| Package | Affected versions | Patched versions |
|---|---|---|
| authoritative | ≥ 4.0.0, < 4.0.2< 3.4.11 | 4.0.23.4.11 |
| recursor | ≥ 4.0.0, < 4.0.4< 3.7.4 | 4.0.43.7.4 |
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.
