Modifiche principali:  <\/p>\n<ul>\n<li class=\"l\"> Per utilizzare la versione portatile di OpenSSH, \u00e8 ora necessaria la supporto della crittografia basata su curve ellittiche (ECC \u2014 Elliptic Curve Cryptography) nella libreria libcrypto, inclusa la supporto della curva ellittica NISTP521. Nelle implementazioni di libcrypto dei progetti LibreSSL, OpenSSL, BoringSSL e AWS LC, tale supporto \u00e8 incluso per impostazione predefinita.\n<li class=\"l\"> Nell'utility ssh-keygen, durante il reset della password per le chiavi private dei token FIDO, \u00e8 stata implementata la possibilit\u00e0 di impostare i flag touch-required e verify-required, che richiedono la conferma da parte dell'utente.\n<li class=\"l\"> Nell'utility ssh \u00e8 stato modificato l'ordine di applicazione dei certificati durante l'autenticazione con chiavi pubbliche: ora vengono utilizzate per prime le chiavi FIDO, che non richiedono azioni da parte dell'utente, mentre in ultima analisi vengono utilizzate le chiavi che richiedono la verifica tramite PIN o biometria.\n<li class=\"l\"> Aggiunta il comando \u00abssh -Z user\u00bb, che visualizza le chiavi nell'ordine del loro utilizzo per l'autenticazione con chiavi pubbliche.\n<li class=\"l\"> Sono state risolte problematiche di sicurezza:\n<ul>\n<li class=\"l\"> \u00c8 stata corretta una gestione non corretta delle richieste di binding della sessione durante il blocco dell'SSH Agent, che portava a consentire operazioni remote, come l'aggiunta di token PKCS#11 e l'utilizzo di chiavi legate a server specifici, invece di rifiutare l'accesso.\n<li class=\"l\"> Nel client ssh \u00e8 stata eliminata una potenziale chiamata alla memoria dopo la sua liberazione (use-after-free), che si manifestava durante la multiplexazione delle connessioni SSH tramite un unico socket nel caso venisse aggiunto un nuovo port forwarding mentre il client attendeva ancora la <a class=\"wpil_keyword_link\" href=\"https:\/\/prohoster.info\/it\/server\/dts-los-angeles\/\" title=\"server\" data-wpil-keyword-link=\"linked\">server<\/a> risposta per l'apertura del precedente port forwarding.\n<li class=\"l\"> Nel sshd \u00e8 stata implementata correttamente l'applicazione delle restrizioni definite tramite il flag \u00abrestrict\u00bb nel file authorized_keys, per i tunnel reindirizzati.      <\/ul>\n<\/ul>\n<p>Fonte: <a rel=\"nofollow\"
