CVE-2012-5634

Xen 4.2.x, 4.1.x, and 4.0, when using Intel VT-d for PCI passthrough, does not properly configure VT-d when supporting a device that is behind a legacy PCI Bridge, which allows local guests to cause a denial of service to other guests by injecting an interrupt...

VT-d interrupt remapping source validation flaw

ISSUE DESCRIPTION When passing a device which is behind a legacy PCI Bridge through to a guest Xen incorrectly configures the VT-d hardware. This could allow incorrect interrupts to be injected to other guests which also have passthrough devices. In a typical Xen system many devices are owned by...

Qubes OS Release Enhances Security Via Domain Isolation

With the deluge of malware and advanced attacks continuing unabated, security approaches that sandbox applications or isolate processes are garnering increased attention. Researcher Joanna Rutkowska and Invisible Things Lab were the latest to go in that direction with the official release on...

CVE-2011-1898

CVE-2011-1898 affects Xen (versions 4.1 before 4.1.1 and 4.0 before 4.0.2). When using PCI passthrough on Intel VT-d chipsets that lack interrupt remapping, a guest OS user can gain host OS privileges by using DMA to generate MSI interrupts via the interrupt injection registers. The provided docu...
