CVE-2022-1183

Destroying a TLS session early causes assertion failure

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.

Affects BIND 9.18.0 -> 9.18.2 and version 9.19.0 of the BIND 9.19 development branch.

Remediation

  • Upgrade to the patched release most closely related to your current version of BIND: BIND 9.18.3 or BIND 9.19.1.
