CVE-2022-33992:

DNRD (aka Domain Name Relay Daemon) 2.20.3 forwards and caches DNS queries with the CD (aka checking disabled) bit set to 1. This leads to disabling of DNSSEC protection provided by upstream resolvers.

CVE-2022-33993:

Misinterpretation of special domain name characters in DNRD (aka Domain Name Relay Daemon) 2.20.3 leads to cache poisoning because domain names and their associated IP addresses are cached in their misinterpreted form.

URL says upstream's dead, so I guess we just need to treeclean.
