The Debian security team deemed this advisory irrelevant for Debian:10.
NVD Description
Note: Versions mentioned in the description apply only to the upstream pdns-recursor package and not the pdns-recursor package as distributed by Debian.
A remote attacker might be able to cause infinite recursion in PowerDNS Recursor 4.8.0 via a DNS query that retrieves DS records for a misconfigured domain, because QName minimization is used in QM fallback mode. This is fixed in 4.8.1.
