Corrective updates have been released for stable branches of BIND DNS Server 9.16.28 and 9.18.3, along with a new release of the experimental branch 9.19.1. Versions 9.18.3 and 9.19.1 address a vulnerability (CVE-2022-1183) in the DNS-over-HTTPS mechanism, supported since branch 9.18. This vulnerability can lead to the unexpected termination of the named process if the TLS connection to the HTTP-based handler is prematurely closed. The issue only affects servers<\/a>servers handling DNS over HTTPS (DoH) requests. Servers that receive requests via DNS over TLS (DoT) and do not use DoH are not affected by the issue. <\/p>\n

Version 9.18.3 also introduces several functional improvements. Support for the second version of the zone catalog (\"Catalog Zones\"), defined in the fifth draft of the IETF specification, has been added. The zone catalog offers a new method for maintaining secondary DNS servers, where instead of defining individual records for each secondary zone on the secondary server, a transfer of a specific set of secondary zones is organized between the primary and secondary servers. Thus, by configuring the catalog transfer in a manner similar to the transfer of individual zones, zones created on the primary server that are marked as included in the catalog will be automatically created on the secondary server without the need to modify configuration files. <\/p>\n

The new version also adds support for extended error codes \"Stale Answer\" and \"Stale NXDOMAIN Answer\", which are issued when a stale answer is returned from the cache. Verification of external responses has been integrated into named and dig. for TLS certificates<\/a>, which can be used to organize strict or cooperative authentication based on TLS (RFC 9103).
