Descriptions

BIRD Internet Routing Daemon 1.6.x through 1.6.7 and 2.x through 2.0.5 has a stack-based buffer overflow. The BGP daemon's support for RFC 8203 administrative shutdown communication messages included an incorrect logical expression when checking the validity of an input message. Sending a shutdown communication with a sufficient message length causes a four-byte overflow to occur while processing the message, where two of the overflow bytes are attacker-controlled and two are fixed.

BIRD Internet Routing Daemon versiones 1.6.x hasta 1.6.7 y versiones 2.x hasta 2.0.5, presenta un desbordamiento de búfer en la región stack de la memoria. El soporte del demonio BGP para los mensajes de comunicación de apagado administrativo RFC 8203 incluía una expresión lógica incorrecta cuando se comprueba la validez de un mensaje de entrada. El envío de una comunicación de apagado con una longitud de mensaje suficiente causa un desbordamiento de cuatro bytes mientras es procesado el mensaje, donde dos de los bytes del desbordamiento están controlados por el atacante y dos son fijados.
