Hickory DNS before 0.26.0-beta.1 DNSSEC Validation Bypass via Non-IN Class Records
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…

Hickory DNS 0.25.0 through 0.26.0-alpha.1 DNSSEC Bogus Answer Cache Poisoning
The validating recursor in Hickory DNS hickory-recursor 0.25.0 through 0.26.0-alpha.1, hickory-resolver 0.26.0-alpha.1 before 0.26.2, and hickory-net 0.26.0-beta.1 before 0.26.2 caches DNSSEC-bogus answers using the untrusted, attacker-supplied record TTL (ca…

Hickory DNS DNSSEC Validation Cache Poisoning via Transient DS-Fetch Errors
Hickory DNS hickory-proto 0.25.0-alpha.1 through 0.26.0-alpha.1 and hickory-net before 0.26.2 contain a logic bug in DnssecDnsHandle's DS-fetch path that caches transient DS lookup errors as Bogus DNSSEC validation verdicts. An attacker who induces a SERVFAIL…

Hickory DNS 0.25.0 through 0.25.2 Missing Bailiwick Filtering on Negative Responses
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-bail…

Hickory DNS 0.25.0 before 0.26.2 DNSSEC Validation Bypass via SOA Record
The validating recursive resolver and validating forwarder in Hickory DNS (hickory-server) 0.25.0 before 0.26.2 do not check whether the SOA record passed DNSSEC validation when assembling NXDOMAIN or NODATA responses. An attacker able to supply forged DNS re…

Hickory DNS 0.26.0-beta.1 before 0.26.2 DNSSEC Validation Bypass via Wildcard Expansion
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 re…

Hickory DNS 0.26.0 before 0.26.2 Response Validation Bypass via QDCOUNT=0
Hickory DNS hickory-net 0.26.0 before 0.26.2 and hickory-proto 0.25.0 through 0.25.2 skip the check that a UDP response's question section matches the query when the response has an empty question section (QDCOUNT=0), and also skip the case-randomization chec…
