Ver\u00f6ffentlicht<\/a><\/noindex> Korrektur-Updates der stabilen DNS-Server-Zweige BIND 9.14.4 und 9.11.9<\/a><\/noindex>, sowie der sich in der Entwicklung befindenden experimentellen Version 9.15.2. In den neuen Ver\u00f6ffentlichungen wurde eine Schwachstelle (CVE-2019-6471) beseitigt, die durch einen Race-Condition verursacht wird und zu einem Dienstausfall (Prozessende bei Ausf\u00fchrung von assert) f\u00fchren kann, wenn eine gro\u00dfe Anzahl an eingehenden Paketen blockiert wird.<\/p>\n

Dar\u00fcber hinaus wurde in der neuen Version 9.14.4 die Unterst\u00fctzung f\u00fcr die GeoIP2-API hinzugef\u00fcgt, um eine Standortdatenbank anhand von IP-Adressen des Unternehmens
\nMaxMind (wird \u00fcber die Option «—with-geoip2» aktiviert). F\u00fcr GeoIP2 wurde die Unterst\u00fctzung f\u00fcr bestimmte ACL eingestellt (zum Beispiel die \u00dcberpr\u00fcfung nach Netzwerkgeschwindigkeit, Organisation und L\u00e4ndercode), die zuvor f\u00fcr die alte GeoIP-API unterst\u00fctzt wurden, die von MaxMind nicht mehr gewartet wird. Au\u00dferdem wurden neue Metriken dnssec-sign und dnssec-refresh mit Z\u00e4hlern f\u00fcr die Anzahl der erstellten und aktualisierten DNSSEC-Signaturen hinzugef\u00fcgt.<\/p>\n

speziellen Distribution Ver\u00f6ffentlichung<\/a><\/noindex> DNS-Server Knot 2.8.3, in dem eine Konfigurationsdatei f\u00fcr das Zertifikat\/den Schl\u00fcssel f\u00fcr TLS in kdig hinzugef\u00fcgt wurde, die Informationsdichte in den Protokolldateien f\u00fcr offline-KSK-Signaturen und das RRL-Modul wurde erh\u00f6ht, und die \u00dcberpr\u00fcfungen der DNSSEC-Konfiguration wurden erweitert.<\/p>\n

Es wurde auch ein Update f\u00fcr Knot Resolver 4.1.0 ver\u00f6ffentlicht, das zwei Sicherheitsanf\u00e4lligkeiten<\/a><\/noindex> (CVE-2019-10190, CVE-2019-10191): die M\u00f6glichkeit, die DNSSEC-\u00dcberpr\u00fcfung f\u00fcr Anfragen an nicht vorhandene Namen (NXDOMAIN) zu umgehen, sowie die M\u00f6glichkeit, eine durch DNSSEC gesch\u00fctzte Domain durch Paket-Spoofing auf den Status einer ungesch\u00fctzten DNSSEC-Domain zur\u00fcckzusetzen.<\/p>\n
