Overview of changes in 2.5.8
New features
allow running a default configuration with TLS libraries without BF-CBC (even if TLS cipher negotiation would not actually use BF-CBC, the long-term compatibility "default cipher BF-CBC" would trigger an error on such TLS libraries)
User-visible Changes
add git branch name + commit ID to OpenVPN version string on MSVC builds (windows)
Testing Enhancements
t_client.sh: if fping is found and fping6 is not, assume we have fping 4.0 and up, and call "fping -6" for IPv6 ping tests
t_client.sh: allow to force FAIL on prerequisite fails, so a CI environment will no longer "silently skip" t_client runs if fping (etc) can not be found, but will error out
Bugfixes
``--auth-nocache'' was not always correctly clearing username+password after a renegotiation
ensure that auth-token received from server is cleared if requested by the management interface ("forget password" or automatically via ``--management-forget-disconnect'')
in a setup without username+password, but with auth-token and auth-token-username pushed by the server, OpenVPN would start asking for username+password on token expiry. Fix.
using --auth-token together with --management-client-auth (on the server) would lead to TLS keys getting out of sync and client being disconnected. Fix.
management interface would sometimes get stuck if client and server try to write something simultaneously. Fix by allowing a limited level of recursion in virtual_output_callback()
fix management interface not returning ERROR:/SUCCESS: response on "signal SIGxxx" commands when in HOLD state
tls-crypt-v2: abort connection if client-key is too short
make man page agree with actual code on replay-window backtrag log message
remove useless empty line from CR_RESPONSE message

OpenVPN 2.5.6.
This is mostly a bugfix release including one security fix ("Disallow multiple deferred authentication plug-ins.", CVE: 2022-0547).
|
|
Overview of changes in 2.5.5
============================
User-visible Changes
--------------------
- SWEET32/64bit cipher deprecation change was postponed to 2.7
- Windows: use network address for emulated DHCP server as default
this enables use of a /30 subnet, which is needed when connecting
to OpenVPN Cloud.
- require EC support in windows builds
(this means it's no longer possible to build a Windows OpenVPN binary
with an OpenSSL lib without EC support)
New features
------------
- Windows build: use CFG and Spectre mitigations on MSVC builds
- bring back OpenSSL config loading to Windows builds.
OpenSSL config is loaded from %installdir%\SSL\openssl.cfg
(typically: c:\program files\openvpn\SSL\openssl.cfg) if it exists.
This is important for some hardware tokens which need special
OpenSSL config for correct operation.
Bugfixes
--------
- Windows build: enable EKM
- Windows build: improve various vcpkg related build issues
- Windows build: fix regression related to non-writeable status files
- Windows build: fix regression that broke OpenSSL EC support
- Windows build: fix "product version" display (2.5..4 -> 2.5.4)
- Windows build: fix regression preventing use of PKCS12 files
- improve "make check" to notice if "openvpn --show-cipher" crashes
- improve argv unit tests
- ensure unit tests work with mbedTLS builds without BF-CBC ciphers
- include "--push-remove" in the output of "openvpn --help"
- fix error in iptables syntax in example firewall.sh script
- fix "resolvconf -p" invocation in example "up" script
- fix "common_name" environment for script calls when
"--username-as-common-name" is in effect
Documentation
-------------
- move "push-peer-info" documentation from "server options" to "client"
(where it belongs)
- correct "foreign_option_{n}" typo in manpage
- update IRC information in CONTRIBUTING.rst (libera.chat)
- README.down-root: fix plugin module name

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

The OpenVPN community project team is proud to release OpenVPN 2.5.2. It fixes two related security vulnerabilities (CVE-2020-15078) which under very specific circumstances allow tricking 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 a user-specific token auth solution it can be possible to get access to a VPN with an otherwise-invalid account. OpenVPN 2.5.2 also includes other bug fixes and improvements. Updated OpenSSL and OpenVPN GUI are included in Windows installers.

