Dnsmasq before 2.66test2, when used with certain libvirt configurations,
replies to queries from prohibited interfaces, which allows remote
attackers to cause a denial of service (traffic amplification) via spoofed
TCP based DNS queries. NOTE: this vulnerability exists because of an
incomplete fix for CVE-2012-3411.
