hickory-net is vulnerable to Improper Verification of Cryptographic Signature

Medium Risk
This Affects:
hickory-netTL;DR
The NSEC3 handler selects the closest encloser by hash equality alone and never inspects the type bitmap, so a parent-side ancestor-delegation NSEC3 at a zone cut is accepted as proof for names below the cut. The no-data arm has the same defect, authenticating absence of non-DS types at the cut owner. Using only genuinely signed parent records, an adversary can forge authenticated NXDOMAIN for names that exist in the child zone. The fix applies the ancestor-delegation exclusion.
