OPENVPN 2.6.9 -- RELEASED 12 FEBRUARY 2024
The OpenVPN community project team is proud to release OpenVPN 2.6.9. This is a
bugfix release containing one security fix for the Windows installer.
For details see Changes.rst
Security fixes:
* Windows Installer: fix CVE-2023-7235 where installing to a non-default
directory could lead to a local privilege escalation. Reported by Will
Dormann.
New features:
* Add support for building with mbedTLS 3.x.x
* New option --force-tls-key-material-export to only accept clients that can do
TLS keying material export to generate session keys (mostly an internal
option to better deal with TLS 1.0 PRF failures).
* Windows: bump vcpkg-ports/pkcs11-helper to 1.30
* Log incoming SSL alerts in easier to understand form and move logging
from --verb 8 to --verb 3.
* protocol_dump(): add support for printing --tls-crypt packets
User visible changes:
* License change is now complete, and all code has been re-licensed under the
new license (still GPLv2, but with new linking exception for Apache2 licensed
code). See COPYING for details.
> Code that could not be re-licensed has been removed or rewritten.
* The original code for the --tls-export-cert feature has been removed (due to
the re-licensing effort) and rewritten without looking at the original code.
Feature-compatibility has been tested by other developers, looking at both
old and new code and documentation, so there *should* not be a user-visible
change here.
* IPv6 route addition/deletion are now logged on the same level (3) as for
IPv4. Previously IPv6 was always logged at --verb 1.
* Better handling of TLS 1.0 PRF failures in the underlying SSL library (e.g.
on some FIPS builds) - this is now reported on startup, and clients before
2.6.0 that can not use TLS EKM to generate key material are rejected by the
server. Also, error messages are improved to see what exactly failed.
Notable bug fixes:
* FreeBSD: for servers with multiple clients, reporting of peer traffic
statistics would fail due to insufficient buffer space (Github: #487)
Windows MSI changes since 2.6.8:
* Security fix, see above
* Built against OpenSSL 3.2.0
* Included openvpn-gui updated to 11.47.0.0
* Windows GUI: always update tray icon on state change (Github: #669) (for
persistent connection profiles, "connecting" state would not show)

OPENVPN 2.6.8 -- RELEASED 17 NOVEMBER 2023
The OpenVPN community project team is proud to release OpenVPN 2.6.8. This is a
small bugfix release fixing a few regressions in 2.6.7 release.
For details see Changes.rst
User visible changes:
* Windows: print warning if pushed options require DHCP (e.g. DOMAIN-SEARCH)
and driver in use does not use DHCP (wintun, dco).
Bug fixes:
* SIGSEGV crash: Do not check key_state buffers that are in S_UNDEF state
(Github #449) - the new sanity check function introduced in 2.6.7 sometimes
tried to use a NULL pointer after an unsuccessful TLS handshake
* Windows: --dns option did not work when tap-windows6 driver was used, because
internal flag for "apply DNS option to DHCP server" wasn't set (Github #447)
* Windows: fix status/log file permissions, caused by regression after changing
to CMake build system (Github: #454, Trac: #1430)
* Windows: fix --chdir failures, also caused by error in CMake build system
(Github #448)
Windows MSI changes since 2.6.7:
* Included openvpn-gui updated to 11.46.0.0

OPENVPN 2.6.7 -- RELEASED 9 NOVEMBER 2023
The OpenVPN community project team is proud to release OpenVPN 2.6.7. This is a
bugfix release containing security fixes.
For details see Changes.rst
Security Fixes:
* CVE-2023-46850 OpenVPN versions between 2.6.0 and 2.6.6 incorrectly use a
send buffer after it has been free()d in some circumstances, causing some
free()d memory to be sent to the peer. All configurations using TLS (e.g. not
using --secret) are affected by this issue. (found while tracking down
CVE-2023-46849 / Github #400, #417)
* CVE-2023-46849 OpenVPN versions between 2.6.0 and 2.6.6 incorrectly
restore --fragment configuration in some circumstances, leading to a division
by zero when --fragment is used. On platforms where division by zero is
fatal, this will cause an OpenVPN crash. (Github #400, #417).
User visible changes:
* DCO: warn if DATA_V1 packets are sent by the other side - this a hard
incompatibility between a 2.6.x client connecting to a 2.4.0-2.4.4 server,
and the only fix is to use --disable-dco.
* Remove OpenSSL Engine method for loading a key. This had to be removed
because the original author did not agree to relicensing the code with the
new linking exception added. This was a somewhat obsolete feature anyway as
it only worked with OpenSSL 1.x, which is end-of-support.
* add warning if p2p NCP client connects to a p2mp server - this is a
combination that used to work without cipher negotiation (pre 2.6 on both
ends), but would fail in non-obvious ways with 2.6 to 2.6.
* add warning to --show-groups that not all supported groups are listed (this
is due the internal enumeration in OpenSSL being a bit weird, omitting X448
and X25519 curves).
* --dns: remove support for exclude-domains argument (this was a new 2.6
option, with no backend support implemented yet on any platform, and it turns
out that no platform supported it at all - so remove option again)
* warn user if INFO control message too long, do not forward to management
client (safeguard against protocol-violating server implementations)
New features:
* DCO-WIN: get and log driver version (for easier debugging).
* print "peer temporary key details" in TLS handshake
* log OpenSSL errors on failure to set certificate, for example if the
algorithms used are in acceptable to OpenSSL (misleading message would be
printed in cryptoapi / pkcs11 scenarios)
* add CMake build system for MinGW and MSVC builds
* remove old MSVC build system
* improve cmocka unit test building for Windows
Windows MSI changes since 2.6.6:
* Included openvpn-gui updated to 11.45.0.0
* Add clarity for error on missing management parameter. See GH #657
* Improve "OpenVPN GUI" tooltip handling See GH #649
* MSIs now use OpenSSL 3.1.4

