- Update from 2.5.0 to 2.5.4
- Update rootfile
- Tested new version in vm testbed. Openvpn server successfully started.
Client connections working with 2.5.0 also successfully worked with 2.5.4
- Changelog
Overview of changes in 2.5.4
Bugfixes
- fix prompting for password on windows console if stderr redirection
is in use - this breaks 2.5.x on Win11/ARM, and might also break
on Win11/adm64 when released.
- fix setting MAC address on TAP adapters (--lladdr) to use sitnl
(was overlooked, and still used "ifconfig" calls)
- various improvements for man page building (rst2man/rst2html etc)
- minor bugfix with IN6_IS_ADDR_UNSPECIFIED() use (breaks build on
at least one platform strictly checking this)
- fix minor memory leak under certain conditions in add_route() and
add_route_ipv6()
User-visible Changes
- documentation improvements
- copyright updates where needed
- better error reporting when win32 console access fails
New features
- also build man page on Windows builds
Overview of changes in 2.5.3
Bugfixes
- CVE-2121-3606
see https://community.openvpn.net/openvpn/wiki/SecurityAnnouncements
OpenVPN windows builds could possibly load OpenSSL Config files from
world writeable locations, thus posing a security risk to OpenVPN.
As a fix, disable OpenSSL config loading completely on Windows.
- disable connect-retry backoff for p2p (--secret) instances
(Trac #1010, #1384)
- fix build with mbedtls w/o SSL renegotiation support
- Fix SIGSEGV (NULL deref) receiving push "echo" (Trac #1409)
- MSI installers: properly schedule reboot in the end of installation
- fix small memory leak in free_key_ctx for auth_token
User-visible Changes
- update copyright messages in files and --version output
New features
- add --auth-token-user option (for --auth-token deployments without
--auth-user-pass in client config)
- improve MSVC building for Windows
- official MSI installers will now contain arm64 drivers and binaries
(x86, amd64, arm64)
Overview of changes in 2.5.2
Bugfixes
- CVE-2020-15078
see https://community.openvpn.net/openvpn/wiki/SecurityAnnouncements
This bug allows - under very specific circumstances - to trick a
server using delayed authentication (plugin or management) into
returning a PUSH_REPLY before the AUTH_FAILED message, which can
possibly be used to gather information about a VPN setup.
In combination with "--auth-gen-token" or an user-specific token auth
solution it can be possible to get access to a VPN with an
otherwise-invalid account.
- restore pushed "ping" settings correctly on a SIGUSR1 restart
- avoid generating unecessary mbed debug messages - this is actually
a workaround for an mbedTLS 2.25 bug when using Curve25519 and Curve448
ED curves - mbedTLS crashes on preparing debug infos that we do not
actually need unless running with "--verb 8"
- do not print inlined (<dh>...</dh>) Diffie Hellman parameters to log file
- fix Linux/SITNL default route lookup in case of multiple routing tables
with more than one default route present (always use "main table" for now)
- Fix CRL file handling in combination with chroot
User-visible Changes
- OpenVPN will now refuse to start if CRL file is not present at startup
time. At "reload time" absense of the CRL file is still OK (and the
in memory copy is used) but at startup it is now considered an error.
New features
- printing of the TLS ciphers negotiated has been extended, especially
displaying TLS 1.3 and EC certificates more correctly.
Overview of changes in 2.5.1
New features
- "echo msg" support, to enable the server to pushed messages that are
then displayed by the client-side GUI. See doc/gui-notes.txt and
doc/management-notes.txt.
Supported by the Windows GUI shipped in 2.5.1, not yet supported by
Tunnelblick and the Android GUI.
User-visible Changes
- make OPENVPN_PLUGIN_ENABLE_PF plugin failures FATAL - if a plugin offers
to set the "openvpn packet filter", and returns a failure when requested
to, OpenVPN 2.5.0 would crash trying to clean up not-yet-initialized
structure members. Since PF is going away in 2.6.0, this is just turning
the crash into a well-defined program abort, and no further effort has
been spent in rewriting the PF plugin error handling (see trac #1377).
Documentation
- rework sample-plugins/defer/simple.c - this is an extensive rewrite
of the plugin to bring code quality to acceptable standards and add
documentation on the various plugin API aspects. Since it's just
example code, filed under "Documentation", not under "Bugfix".
- various man page improvements.
- clarify ``--block-ipv6`` intent and direction
Bugfixes
- fix installation of openvpn.8 manpage on systems without docutils.
- Windows: fix DNS search list setup for domains with "-" chars.
- Fix tls-auth mismatch OCC message when tls-cryptv2 is used.
- Windows: Skip DHCP renew with Wintun adapter (Wintun does not support
DHCP, so this was just causing an - harmless - error and needless delay).
- Windows: Remove 1 second delay before running netsh - speeds up
interface init for wintun setups not using the interactive service.
- Windows: Fix too early argv freeing when registering DNS - this would
cause a client side crash on Windows if ``register-dns`` is used,
and the interactive service is not used.
- Android: Zero initialise msghdr prior to calling sendmesg.
- Fix line number reporting on config file errors after <inline> segments
(see Trac #1325).
- Fix port-share option with TLS-Crypt v2.
- tls-crypt-v2: also preload tls-crypt-v2 keys (if --persist-key), otherwise
dropping privs on the server would fail.
- tls-crypt-v2: fix server memory leak (about 600 bytes per connecting
client with tls-crypt-v2)
- rework handling of server-pushed ``--auth-token`` in combination with
``--auth-nocache`` on reconnection / TLS renegotiation events. This
used to "forget" to update new incoming token after a reconnection event
(leading to failure to reauth some time later) and now works in all
tested cases.

Most of these files still used old dates and/or domain names for contact
mail addresses. This is now replaced by an up-to-date copyright line.
Just some housekeeping... :-)

Update script for OpenVPNs CRL cause OpenVPN refactors the CRL handling since v.2.4.0 .
Script checks the next update field from the CRL and executes an update before it expires.
Script is placed under fcron.daily for daily checks.

The tls-remote directive is deprecated and will be removed with
OpenVPN version 2.4 . Added instead --verify-x509-name HOST name
into ovpnmain.cgi.

Besides an error in the update.sh file, openvpn now uses a lease file, to
to be able to "remember" dynamic ips not just for runtime but beyond reboots
or restarts of openvpn.
Also modified rootfiles and cgi as well as lfs.
