Pripremljena su ispravna izdanja OpenVPN 2.5.6 i 2.4.12, paketa za kreiranje virtualnih privatnih mre\u017ea, koji omogu\u0107ava uspostavljanje \u0161ifrirane veze izme\u0111u dva klijentska ra\u010dunala ili rad centraliziranog VPN poslu\u017eitelja za simultani rad vi\u0161e klijenata. Kod OpenVPN-a distribuira se pod GPLv2 licencom, gotovi binarni paketi formiraju se za Debian, Ubuntu, CentOS, RHEL i Windows. <\/p>\n

U novim verzijama ispravljena je ranjivost koja potencijalno omogu\u0107ava zaobila\u017eenje autentifikacije manipulacijom s vanjskim pluginovima koji podr\u017eavaju na\u010din odlo\u017eene autentifikacije (deferred_auth). Problem se javlja kada nekoliko pluginova \u0161alje odlo\u017eene odgovore za autentifikaciju, \u0161to omogu\u0107ava vanjskom korisniku pristup temeljen na djelomi\u010dno ispravnim podacima za prijavu. Po\u010dev\u0161i od izdanja OpenVPN 2.5.6 i 2.4.12, poku\u0161aji kori\u0161tenja odlo\u017eene autentifikacije od strane vi\u0161e pluginova \u0107e rezultirati prikazivanjem gre\u0161ke. <\/p>\n

Od drugih promjena, mo\u017ee se istaknuti uklju\u010divanje novog dodatka sample-plugin\/defer\/multi-auth.c, koji mo\u017ee biti koristan za organizaciju testiranja paralelnog kori\u0161tenja razli\u010ditih dodataka za autentifikaciju, kako bi se ubudu\u0107e izbjegle ranjivosti poput one koja je ranije razmatrana. Na Linux platformi postavljena je opcija «—mtu-disc maybe|yes». Ispravljena je curenje memorije u procedurama dodavanja ruta.
