"value": "An exploitable denial-of-service vulnerability exists in the message-parsing functionality of Videolabs libmicrodns 0.1.0. When parsing mDNS messages in mdns_recv, the return value of the mdns_read_header function is not checked, leading to an uninitialized variable usage that eventually results in a null pointer dereference, leading to service crash. An attacker can send a series of mDNS messages to trigger this vulnerability."

Cuando se analiza los mensajes mDNS en mdns_recv, el valor de retorno de la funci\u00f3n mdns_read_header no es comprobado, conllevando a un uso de la variable no inicializada que finalmente resulta en una desreferencia del puntero null, conllevando a un bloqueo del servicio. Un atacante puede enviar una serie de mensajes mDNS para desencadenar esta vulnerabilidad."
