Summary

Details

Hickory DNS hickory-net 0.26.0-beta.1 before 0.26.2 and hickory-proto through 0.26.0-alpha.1 perform insufficient checks on NSEC3 record names during DNSSEC verification, comparing only the hashed label without confirming the record belongs to the correct zone. Attackers can supply NSEC3 records from another zone with a matching hash label to forge DNSSEC nonexistence proofs.
