CVE-2022-1183

Destroying a TLS session early causes assertion failure

Published May 19, 2022 CVSS 3.1 · 7.5 High EPSS 6.2% KEV · Not listed
Description
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.
