Descriptions
Heap-based buffer overflow in dnsmasq before 2.78 allows remote attackers to cause a denial of service (crash) or execute arbitrary code via a crafted IPv6 router advertisement request.
Un desbordamiento de búfer basado en memoria dinámica (heap) en dnsmasq en versiones anteriores a la 2.78 permite a los atacantes provocar una denegación de servicio (cierre inesperado) o ejecutar código arbitrario mediante una petición manipulada de anuncio de router IPv6.
A heap buffer overflow was discovered in dnsmasq in the IPv6 router advertisement (RA) handling code. An attacker on the local network segment could send crafted RAs to dnsmasq which would cause it to crash or, potentially, execute arbitrary code. This issue only affected configurations using one of these options: enable-ra, ra-only, slaac, ra-names, ra-advrouter, or ra-stateless.
Dnsmasq versions prior to 2.78 suffers from a heap-based overflow vulnerability.
