Descriptions
Dnsmasq before 2.63test1, when used with certain libvirt configurations, replies to requests from prohibited interfaces, which allows remote attackers to cause a denial of service (traffic amplification) via a spoofed DNS query.
Dnsmasq anterior a v2.63test1, cuando se usa con determinadas configuraciones en libvirt, contesta a las peticiones desde interfaces prohibidas, lo que permite a atacantes remotos provocar una denegación de servicios (amplificación de tráfico) a través de una petición DNS falsificada.
