Am 26. Januar um 03:48 (MSK) wurde das Problem behoben, jedoch werden alle Zertifikate, f\u00fcr deren Ausstellung die Methode TLS-ALPN-01 verwendet wurde, als ung\u00fcltig anerkannt. Der Widerruf der Zertifikate beginnt am 28. Januar um 19:00 (MSK). Bis dahin wird allen Nutzern, die die Methode zur TLS-ALPN-01-\u00dcberpr\u00fcfung verwenden, geraten, ihre Zertifikate rechtzeitig zu aktualisieren, da sie sonst vorzeitig f\u00fcr ung\u00fcltig erkl\u00e4rt werden. <\/p>\n

Die entsprechenden Benachrichtigungen \u00fcber die Notwendigkeit der Aktualisierung der Zertifikate wurden per E-Mail versendet. Nutzer, die zur Zertifikatsbeschaffung die Werkzeuge Certbot und dehydrated verwenden, sind bei Verwendung der Standardeinstellungen von dem Problem nicht betroffen. Die Methode TLS-ALPN-01 wird in den Paketen Caddy, Traefik, apache mod_md und autocert unterst\u00fctzt. Die Richtigkeit ihrer Zertifikate k\u00f6nnen die Nutzer \u00fcberpr\u00fcfen, indem sie nach Identifikatoren, Seriennummern oder Dom\u00e4nen<\/a> in der Liste der betroffenen Zertifikate suchen. <\/p>\n

Da die \u00c4nderungen das Verhalten der TLS-ALPN-01-\u00dcberpr\u00fcfung betreffen, kann ein Update des ACME-Clients oder eine \u00c4nderung der Einstellungen (Caddy, bitnami\/bn-cert, autocert, apache mod_md, Traefik) erforderlich sein, um die Funktionalit\u00e4t fortzusetzen. Die \u00c4nderungen umfassen die Verwendung von TLS-Versionen, die mindestens 1.2 sind (Clients k\u00f6nnen nun TLS 1.1 nicht mehr verwenden) und die Einstellung der Unterst\u00fctzung f\u00fcr OID 1.3.6.1.5.5.7.1.30.1, die eine veraltete Erweiterung acmeIdentifier identifiziert, die nur in fr\u00fchen Entw\u00fcrfen der RFC 8737-Spezifikation unterst\u00fctzt wurde (bei der Erstellung von Zertifikaten ist nur noch OID 1.3.6.1.5.5.7.1.31 zul\u00e4ssig, und Clients, die OID 1.3.6.1.5.5.7.1.30.1 verwenden, k\u00f6nnen kein Zertifikat erhalten).
