There is no fixed version for Echo:latest rust-hickory-proto.

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-proto before 0.26.0-beta.1 and hickory-net before 0.26.2 contain a DNSSEC validation bypass because verify_rrsets() ignores DNS class when partitioning RRsets, so non-IN records skip signature verification yet are marked secure when the IN records verify. Attackers able to supply DNS responses can include forged CH or HS class records, including DS records, to authenticate any DNSKEY and forge child zone responses.
