Descriptions

An issue has been found in PowerDNS before 3.4.11 and 4.0.2, and PowerDNS recursor before 4.0.4, allowing an attacker in position of man-in-the-middle to alter the content of an AXFR because of insufficient validation of TSIG signatures. A missing check of the TSIG time and fudge values was found in AXFRRetriever, leading to a possible replay attack.

Se ha descubierto un problema en PowerDNS en versiones anteriores a la 3.4.11 y 4.0.2, y PowerDNS recursor en versiones anteriores a la 4.0.4, lo que permite que un atacante en posición Man-in-the-Middle (MitM) altere el contenido de un AXFR debido a una validación insuficiente de firmas TSIG. La falta de una comprobación de los valores time y fudge de TSIG se encontró en AXFRRetriever, lo que podría conducir a un ataque de reproducción.
