NVD Description

Note: Versions mentioned in the description apply only to the upstream bind9 package and not the bind9 package as distributed by Ubuntu. See How to fix? for Ubuntu:22.04 relevant fixed versions and status.

On vulnerable configurations, the named daemon may, in some circumstances, terminate with an assertion failure. Vulnerable configurations are those that include a reference to http within the listen-on statements in their named.conf. TLS is used by both DNS over TLS (DoT) and DNS over HTTPS (DoH), but configurations using DoT alone are unaffected. Affects BIND 9.18.0 -> 9.18.2 and version 9.19.0 of the BIND 9.19 development branch.
