Description Andrej Nemec 2018-09-10 15:35:18 UTC
An issue has been found in PowerDNS 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.
