Descriptions

An issue was discovered in Xen through 4.9.x allowing PV guest OS users to cause a denial of service (host OS crash) if shadow mode and log-dirty mode are in place, because of an incorrect assertion related to M2P.

Se ha descubierto un problema en Xen, hasta las versiones 4.9.x, que permite que los usuarios PV invitados del sistema operativo provoquen una denegación de servicio (cierre inesperado del host del sistema operativo) si se han establecido los modos shadow y log-dirty. Esto se debe a una aserción incorrecta relacionada con M2P.

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.
