📋 Description

DNSSEC validation in Hickory DNS hickory-net 0.26.0-beta.1 before 0.26.2 and hickory-proto through 0.26.0-alpha.1 does not distinguish NODATA responses from wildcard-expanded positive responses. For a query that should return NODATA in a zone with wildcard records, an attacker can combine an NSEC3 record matching the query name with a signed wildcard record into a bogus positive response that validation accepts.