OPENVPN 2.6.6 -- RELEASED 15 AUGUST 2023
The OpenVPN community project team is proud to release OpenVPN 2.6.6. This is a
small bugfix release.
For details see Changes.rst
User visible changes:
* OCC exit messages are now logged more visibly See GH #391.
* OpenSSL error messages are now logged with more details (for example, when
loading a provider fails, which .so was tried, and why did it fail) See GH
#361.
* print a more user-friendly message when tls-crypt-v2 client auth fails
* packaging now includes all documentation in the source tarball
New features:
* set WINS server via interactive service - this adds support for "dhcp-option
WINS 192.0.2.1" for DCO + wintun interfaces where no DHCP server is used. See
GH #373.
Windows MSI changes since 2.6.5:

OPENVPN 2.6.5 -- RELEASED 13 JUNE 2023
The OpenVPN community project team is proud to release OpenVPN 2.6.5. This is a
small bugfix release.
For details see Changes.rst
User visible changes:
* tapctl (windows): generate driver-specific names (if using tapctl to create
additional tap/wintun/dco devices, and not using --name). See GH #337.
* interactive service (windows): do not force target desktop for openvpn.exe -
this has no impact for normal use, but enables running of OpenVPN in a
scripted way when no user is logged on (for example, via task scheduler). See
GH openvpn-gui#626

OPENVPN 2.6.4 -- RELEASED 11 MAY 2023
The OpenVPN community project team is proud to release OpenVPN 2.6.4. This is a
small bugfix release.
For details see Changes.rst
Note:
* License amendment: all new commits fall under a modified license that
explicitly permits linking with Apache2 libraries (mbedTLS, OpenSSL) - see
COPYING for details. Existing code will fall under the new license as soon as
all contributors have agreed to the change - work ongoing.
Feature changes:
* DCO: support kernel-triggered key rotation (avoid IV reuse after
232 packets). This is the userland side, accepting a message from kernel, and
initiating a TLS renegotiation. As of 2.6.4 release, only implemented in
FreeBSD kernel.
Windows MSI changes since 2.6.3:
* Rebuilt included tap-windows driver with the correct version of the old
Windows 7 driver, removing a warning about unsigned driver on Windows 7
installation. See GH openvpn-build#365.

OPENVPN 2.6.3 -- RELEASED 13 APRIL 2023
The OpenVPN community project team is proud to release OpenVPN 2.6.3. This is a
small bugfix release.
For details see Changes.rst
Feature changes:
* Windows: support setting DNS domain in configurations without GUI and DHCP
(typically wintun or windco drivers), see GH openvpn#306.
Windows MSI changes since 2.6.2:
* Several Windows-specific issues fixed:
* ensure interactive service stays enabled after silent reinstall, see GH
openvpn-build#348, openvpn-build#349 and openvpn-build#351
* repair querying install path info for easyrsa-start.bat on some Windows
language versions, see GH openvpn-build#352.
* MSIs are now built against OpenSSL 3.1.0.
* Update included openvpn-gui to 11.41.0.0
* This update removes the ability to change the password of a private key
from the GUI. This was a niche feature which caused a direct dependency of
GUI on OpenSSL. Use openssl.exe directly if you need to edit a private key.
Note: Windows MSI was updated to I003 on April 26th. Changes in I003:
* The GPG subkey for creating the .asc files for the downloads has been
updated. You might need to re-download or update the GPG key if verifying the
signatures.
* Fix the encoding of some documentation/sample files included in the
installer. See GH openvpn-build#358
* Update include tap-windows6 driver to 9.25.0
* Fixes a problem with sending small non-IP packets (e.g. PPPoE) over the VPN
connection. See GH tap-windows6#158
* Note: The new driver is only used on Windows 10 and newer. We can't rebuild
drivers for Windows 7/8 since Microsoft doesn't support the signing
mechanism anymore. We include the previous driver version to still allow
installation on Windows 7/8.
* Update included openvpn-gui to 11.42.0.0
* Fixes a problem with passphrase prompt was sometimes not displayed. See GH
openvpn-gui#619
* Adds "Password Reveal" feature which allows you to see passwords while
entering them.

