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:14 relevant fixed versions and status.

Hickory DNS hickory-net 0.26.0-beta.1 before 0.26.2 and hickory-proto through 0.26.0-alpha.1 accept NSEC and NSEC3 records for DNSSEC nonexistence proofs when any other record with the same owner name passes signature validation. Attackers able to supply DNS responses can mix validly signed records with bogus same-name NSEC or NSEC3 records of different types in the authority section to forge nonexistence proofs.
