Przygotowano poprawki dla OpenVPN 2.5.6 i 2.4.12, pakietu do tworzenia wirtualnych sieci prywatnych, kt\u00f3ry umo\u017cliwia zorganizowanie szyfrowanego po\u0142\u0105czenia pomi\u0119dzy dwoma klientami lub zapewnienie dzia\u0142ania scentralizowanego serwera VPN dla jednoczesnej pracy wielu klient\u00f3w. Kod OpenVPN jest rozpowszechniany na licencji GPLv2, gotowe pakiety binarne s\u0105 tworzone dla Debian, Ubuntu, CentOS, RHEL i Windows. <\/p>\n

Problem wyst\u0119puje, gdy kilka wtyczek wysy\u0142a op\u00f3\u017anione odpowiedzi uwierzytelniaj\u0105ce, co pozwala u\u017cytkownikowi zewn\u0119trznemu uzyska\u0107 dost\u0119p na podstawie niekompletnych danych logowania.

Na platformie Linux usprawniono dzia\u0142anie opcji «—mtu-disc maybe|yes». Usuni\u0119to wyciek pami\u0119ci w procedurach dodawania tras.
