Description Andrej Nemec 2018-09-10 15:33:38 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 of the TSIG time and fudge values was found in AXFRRetriever, leading to a possible replay attack.
