NVD Description

Note: Versions mentioned in the description apply only to the upstream rust-hickory-proto package and not the rust-hickory-proto package as distributed by Echo. See How to fix? for Echo:latest relevant fixed versions and status.

Hickory DNS hickory-net 0.26.0-beta.1 before 0.26.2 and hickory-proto 0.24.0 through 0.26.0-alpha.1 compare DNSKEY public keys against DNSSEC trust anchors without checking the DNSKEY record name, so an RRset made up only of trusted keys is accepted without RRSIG verification. Attackers able to spoof or control name server responses can replace a secure zone's DNSKEY RRset with the root zone's keys, and use a large TTL to keep it cached.
