Overview

Affected versions of this package are vulnerable to Infinite loop in the DnssecDnsHandle process. An attacker can cause the process to enter an unbounded loop and exhaust system memory by returning a DNS response with an authority section containing an SOA record that is not an ancestor of the queried name, triggering repeated allocations. This is only exploitable if the dnssec-ring or dnssec-aws-lc-rs feature is enabled and DNSSEC validation is configured.
