Summary

[none]

Details

hickory-resolver versions before 0.26.2 fail to propagate bogus DNSSEC proof states through the Resolver::lookup() and Resolver::lookup_ip() APIs, allowing invalid records to be returned as successful results. Attackers controlling the answering zone or positioned on the network path can have forged DNS records accepted as validated, bypassing DNSSEC authentication checks.
