script_tag(name:"insight", value:"The libvirt library is a C API for managing and interacting with the
virtualization capabilities of Linux and other operating systems. In
addition, libvirt provides tools for remote management of virtualized
systems.
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 RHSA-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
RHSA-2013:0277 for additional information.
These updated libvirt packages include numerous bug fixes and enhancements.
Space precludes documenting all of these changes in this advisory. Users
are directed to the Red Hat Enterprise Linux 6.4 Technical Notes, linked
to in the References, for information on the most significant of these
changes.
All users of libvirt are advised to upgrade to these updated packages,
which fix these issues and add these enhancements. After installing the
updated packages, libvirtd must be restarted ('service libvirtd restart')
for this update to take effect.");
