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 that the TSIG record is the last one, leading to the possibility of parsing records that are not covered by the TSIG signature.

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. Falta una comprobación de que el registro TSIG es el último, lo que conduce a la posibilidad de que se analicen registros que no están cubiertos por la firma TSIG.
