CVE-2013-4329

Xen 4.0.x-4.2.x - Privilege Escalation or Denial of Service via DMA Instruction

Title source: llm

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.
