Corrigerende updates zijn uitgebracht voor de stabiele versies van de DNS-server BIND 9.16.28 en 9.18.3, evenals een nieuwe release van de experimentele versie 9.19.1. In de versies 9.18.3 en 9.19.1 is een kwetsbaarheid (CVE-2022-1183) opgelost in de implementatie van de DNS-over-HTTPS mechanisme, dat ondersteund wordt vanaf versie 9.18. De kwetsbaarheid leidt tot een fout in het named-proces wanneer de TLS-verbinding naar de handler op basis van het HTTP-protocol voortijdig wordt verbroken. Het probleem betreft alleen servers<\/a>, servers die DNS over HTTPS (DoH) verzoeken verwerken. Servers die verzoeken via DNS over TLS (DoT) ontvangen en geen gebruik maken van DoH zijn niet getroffen door het probleem. <\/p>\n

In versie 9.18.3 zijn ook verschillende functionele verbeteringen toegevoegd. Ondersteuning voor de tweede versie van de zonecatalogus («Catalog Zones») is ge\u00efntroduceerd, zoals gedefinieerd in de vijfde conceptversie van de IETF-specificatie. De zonecatalogus biedt een nieuwe methode voor het onderhouden van secundaire DNS-servers, waarin in plaats van afzonderlijke records voor elke secundaire zone op de secundaire server, een overdracht van een bepaalde set secundaire zones tussen de primaire en secundaire servers wordt georganiseerd. Dit betekent dat door het instellen van de catalogusoverdracht, vergelijkbaar met de overdracht van afzonderlijke zones, de zones die op de primaire server zijn aangemaakt en gemarkeerd als behorend tot de catalogus, automatisch op de secundaire server zullen worden aangemaakt zonder dat het configuratiebestand hoeft te worden aangepast. <\/p>\n

In de nieuwe versie is er ook ondersteuning toegevoegd voor de uitgebreide foutcodes «Stale Answer» en «Stale NXDOMAIN Answer», die worden geretourneerd wanneer een verouderd antwoord uit de cache wordt teruggegeven. In named en dig is de mogelijkheid om externe verificatie uit te voeren ingebouwd. TLS-certificaten<\/a>, wat kan worden gebruikt voor het implementeren van strikte of gezamenlijke authenticatie op basis van TLS (RFC 9103).
