Descriptions

Xen 4.2.x and 4.3.x, when using Intel VT-d and a PCI device has been assigned, does not clear the flag that suppresses IOMMU TLB flushes when unspecified errors occur, which causes the TLB entries to not be flushed and allows local guest administrators to cause a denial of service (host crash) or gain privileges via unspecified vectors.

En Xen 4.2.x y 4.3.x, al utilizar Intel VT-d y un dispositivo PCI asignado, no borra el indicador que suprime vocados de IOMMU TLB cuando se producen errores no especificados, que hace que entradas de la TLB no sean eliminadas y permite a los locales administradores de invitados para causar una denegación de servicio (caída de host) o ganar privilegios a través de vectores no especificados.
