In de updates is een kwetsbaarheid (CVE-2025-23419) verholpen die het mogelijk maakte om de controle van client TLS-certificaten te omzeilen.       <\/p>\n<p>De kwetsbaarheid wordt veroorzaakt door het ontbreken van adequate controles bij de verwerking van virtuele hosts die aan \u00e9\u00e9n IP-adres en poortnummer zijn gekoppeld, en die tijdens een HTTPS-aanroep worden geselecteerd op basis van de domeinnaam die is opgegeven met de TLS-uitbreiding SNI. In dergelijke configuraties kon een aanvaller de TLS-sessie hergebruiken in de context van een andere virtuele host om de authenticatie met een klant TLS-certificaat te omzeilen. Het probleem doet zich voor in configuraties die het hervatten van TLS-sessies ondersteunen via een \"TLS session ticket\" of die een TLS-sessiecache gebruiken in de instellingen. <a class=\"wpil_keyword_link\" href=\"https:\/\/prohoster.info\/nl\/server\/dts-los-angeles\/\"   title=\"de server\" data-wpil-keyword-link=\"linked\"  data-wpil-monitor-id=\"3903\">de server<\/a> standaard, waarin client TLS-certificaatauthenticatie wordt gebruikt. De kwetsbaarheid is aanwezig sinds de release van nginx 1.11.4 bij compilatie met OpenSSL en met inschakeling van het TLSv1.3-protocol.     <\/p>\n<p>Niet-beveiligingsgerelateerde wijzigingen:  <\/p>\n<ul>\n<li class=\"l\"> Er zijn mogelijkheden toegevoegd om het resourceverbruik te verminderen en de belasting op de CPU te verlagen bij het gebruik van TLS in configuraties met een groot aantal server- en location-blokken. De toegevoegde wijzigingen maken het mogelijk om in plaats van voor elk configuratieblok een aparte SSL-context (SSL_CTX in OpenSSL) aan te maken, de bestaande SSL-context uit het bovenliggende blok te gebruiken.\n<li class=\"l\"> Er zijn problemen opgelost met lange laadtijden van configuratiebestanden als gevolg van de herhaalde parsing van dezelfde set <a class=\"wpil_keyword_link\" href=\"https:\/\/prohoster.info\/nl\/ssl-sertifikat\/\"   title=\"TLS-certificaten\" data-wpil-keyword-link=\"linked\"  data-wpil-monitor-id=\"966\">TLS-certificaten<\/a>, sleutels en lijsten van certificeringsinstanties. De herstart van de configuratie is versneld door het hergebruik van ongewijzigde TLS-objecten, zoals certificaten, sleutels en CRL. Om het erven van objecten bij het bijwerken van de configuratie uit te schakelen, is de richtlijn \"ssl_object_cache_inheritable\" toegevoegd.\n<li class=\"l\"> Een cache is toegevoegd voor certificaten en sleutels die zijn geladen met behulp van variabelen in richtlijnen (bijvoorbeeld &#171;ssl_certificate      \/etc\/ssl\/$ssl_server_name.crt&#187;). Voor cachebeheer zijn de richtlijnen &#171;ssl_certificate_cache&#187;, &#171;proxy_ssl_certificate_cache&#187;, &#171;grpc_ssl_certificate_cache&#187; en &#171;uwsgi_ssl_certificate_cache&#187; toegevoegd. Via deze richtlijnen kan de maximale cachegrootte, de geldigheidsduur van records en de tijd voor het opschonen van ongebruikte records worden ingesteld. Bijvoorbeeld: &#171;ssl_certificate_cache max=1000 inactive=20s valid=1m;&#187;.\n<li class=\"l\"> De richtlijn &#171;keepalive_min_timeout&#187; is toegevoegd, die de timeout definieert waarin nginx geen keep-alive verbinding met de klant zal sluiten.\n<li class=\"l\"> Het probleem met de melding in de logs \"gzip filter failed to use preallocated memory\" is opgelost bij het bouwen met de zlib-ng bibliotheek.\n<li class=\"l\"> Het probleem met het bouwen van de libatomic bibliotheek is opgelost bij het gebruik van de bouwoptie \"--with-libatomic=DIR\".\n<li class=\"l\"> Een fout is verholpen die het onmogelijk maakte om verbinding te maken via het QUIC-protocol met gebruik van 0-RTT.\n<li class=\"l\"> Er is voorzien in het negeren van versieonderhandelingsverzoeken van QUIC die van clients komen.\n<li class=\"l\"> Problemen met de compilatie in Solaris 10 met de module ngx_http_v3_module zijn opgelost.\n<li class=\"l\"> Fouten in de implementatie van HTTP\/3 zijn gecorrigeerd.    <\/ul>\n<p>Bron: <a content=\"nofollow\" rel=\"nofollow\" href=\"https:\/\/www.opennet.ru\/opennews\/art.shtml?num=62679\">opennet.ru<\/a>
