hickory-net is vulnerable to Denial of Service (DoS)
30
Low Risk
This Affects:
hickory-netTL;DR
A logic error in the DS-fetch path of DNSSEC validation treats a transient, single failed DS lookup as a durable bogus verdict for an entire child zone. That synthetic bogus result is cached, so later validations short-circuit and return SERVFAIL without re-querying the parent for DS records. Resolution of the affected zone stays broken until the cache entry expires. The fix stops caching transient DS-fetch failures as bogus.
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
