Package : maradns
Version : 2.0.13-1.2+deb10u1
CVE ID : CVE-2022-30256 CVE-2023-31137
Debian Bug : 1033252 1035936
MaraDNS is a small and lightweight cross-platform open-source DNS server.
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.
