CVE-2013-0198
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.
Does this matter?
Lower severity and a low EPSS score (2.79%). Track it; it rarely justifies an emergency change on its own.
