Debian DSA-5441-1: Critical Security Update for Maradns Denial of Service

Two vulnerbilities were found in maradns, an open source domain name
system (DNS) implementation, that may lead to denial of service and
unintended domain name resolution.

For the oldstable distribution (bullseye), these problems have been fixed
in version 2.0.13-1.4+deb11u1.

We recommend that you upgrade your maradns packages.

For the detailed security status of maradns please refer to
