[Openvpn-announce] OpenVPN 2.4.4 released (with security fixes)

[Samuli S. <sa...@op...>]

The OpenVPN community project team is proud to release OpenVPN 2.4.4. It
can be downloaded from here:

<http://openvpn.net/index.php/open-source/downloads.html>

This release includes a large number of small fixes and enhancements.
There is also an important security fix for legacy setups that may still
be using key-method 1:

<https://community.openvpn.net/openvpn/wiki/CVE-2017-12166>

As that option was deprecated 12 years ago we estimate that not many
production setups are affected in practice.

In addition Windows installers have been built with NSIS version that
has been patched against several NSIS installer code execution and
privilege escalation problems:

Based on our testing, though, older Windows versions such as Windows 7
might not benefit from these fixes. We thus strongly encourage you to
always move NSIS installers to a non-user-writeable location before
running them. Our long-term plan is to migrate to using MSI installers
instead.

Windows installer I601 includes updated OpenVPN GUI (11.9.0.0) and
easy-rsa (2.3.2). Note that OpenVPN's bin directory is no longer added
to system PATH. While most users will be unaffected by this change, you
should have a look at vars.bat.sample if you are migrating an old
easy-rsa CA to a new easy-rsa installation.

A summary of all included changes is available here:

A full list of changes is available here:

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.

OpenVPN GUI bundled with the Windows installer has a large number of new
features compared to the one bundled with OpenVPN 2.3. One of major
features is the ability to run OpenVPN GUI without administrator privileges.
