MIME-Version: 1.0

Synopsis: Moderate: libvirt security, bug fix, and enhancement
update
Issue Date: 2013-02-21
CVE Numbers: CVE-2012-3411
--

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.
