Pubblicato<\/a><\/noindex> aggiornamenti correttivi per i rami stabili del server DNS BIND 9.14.4 e 9.11.9<\/a><\/noindex>, oltre alla versione sperimentale in sviluppo 9.15.2. Nei nuovi rilasci \u00e8 stata corretta una vulnerabilit\u00e0 (CVE-2019-6471) causata da una condizione di competizione che pu\u00f2 portare a una denial of service (terminazione del processo al verificarsi di un assert) quando viene bloccato un grande numero di pacchetti in ingresso.<\/p>\n

Inoltre, nella nuova versione 9.14.4 \u00e8 stata aggiunta la supporto per l'API GeoIP2 per connettersi al database di localizzazione per indirizzi IP fornito da
\nMaxMind (attivato tramite la build con l'opzione «—with-geoip2»). Per GeoIP2 il supporto per alcune ACL \u00e8 stato interrotto (ad esempio, il controllo in base ai parametri di velocit\u00e0 di rete, organizzazione e codice paese), precedentemente supportati per la vecchia API GeoIP, il cui supporto non \u00e8 pi\u00f9 fornito da MaxMind. Sono state inoltre aggiunte nuove metriche dnssec-sign e dnssec-refresh con i contatori del numero di firme DNSSEC create e aggiornate.<\/p>\n

Inoltre, si pu\u00f2 notare rilascio<\/a><\/noindex> Server DNS Knot 2.8.3, in cui \u00e8 stato aggiunto il file di configurazione per il certificato\/chiave per TLS in kdig, aumentata l'informativit\u00e0 delle registrazioni nei log per le firme offline-KSK e per il modulo RRL, ampliate le verifiche della configurazione DNSSEC.<\/p>\n

\u00c8 stato rilasciato anche l'aggiornamento Knot Resolver 4.1.0, che corregge due vulnerabilit\u00e0<\/a><\/noindex> (CVE-2019-10190, CVE-2019-10191): la possibilit\u00e0 di bypassare la verifica DNSSEC per le query di nomi non esistenti (NXDOMAIN) e la possibilit\u00e0 di tornare a uno stato non protetto DNSSEC per un dominio protetto tramite DNSSEC attraverso lo spoofing dei pacchetti.<\/p>\n
