Description

This security bulletin contains information about 1 security vulnerability.


1) Configuration (CVE-ID: CVE-2012-5634)

The vulnerability allows a remote non-authenticated attacker to perform a denial of service (DoS) attack.

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.
