Valmis on OpenVPN 2.5.6 ja 2.4.12 parandav v\u00e4ljalase, virtuaalsete privaatv\u00f5rkude pakett, mis v\u00f5imaldab luua kr\u00fcpteeritud \u00fchenduse kahe kliendimasina vahel v\u00f5i korraldada tsentraliseeritud VPN-serverit, mis toetab samal ajal mitme kliendi t\u00f6\u00f6tamist. OpenVPN kood on litsentseeritud GPLv2 all ning valmis binaarpaketid on saadaval Debian, Ubuntu, CentOS, RHEL ja Windowsi jaoks. <\/p>\n

Uutes versioonides on k\u00f5rvaldatud haavatavus, mis v\u00f5imaldab potentsiaalselt \u00fcletada autentimise kaudu manipuleerimise v\u00e4liste pistikprogrammidega, mis toetavad viivitatud autentimise re\u017eiimi (deferred_auth). Probleem ilmneb, kui mitu pistikprogrammi saadavad viivitatud autentimisvastuseid, mis v\u00f5imaldab v\u00e4lisel kasutajal saada ligip\u00e4\u00e4su mittet\u00e4ielike sisselogimistunnuste alusel. Alates OpenVPN 2.5.6 ja 2.4.12 versioonidest viivitatud autentimise kasutamine mitme pistikprogrammiga toob kaasa veateate. <\/p>\n

Teistest muudatustest v\u00f5ib m\u00e4rkida uue plugina sample-plugin\/defer\/multi-auth.c lisamist, mis v\u00f5ib olla kasulik erinevate autentimiste pluginate samaaegse kasutamise testimise korraldamiseks, et tulevikus v\u00e4ltida sarnaseid haavatavusi nagu \u00fclaltoodud. Linuxi platvormil on seadistatud valik «—mtu-disc maybe|yes». M\u00e4lu lekkimine marsruutide lisamise protseduurides on k\u00f5rvaldatud.
