CVE-2022-1183 – Destroying a TLS session early causes assertion failure
https://notcve.org/view.php?id=CVE-2022-1183
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.
