Description
Frank Lichtenheld reports: [OpenVPN v2.6.13 ...] improve server-side handling of clients sending usernames or passwords longer than USER_PASS_LEN - this would not result in a crash, buffer overflow or other security issues, but the server would then misparse incoming IV variables and produce misleading error messages.
