Description
Description
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 responses can have a forged SOA record returned to clients with the AD bit set, misleading clients that rely on the server's DNSSEC validation.
