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.
