which could allow for privilege escalation. Versions less than 4.9.1-r1 are affected.
