Scientific Linux Security Update : libvirt on SL6.x i386/x86_64

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


Synopsis :

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

Description :

It was discovered that libvirt made certain invalid assumptions about
dnsmasq's command line options when setting up DNS masquerading for
virtual machines, resulting in dnsmasq incorrectly processing network
packets from network interfaces that were intended to be prohibited.
This update includes the changes necessary to call dnsmasq with a new
command line option, which was introduced to dnsmasq via
SLSA-2013:0277. (CVE-2012-3411)

In order for libvirt to be able to make use of the new command line
option (--bind-dynamic), updated dnsmasq packages need to be
installed. Refer to SLSA-2013:0277 for additional information.

After installing the updated packages, libvirtd must be restarted
('service libvirtd restart') for this update to take effect.
