Descriptions
Unbound before 1.4.13p2 attempts to free unallocated memory during processing of duplicate CNAME records in a signed zone, which allows remote DNS servers to cause a denial of service (daemon crash) via a crafted response.
Unbound antes de v1.4.13p2 intenta liberar memoria sin asignar durante el procesado de registros CNAME duplicados, lo que permite a servidores DNS remotos provocar una denegación de servicio (caída del demonio) a través de una respuesta modificada.
