Scientific Linux Security Update : kvm on SL5.x x86_64

This script is Copyright (C) 2012-2013 Tenable Network Security, Inc.


Synopsis :

The remote Scientific Linux host is missing one or more security
updates.

Description :

KVM (Kernel-based Virtual Machine) is a full virtualization solution
for Linux on AMD64 and Intel 64 systems. KVM is a Linux kernel module
built for the standard Scientific Linux kernel.

It was found that the kvm_vm_ioctl_assign_device() function in the KVM
subsystem of a Linux kernel did not check if the user requesting
device assignment was privileged or not. A member of the kvm group on
the host could assign unused PCI devices, or even devices that were in
use and whose resources were not properly claimed by the respective
drivers, which could result in the host crashing. (CVE-2011-4347)

All KVM users should upgrade to these updated packages, which contain
backported patches to correct these issues.
