Korrigerande utg\u00e5vor av OpenVPN 2.5.6 och 2.4.12 har f\u00f6rberetts, paketet f\u00f6r att skapa virtuella privata n\u00e4tverk som m\u00f6jligg\u00f6r krypterad kommunikation mellan tv\u00e5 klientmaskiner eller en centralt hanterad VPN-server f\u00f6r samtidiga klienter. Koden f\u00f6r OpenVPN distribueras under GPLv2-licensen, f\u00e4rdiga bin\u00e4rpaket skapas f\u00f6r Debian, Ubuntu, CentOS, RHEL och Windows. <\/p>\n

I de nya versionerna har en s\u00e5rbarhet \u00e5tg\u00e4rdats som potentiellt kan kringg\u00e5 autentisering genom att manipulera externa plugins som st\u00f6der l\u00e4get f\u00f6r uppskjuten autentisering (deferred_auth). Problemet uppst\u00e5r n\u00e4r flera plugins skickar uppskjutna autentiseringssvar, vilket g\u00f6r att en extern anv\u00e4ndare kan f\u00e5 tillg\u00e5ng baserat p\u00e5 ofullst\u00e4ndiga autentiseringsuppgifter. Fr\u00e5n och med utg\u00e5vorna av OpenVPN 2.5.6 och 2.4.12 kommer f\u00f6rs\u00f6k att anv\u00e4nda uppskjuten autentisering av flera plugins att leda till ett felmeddelande. <\/p>\n

Bland annat kan man n\u00e4mna inkluderingen av den nya pluginen sample-plugin\/defer\/multi-auth.c, som kan vara anv\u00e4ndbar f\u00f6r att organisera tester f\u00f6r samtidig anv\u00e4ndning av olika autentiseringsplugins, f\u00f6r att i framtiden undvika s\u00e5rbarheter som den som diskuterades ovan. P\u00e5 plattformen Linux har funktionen «—mtu-disc maybe|yes» f\u00e5tt en smidig funktionalitet. En minnesl\u00e4cka i procedurerna f\u00f6r att l\u00e4gga till rutter har \u00e5tg\u00e4rdats.
