CVE-2013-4329 Information

Description

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.
