Descriptions

An issue has been found in the DNSSEC validation component of PowerDNS Recursor from 4.0.0 and up to and including 4.0.6, where the signatures might have been accepted as valid even if the signed data was not in bailiwick of the DNSKEY used to sign it. This allows an attacker in position of man-in-the-middle to alter the content of records by issuing a valid signature for the crafted records.

Se ha descubierto un problema en el componente de validación DNSSEC de PowerDNS Recursor, desde la versión 4.0.0 hasta la versión 4.0.6, también incluida, en el que las firmas podrían haber sido aceptadas como válidas incluso aunque los datos firmados no estuvieran en el territorio del DNSKEY empleado para firmarlo. Esto permite que un atacante en posición Man-in-the-Middle (MitM) altere el contenido de los registros enviando una firma válida para los registros manipulados.
