Descriptions

The xenlight library (libxl) in Xen 4.0.x through 4.2.x, when IOMMU is disabled, provides access to a busmastering-capable PCI passthrough device before the IOMMU setup is complete, which allows local HVM guest domains to gain privileges or cause a denial of service via a DMA instruction.

La librería xenlight (libxl) en Xen 4.0.x a 4.2.x, cuando IOMMU está desactivado, proporciona acceso a un dispositivo de paso PCI con capacidad de control de bus antes de que la configuración IOMMU se complete, lo cual permite a dominios locales HVM invitados obtener privilegios o causar denegación de servicio a través de una instrucción DMA.
