Autoritatea de certificare non-profit Let's Encrypt, controlat\u0103 de comunitate \u0219i care ofer\u0103 certificate gratuit oric\u0103rei persoane interesate, a anun\u021bat retragerea anticipat\u0103 a aproximativ dou\u0103 milioane de certificate TLS, ceea ce reprezint\u0103 aproximativ 1% din toate certificatele active emise de aceast\u0103 autoritate. Retragerea certificatelor a fost initiat\u0103 din cauza identific\u0103rii unor neconformit\u0103\u021bi fa\u021b\u0103 de specifica\u021biile standard \u00een codul utilizat de Let's Encrypt, legate de implementarea extensiei TLS-ALPN-01 (RFC 7301, Application-Layer Protocol Negotiation). Neconformitatea a fost cauzat\u0103 de lipsa unor verific\u0103ri efectuate \u00een timpul negocierii conexiunilor bazate pe extensia TLS ALPN, utilizat\u0103 \u00een HTTP\/2. Informa\u021bii detaliate despre incident vor fi publicate dup\u0103 finalizarea retragerii certificatelor problematice. <\/p>\n

Pe 26 ianuarie la ora 03:48 (MSK) problema a fost rezolvat\u0103, dar toate certificatele pentru care a fost utilizat\u0103 metoda de verificare TLS-ALPN-01 vor fi considerate invalide. Retragerea certificatelor va \u00eencepe pe 28 ianuarie la ora 19:00 (MSK). P\u00e2n\u0103 atunci, utilizatorii care folosesc metoda de verificare TLS-ALPN-01 sunt sf\u0103tui\u021bi s\u0103 \u00ee\u0219i actualizeze certificatele, altfel acestea vor fi considerate invalide anticipat. <\/p>\n

Notific\u0103rile corespunz\u0103toare privind necesitatea actualiz\u0103rii certificatelor au fost trimise pe email. Utilizatorii care utilizeaz\u0103 pentru ob\u021binerea certificatului instrumentele Certbot \u0219i dehydrated, cu set\u0103rile implicite, nu au fost afecta\u021bi de problem\u0103. Metoda TLS-ALPN-01 este suportat\u0103 \u00een pachetele Caddy, Traefik, apache mod_md \u0219i autocert. Verifica\u021bi corectitudinea certificatelor dvs. prin c\u0103utarea identificatorilor, numerelor de serie sau domenii<\/a> \u00een lista certificatelor problematice. <\/p>\n

Av\u00e2nd \u00een vedere c\u0103 modific\u0103rile afecteaz\u0103 comportamentul la verificarea prin metoda TLS-ALPN-01, pentru a continua func\u021bionarea, poate fi necesar\u0103 actualizarea clientului ACME sau modificarea set\u0103rilor (Caddy, bitnami\/bn-cert, autocert, apache mod_md, Traefik). Modific\u0103rile constau \u00een utilizarea versiunilor TLS de cel pu\u021bin 1.2 (clien\u021bii nu vor mai putea utiliza TLS 1.1) \u0219i \u00een \u00eencetarea suportului pentru OID 1.3.6.1.5.5.7.1.30.1, care identific\u0103 extensia \u00eenvechit\u0103 acmeIdentifier, suportat\u0103 doar \u00een variantele timpurii ale specifica\u021biei RFC 8737 (la generarea certificatului acum este permis doar OID 1.3.6.1.5.5.7.1.31, iar clien\u021bii care utilizeaz\u0103 OID 1.3.6.1.5.5.7.1.30.1 nu vor putea ob\u021bine certificat).
