Publi\u00e9<\/a><\/noindex> Mises \u00e0 jour correctives des branches stables du serveur DNS BIND 9.14.4 et 9.11.9<\/a><\/noindex>, ainsi que la branche exp\u00e9rimentale 9.15.2 en cours de d\u00e9veloppement. Les nouvelles versions corrigent une vuln\u00e9rabilit\u00e9 (CVE-2019-6471) caus\u00e9e par une condition de course pouvant entra\u00eener un d\u00e9ni de service (arr\u00eat du processus lors de l'activation de l'assert) en bloquant un grand nombre de paquets entrants.<\/p>\n

De plus, la nouvelle version 9.14.4 ajoute la prise en charge de l'API GeoIP2 pour connecter la base de donn\u00e9es de localisation par adresse IP de l'entreprise
\nMaxMind (activ\u00e9 via le module avec l'option «—with-geoip2»). La prise en charge de certaines ACL pour GeoIP2 a \u00e9t\u00e9 interrompue (par exemple, la v\u00e9rification selon les param\u00e8tres de vitesse r\u00e9seau, d'organisation et de code pays), qui \u00e9taient auparavant prises en charge par l'ancienne API GeoIP, dont l'assistance n'est plus fournie par MaxMind. De nouvelles m\u00e9triques dnssec-sign et dnssec-refresh ont \u00e9galement \u00e9t\u00e9 ajout\u00e9es avec des compteurs du nombre de signatures DNSSEC g\u00e9n\u00e9r\u00e9es et mises \u00e0 jour.<\/p>\n

Il convient \u00e9galement de noter version<\/a><\/noindex> Serveurs DNS Knot 2.8.3, dans lequel un fichier de configuration de certificat\/cl\u00e9 pour TLS a \u00e9t\u00e9 ajout\u00e9 dans kdig, la lisibilit\u00e9 des enregistrements de journal a \u00e9t\u00e9 am\u00e9lior\u00e9e pour les signatures offline-KSK et le module RRL, et les v\u00e9rifications de configuration DNSSEC ont \u00e9t\u00e9 \u00e9tendues.<\/p>\n

Une mise \u00e0 jour de Knot Resolver 4.1.0 a \u00e9galement \u00e9t\u00e9 publi\u00e9e, dans laquelle les probl\u00e8mes suivants ont \u00e9t\u00e9 corrig\u00e9s deux vuln\u00e9rabilit\u00e9s<\/a><\/noindex> (CVE-2019-10190, CVE-2019-10191) : possibilit\u00e9 de contourner la v\u00e9rification DNSSEC pour les requ\u00eates de noms absents (NXDOMAIN) et possibilit\u00e9 de r\u00e9trograder un domaine prot\u00e9g\u00e9 par DNSSEC \u00e0 un \u00e9tat non prot\u00e9g\u00e9 par DNSSEC via le spoofing de paquets.<\/p>\n
