Sono state pubblicate le aggiornamenti correttivi per le versioni stabili del server DNS BIND 9.16.28 e 9.18.3, insieme a una nuova versione della branch sperimentale 9.19.1. Nelle versioni 9.18.3 e 9.19.1 \u00e8 stata corretta una vulnerabilit\u00e0 (CVE-2022-1183) nell'implementazione del meccanismo DNS-over-HTTPS, supportato a partire dalla branch 9.18. La vulnerabilit\u00e0 provoca il crash del processo named nel caso in cui la connessione TLS con il server HTTP venga interrotta prematuramente. La problematica riguarda solo server<\/a>, i server che gestiscono le richieste DNS over HTTPS (DoH). I server che accettano richieste tramite DNS over TLS (DoT) e non utilizzano DoH non sono vulnerabili alla problematica. <\/p>\n

Nella versione 9.18.3 sono stati inoltre aggiunti diversi miglioramenti funzionali. \u00c8 stata introdotta la supporto per la seconda versione del Catalogo delle Zone (\"Catalog Zones\"), definita nel quinto draft della specifica IETF. Il Catalogo delle Zone propone un nuovo metodo per mantenere i server DNS secondari, in cui, anzich\u00e9 definire sul server secondario singole voci per ogni zona secondaria, viene organizzato un trasferimento di un determinato set di zone secondarie tra i server primari e secondari. Vale a dire, impostando il trasferimento del catalogo analogamente al trasferimento di singole zone, le zone create sul server primario e contrassegnate come appartenenti al catalogo verranno automaticamente create sul server secondario senza necessit\u00e0 di modificare i file di configurazione. <\/p>\n

Nella nuova versione \u00e8 stata anche aggiunta la supporto per i codici di errore estesi \"Stale Answer\" e \"Stale NXDOMAIN Answer\", emessi quando una risposta obsoleta viene restituita dalla cache. In named e dig \u00e8 stata integrata la funzionalit\u00e0 di verifica esterna. certificati TLS.<\/a>, che pu\u00f2 essere utilizzata per organizzare un'autenticazione rigorosa o collaborativa basata su TLS (RFC 9103).
