Descriptions

daemon/worker.c in Unbound 1.x before 1.4.10, when debugging functionality and the interface-automatic option are enabled, allows remote attackers to cause a denial of service (assertion failure and daemon exit) via a crafted DNS request that triggers improper error handling.

daemon/worker.c de Unbound 1.x anteriores a 1.4.10, cuando la funcionalidad de depuración de errores ("debugging") y la opción de "interface-automatic" están activadas, permite a atacantes remotos provocar una denegación de servicio (fallo en aserción y finalización del demonio) a través de una petición DNS modificada que provoca un manejo de error incorrecto.