Version 2.4.4
=============
This is primarily a maintenance release, with further improved OpenSSL 1.1
integration, several minor bug fixes and other minor improvements.
Bug fixes
---------
- Fix issues when a pushed cipher via the Negotiable Crypto Parameters (NCP) is
rejected by the remote side
- Ignore ``--keysize`` when NCP have resulted in a changed cipher.
- Configurations using ``--auth-nocache`` and the management interface to provide
user credentials (like NetworkManager on Linux) on client side with servers
implementing authentication tokens (for example, using ``--auth-gen-token``)
will now behave correctly and not query the user for an, to them, unknown
authentication token on renegotiations of the tunnel.
- Fix bug causing invalid or corrupt SOCKS port number when changing the
proxy via the management interface.
- The man page should now have proper escaping of hyphens/minus characters
and have seen some minor corrections.
User-visible Changes
--------------------
- Linux servers with systemd which uses the ``openvpn-server@.service`` unit
file for server configurations will now utilize the automatic restart feature
in systemd. If the OpenVPN server process dies unexpectedly, systemd will
ensure the OpenVPN configuration will be restarted without any user interaction.
Deprecated features
-------------------
- ``--no-replay`` is deprecated and will be removed in OpenVPN 2.5.
- ``--keysize`` is deprecated in OpenVPN 2.4 and will be removed in v2.6
Security
--------
- CVE-2017-12166: Fix bounds check for configurations using ``--key-method 1``.
Before this fix, it could allow an attacker to send a malformed packet to
trigger a stack overflow. This is considered to be a low risk issue, as
``--key-method 2`` has been the default since OpenVPN 2.0 (released on
2005-04-17). This option is already deprecated in v2.4 and will be
completely removed in v2.5.

Compared to OpenVPN 2.3 this is a major update with a large number of new features, improvements and fixes. Some of the major features are AEAD (GCM) cipher and Elliptic Curve DH key exchange support, improved IPv4/IPv6 dual stack support and more seamless connection migration when client's IP address changes (Peer-ID). Also, the new --tls-crypt feature can be used to increase users' connection privacy.
Compared to OpenVPN 2.4.1 there are several bugfixes and small enhancements. A summary of the changes is available in Changes.rst.
|
|
* fix redirect-gateway behaviour when an IPv4 default route does not exist
* Avoid a 1 byte overcopy in x509_get_subject (ssl_verify_openssl.c)
* Check for errors in the return value of GetModuleFileNameW()
* Fix gateway detection with OpenBSD routing domains

The most important change in this release is that TLS version negotiation is no longer used unless it's explicitly turned on in the configuration files, thus reverting back to the 2.3.2 behaviour as interoperability issues were encountered in 2.3.3. Other notable changes include addition of SSL library version reporting, fixing of SOCKSv5 authentication logic and making serial env exporting consistent between OpenSSL and PolarSSL. This release also contains a number of other bug fixes and small enhancements.

Bump openvpn-acct-wtmpx to add its licence and to take into account the
new location of plugin directory
Significant changes since 2.2.x:
* Full IPv6 support
* SSL layer modularised, enabling easier implementation for other SSL
libraries
* PolarSSL support as a drop-in replacement for OpenSSL
* New plug-in API providing direct certificate access, improved logging API
and easier to extend in the future
* Added 'dev_type' environment variable to scripts and plug-ins - which
is set to 'TUN' or 'TAP'
* New feature: --management-external-key - to provide access to the
encryption keys via the management interface
* New feature: --x509-track option, more fine grained access to X.509
fields in scripts and plug-ins
* New feature: --client-nat support
* New feature: --mark which can mark encrypted packets from the tunnel,
suitable for more advanced routing and firewalling
* New feature: --management-query-proxy - manage proxy settings via the
management interface (supercedes --http-proxy-fallback)
* New feature: --stale-routes-check, which cleans up the internal
routing table
* New feature: --x509-username-field, where other X.509v3 fields can be
used for the authentication instead of Common Name
* Improved client-kill management interface command
* Improved UTF-8 support - and added --compat-names to provide backwards
compatibility with older scripts/plug-ins
* Improved auth-pam with COMMONNAME support, passing the certificate's
common name in the PAM conversation
* More options can now be used inside <connection> blocks
* Completely new build system, enabling easier cross-compilation and
Windows builds
* Much of the code has been better documented
* Many documentation updates
* Plenty of bug fixes and other code clean-ups
