\u00dcksikisikutele tasuta sertifikaate pakkuv mittetulunduslik tunnistusasutus Let's Encrypt, mis tegutseb kogukonna kontrolli all, teatas, et kutsub tagasi umbes kaks miljonit TLS-sertifikaati, mis moodustab umbes 1% k\u00f5igist selle sertifikaadiasutuse aktiivsetest sertifikaatidest. Sertifikaatide tagasiv\u00f5tmine algatati spetsifikatsiooni n\u00f5uete rikkumise tuvastamise t\u00f5ttu Let's Encrypt'i koodis, mis rakendab TLS-ALPN-01 laiendust (RFC 7301, rakendusprotokollide l\u00e4bir\u00e4\u00e4kimine). Rikkumine oli seotud m\u00f5nede kontrollide puudumisega, mis teostatakse TLS-ALPN laiendust kasutavate \u00fchenduste l\u00e4bir\u00e4\u00e4kimiste k\u00e4igus, mida rakendatakse HTTP\/2 korral. \u00dcksikasjalik teave juhtumi kohta avaldatakse p\u00e4rast probleemsete sertifikaatide tagasiv\u00f5tmise l\u00f5petamist. <\/p>\n

26. jaanuaril kell 03:48 (MSK) probleem lahendati, kuid k\u00f5ik sertifikaadid, mille v\u00e4ljaandmisel kasutati verifitseerimismeetodit TLS-ALPN-01, otsustati tunnistada kehtetuks. Sertifikaatide t\u00fchistamine algab 28. jaanuaril kell 19:00 (MSK). Selle ajani soovitatakse kasutajatel, kes kasutavad tuvastamise meetodit TLS-ALPN-01, oma sertifikaate kiiresti uuendada, vastasel juhul tunnustatakse need ennetavalt kehtetuks. <\/p>\n

Asjakohased teated sertifikaatide uuendamise vajadusest on saadetud e-posti teel. Kasutajad, kes kasutavad sertifikaadi saamiseks t\u00f6\u00f6riistu Certbot ja dehydrated, ei puutunud vaikeseadete kasutamisel probleemiga kokku. Meetod TLS-ALPN-01 on toetatud pakettides Caddy, Traefik, apache mod_md ja autocert. Sertifikaatide kehtivust saab kontrollida ID-de, seerianumbrite v\u00f5i domeenide<\/a> probleemsete sertifikaatide loendis. <\/p>\n

Kuna muudatused m\u00f5jutavad TLS-ALPN-01 meetodil kontrollimise k\u00e4itumist, v\u00f5ib t\u00f6\u00f6 j\u00e4tkamiseks olla vajalik ACME-klientide uuendamine v\u00f5i seadete muutmine (Caddy, bitnami\/bn-cert, autocert, apache mod_md, Traefik). Muudatused h\u00f5lmavad TLS versioonide kasutamist mitte madalama kui 1.2 (kliendid ei saa enam kasutada TLS 1.1) ja OID 1.3.6.1.5.5.7.1.30.1, mis identifitseerib vananenud laienduse acmeIdentifier, toe l\u00f5petamist, mis oli toetatud ainult varastes RFC 8737 spetsifikatsiooni mustandites (sertifikaadi loomisel on n\u00fc\u00fcd lubatud ainult OID 1.3.6.1.5.5.7.1.31, ja kliendid, kes kasutavad OID 1.3.6.1.5.5.7.1.30.1, ei saa sertifikaati v\u00e4ljastada).
