Debian 10: DLA-3457-1 Critical: maraDNS Ghost Domain and Termination Issues

debian lts
Calendar Grey June 19, 2023
Dist Debian Esm H88
Safeguard your Debian environment by implementing the recent maradns patch that tackles significant vulnerabilities and risks.
MaraDNS is a small and lightweight cross-platform open-source DNS server

Summary

CVE-2022-30256

A revoked domain name (so called "Ghost" domain name) can still be
resolvable for a long time by staying in the cache longer than
max_ttl allows. "Ghost" domain names includes expired domains
and taken-down malicious domains.

CVE-2023-31137

The authoritative server in MaraDNS had an issue where it is
possible to remotely terminate the MaraDNS process with a
specialy crafted packet (so called "packet of death").

For Debian 10 buster, these problems have been fixed in version
2.0.13-1.2+deb10u1.

We recommend that you upgrade your maradns packages.
