Descripción
Se ha descubierto una vulnerabilidad de desbordamiento de búfer en PowerDNS Recursor 3.1.3 y versiones anteriores. La vulnerabilidad reside en un error al manejar peticiones TCP DNS. La explotación de esta vulnerabilidad podría permitir a un atacante remoto ejecutar código arbitrario mediante peticiones TCP DNS especialmente construidas que impedirían a Recursor calcular la longitud de estas peticiones correctamente.
