NVD Description

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

The recursive resolver in Hickory DNS hickory-recursor 0.25.0 through 0.25.2 and hickory-resolver 0.26.0 before 0.26.2 does not apply out-of-bailiwick filtering to negative responses. Attackers able to supply crafted negative responses can include out-of-bailiwick records to facilitate cache poisoning and more easily exploit other DNSSEC verification flaws.
