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.
