hickory-resolver is vulnerable to Improper Verification of Cryptographic Signature
75
High Risk
This Affects:
hickory-resolverTL;DR
With DNSSEC validation enabled, the resolver's lookup and lookup_ip APIs return a successful result even when validation determines the response is bogus. Callers must inspect per-record proof status, which is inconvenient and easy to miss, so bogus data is treated as valid. These APIs should return an error for bogus responses. The fix makes them surface validation failures as errors.
Who does this affect?
You are affected if you are using a version that falls within the vulnerable range and you have DNSSEC validation enabled and use the lookup or lookup_ip APIs
