Objavljene so popravljalne posodobitve stabilnih razli\u010dic DNS stre\u017enika BIND 9.16.28 in 9.18.3 ter nova izdaja eksperimentalne razli\u010dice 9.19.1. V razli\u010dicah 9.18.3 in 9.19.1 je bila odpravita ranljivost (CVE-2022-1183) v implementaciji mehanizma DNS-over-HTTPS, ki je podprt od razli\u010dice 9.18. Ranljivost povzro\u010di nenadno prekinitev procesa named v primeru, da se TLS povezava na obdelovalnik, temelje\u010d na protokolu HTTP, prezgodaj prekine. Te\u017eava vpliva le servere<\/a>, na stre\u017enike, ki obravnavajo DNS over HTTPS (DoH). Stre\u017eniki, ki sprejemajo poizvedbe preko DNS over TLS (DoT) in ne uporabljajo DoH, niso podvr\u017eeni te\u017eavi. <\/p>\n

V izdanju 9.18.3 so bili dodani \u0161e nekateri funkcionalni izbolj\u0161ave. Dodana je podpora za drugo razli\u010dico kataloga con (\"Catalog Zones\"), dolo\u010deno v petem osnutku specifikacije IETF. Katalog con ponuja novo metodo vzdr\u017eevanja sekundarnih DNS stre\u017enikov, pri kateri se namesto dolo\u010danja lo\u010denih zapisov za vsako sekundarno cono na sekundarnem stre\u017eniku oblikuje prenos dolo\u010denega nabora sekundarnih con med primarnima in sekundarnima stre\u017enikom. To pomeni, da se ob nastavitvi prenosa kataloga, podobno kot pri prenosu lo\u010denih con, con, ki jih na primarnem stre\u017eniku ozna\u010dimo kot vklju\u010dene v katalog, avtomatsko ustvarijo na sekundarnem stre\u017eniku brez potrebe po urejanju konfiguracijskih datotek. <\/p>\n

V novi razli\u010dici je bila dodana tudi podpora za raz\u0161irjene kode napak \"Stale Answer\" in \"Stale NXDOMAIN Answer\", ki se izdata, ko zastarel odgovor vrne iz predpomnilnika. V named in dig je dodana mo\u017enost preverjanja zunanjih TLS-certifikatov<\/a>, kar se lahko uporablja za organizacijo stroge ali skupne avtentikacije na podlagi TLS (RFC 9103).
