Descriptions
The internal DNS server in Samba 4.x before 4.0.18 does not check the QR field in the header section of an incoming DNS message before sending a response, which allows remote attackers to cause a denial of service (CPU and bandwidth consumption) via a forged response packet that triggers a communication loop, a related issue to CVE-1999-0103.
El servidor DNS interno en Samba 4.x anterior a 4.0.18 no comprueba el campo QR en la sección de cabecera de un mensaje DNS entrante antes de enviar una respuesta, lo que permite a atacantes remotos causar una denegación de servicio (consumo de CPU y ancho de banda) a través de un paquete de respuestas falsificado que provoca un bucle de comunicación, un problema relacionado con CVE-1999-0103.
