CVE-2013-1952

CVE-2013-1952 affects Xen 4.x when using Intel VT-d for bus-master PCI devices. The vulnerability is a flaw in validating the source while accessing a bridge device’s interrupt remapping table entries for MSI interrupts, which can allow a local guest domain to cause a denial of service via interr...

CVE-2013-1952

Xen 4.x, when using Intel VT-d for a bus mastering capable PCI device, does not properly check the source when accessing a bridge device's interrupt remapping table entries for MSI interrupts, which allows local guest domains to cause a denial of service interrupt injection via unspecified vector...

CVE-2013-1952: Improper Input Validation

VT-d interrupt remapping source validation flaw for bridges

ISSUE DESCRIPTION Interrupt remapping table entries for MSI interrupts set up by bridge devices did not get any source validation set up on them, allowing misbehaving or malicious guests to inject interrupts into the domain owning the bridges. In a typical Xen system bridge devices are owned by...

SuSE 11.2 Security Update : Xen (SAT Patch Number 7492)

XEN has been updated to fix various bugs and security issues : - XSA 36 To avoid an erratum in early hardware, the Xen AMD IOMMU code by default choose to use a single interrupt remapping table for the whole system.
