NVD Description

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

Hickory DNS hickory-proto through 0.26.0-alpha.1 and hickory-net 0.26.0-beta.1 before 0.26.2 contain a DNSSEC validation flaw that accepts a response as a positive answer when any valid RRset appears in the answer section, without checking that the RRset is responsive to the query. Attackers can supply signed but unrelated RRsets so that responses lacking matching records are validated as positive answers instead of as no-data responses.
