Scientific Linux Security Update : kvm on SL 5.4 x86_64

This script is Copyright (C) 2012-2014 Tenable Network Security, Inc.

Synopsis :

The remote Scientific Linux host is missing one or more security

Description :

A flaw was found in the way QEMU-KVM handled erroneous data provided
by the Linux virtio-net driver, used by guest operating systems. Due
to a deficiency in the TSO (TCP segment offloading) implementation, a
guest's virtio-net driver would transmit improper data to a certain
QEMU-KVM process on the host, causing the guest to crash. A remote
attacker could use this flaw to send specially crafted data to a
target guest system, causing that guest to crash. (CVE-2010-0741)

The following procedure must be performed before this update will take
effect :

1) Stop all KVM guest virtual machines.

2) Either reboot the hypervisor machine or, as the root user, remove
(using 'modprobe -r [module]') and reload (using 'modprobe [module]')
all of the following modules which are currently running (determined
using 'lsmod'): kvm, ksm, kvm-intel or kvm-amd.

3) Restart the KVM guest virtual machines.
