\u00dchenduse kontrollitud mittetulunduslik sertifitseerimiskeskus Let’s Encrypt, mis pakub tasuta sertifikaate k\u00f5igile soovijatele, kuulutas v\u00e4lja umbes kahe miljoni TLS-sertifikaadi ennetava tagasi kutsumise, mis moodustab umbes 1% k\u00f5igist selle sertifitseerimiskeskuse aktiivsetest sertifikaatidest. Sertifikaatide tagasikutsumine on algatatud seoses spetsifikatsiooni n\u00f5uetele mittevastavuse tuvastamisega Let’s Encrypt'i rakenduses TLS-ALPN-01 laienduse (RFC 7301, rakenduse taseme protokolli l\u00e4bir\u00e4\u00e4kimine) teostamisel. Mittevastavus oli seotud teatud kontrollide puudumisega, mis teostatakse TLS-ALPN laienduse, mida kasutatakse HTTP\/2, alusel \u00fchenduste l\u00e4bir\u00e4\u00e4kimise protsessis. \u00dcksikasjalik teave intsidentide kohta avaldatakse p\u00e4rast probleemseid sertifikaate tagasikutsumise l\u00f5ppu. <\/p>\n

26. jaanuaril kell 03:48 (MSK) probleem lahendati, kuid k\u00f5ik sertifikaadid, mille v\u00e4ljastamisel kasutati kontrollimeetodit TLS-ALPN-01, otsustati tunnistada kehtetuks. Sertifikaatide tagasiv\u00f5tmine algab 28. jaanuaril kell 19:00 (MSK). Kuni selle ajani soovitatakse kasutajatel, kes kasutavad TLS-ALPN-01 kontrollimeetodit, oma sertifikaate uuendada, vastasel juhul tunnistatakse need enne t\u00e4htaega kehtetuks. <\/p>\n

Asjakohased teated sertifikaatide uuendamise vajadusest on saadetud e-posti teel. Kasutajad, kes kasutavad sertifikaadi saamiseks Certbot'i ja dehydrated'i t\u00f6\u00f6riistu vaikeseadistustega, pole probleemist puudutatud. Meetod TLS-ALPN-01 on toetatud pakettides Caddy, Traefik, apache mod_md ja autocert. Oma sertifikaatide kehtivust saab kontrollida identifikaatorite, seerianumbrite v\u00f5i of domains<\/a> probleemsete sertifikaatide loendist. <\/p>\n

Kuna muudatused m\u00f5jutavad TLS-ALPN-01 meetodi kontrollimise k\u00e4itumist, v\u00f5ib ACME-klientide v\u00e4rskendamine v\u00f5i seadete muutmine (Caddy, bitnami\/bn-cert, autocert, apache mod_md, Traefik) osutuda vajalikuks. Muudatused seisnevad TLS-i versioonide kasutamises, mis ei ole madalamad kui 1.2 (klientidel ei ole enam v\u00f5imalik kasutada TLS 1.1) ja tugi OID 1.3.6.1.5.5.7.1.30.1, mis tuvastab vananenud laienduse acmeIdentifier, mis on toetatud ainult RFC 8737 spetsifikatsiooni varajastes mustandites, l\u00f5petatakse (sertifikaadi koostamisel on n\u00fc\u00fcd lubatud ainult OID 1.3.6.1.5.5.7.1.31 ning kliendid, kes kasutavad OID 1.3.6.1.5.5.7.1.30.1, ei saa sertifikaati).
