Der er udgivet rettelser til OpenVPN 2.5.6 og 2.4.12, pakken til oprettelse af virtuelle private netv\u00e6rk, der muligg\u00f8r krypteret forbindelse mellem to klientmaskiner eller sikrer drift af en centraliseret VPN-server for samtidig betjening af flere klienter. OpenVPN-koden distribueres under GPLv2-licensen, og der findes f\u00e6rdige bin\u00e6re pakker til Debian, Ubuntu, CentOS, RHEL og Windows. <\/p>\n

I de nye versioner er en s\u00e5rbarhed rettet, som potentielt kunne tillade omg\u00e5else af autentificering via manipulation med eksterne plugins, der underst\u00f8tter deferred authentication-tilstand (deferred_auth). Problemet opst\u00e5r, n\u00e5r flere plugins sender udskudte autentificeringssvar, hvilket giver en ekstern bruger adgang baseret p\u00e5 ikke helt korrekte legitimationsoplysninger. Fra og med udgivelserne OpenVPN 2.5.6 og 2.4.12 vil fors\u00f8g p\u00e5 at bruge udskudt autentificering fra flere plugins f\u00f8re til en fejlmeddelelse. <\/p>\n

Af de andre \u00e6ndringer kan det n\u00e6vnes, at et nyt plugin sample-plugin\/defer\/multi-auth.c er blevet inkluderet, hvilket kan v\u00e6re nyttigt til at organisere testning af samtidig brug af forskellige autentificeringsplugins, for p\u00e5 den m\u00e5de at undg\u00e5 s\u00e5rbarheder, der ligner den, der blev diskuteret tidligere. P\u00e5 Linux-platformen er der etableret funktionalitet for indstillingen \u00ab\u2014mtu-disc maybe|yes\u00bb. En hukommelses l\u00e6kage i procedurer til tilf\u00f8jelse af ruter er blevet rettet.