OPENVPN 2.6.2 -- RELEASED 24 MARCH 2023
The OpenVPN community project team is proud to release OpenVPN 2.6.2. This is
mostly a bugfix release with some improvements.
For details see Changes.rst
Feature changes:
* implement byte counter statistics for DCO Linux (p2mp server and client)
* implement byte counter statistics for DCO Windows (client only)
* --dns server <n> address ... now permits up to 8 v4 or v6 addresses
Important note for Linux DCO users:
* New control packets flow for data channel offloading on Linux: 2.6.2+ changes
the way OpenVPN control packets are handled on Linux when DCO is active,
fixing the lockups observed with 2.6.0/2.6.1 under high client
connect/disconnect activity. This is an INCOMPATIBLE change and therefore an
ovpn-dco kernel module older than v0.2.20230323 (commit ID 726fdfe0fa21) will
not work anymore and must be upgraded. The kernel module was renamed to
"ovpn-dco-v2.ko" in order to highlight this change and ensure that users and
userspace software could easily understand which version is loaded.
Attempting to use the old ovpn-dco with 2.6.2+ will lead to disabling DCO at
runtime.

OPENVPN 2.6.1 -- RELEASED 8 MARCH 2023
The OpenVPN community project team is proud to release OpenVPN 2.6.1. This is
mostly a bugfix release with some improvements.
For details see Changes.rst
Feature changes:
* Dynamic TLS Crypt: When both peers are OpenVPN 2.6.1+, OpenVPN will
dynamically create a tls-crypt key that is used for renegotiation. This
ensure that only the previously authenticated peer can do trigger
renegotiation and complete renegotiations.
* CryptoAPI (Windows): support issuer name as a selector. Certificate selection
string can now specify a partial issuer name string as
"--cryptoapicert ISSUER:<string>" where <string> is matched as a substring of
the issuer (CA) name in the certificate.
Note: configure now enables DCO build by default on FreeBSD and Linux. On Linux
this brings in a new default dependency for libnl-genl (for Linux distributions
that are too old to have a suitable version of the library, use "configure
--disable-dco")
Windows MSI changes since 2.6.1:

OPENVPN 2.6.0 -- RELEASED 25 JANUARY 2023
The OpenVPN community project team is proud to release OpenVPN 2.6.0. This is a
new stable release with some major new features.
For details see: Changes.rst
The Changes document also contains a section with workarounds for common
problems encountered when using OpenVPN with OpenSSL 3.
New features and improvements in 2.6.0 compared to 2.5.8:
* Data Channel Offload (DCO) kernel acceleration support for Windows, Linux,
and FreeBSD.
* OpenSSL 3 support.
* Improved handling of tunnel MTU, including support for pushable MTU.
* Outdated cryptographic algorithms disabled by default, but there are options
to override if necessary.
* Reworked TLS handshake, making OpenVPN immune to replay-packet state
exhaustion attacks.
* Added --peer-fingerprint mode for a more simplistic certificate setup and
verification.
* Added Pre-Logon Access Provider support to OpenVPN GUI for Windows.
* Improved protocol negotiation, leading to faster connection setup.
* Included openvpn-gui updated to 11.37.0.0. See CHANGES.rst.
* Updated easy-rsa3 bundled with the installer on Windows.
* Various bug fixes.

For details see Changes.rst
However, there were several enhancements of the Windows GUI component:
* OpenVPN 3 support -- the GUI can also work as a user interface for the
OpenVPN 3 client.
* pkcs11-id-management -- the GUI can list available pkcs11-ids and allows the
user to select one.
* Persistent connections -- the GUI lists connections started at boot by the
automatic service and lets the user control them. Interactive inputs such as
username/password with such connections are possible.

OPENVPN 2.5.4 -- RELEASED 5 OCT, 2021
The OpenVPN community project team is proud to release OpenVPN 2.5.4. This
release include a number of fixes and small improvements. One of the fixes is to
password prompting on windows console when stderr redirection is in use - this
breaks 2.5.x on Win11/ARM, and might also break on Win11/amd64. Windows
executable and libraries are now built natively on Windows using MSVC, not
cross-compiled on Linux as with earlier 2.5 releases. Windows installers include
updated OpenSSL and new OpenVPN GUI. The latter includes several improvements,
the most important of which is the ability to import profiles from URLs where
available. Installer version I602 fixes loading of pkcs11 files on Windows.
Installer version I603 fixes a bug in the version number as seen by Windows (was
2.5..4, not 2.5.4). Installer I604 fixes some small Windows issues.

IMPORTANT NOTICES
BF-CBC CIPHER IS NO LONGER THE DEFAULT
Cipher handling for the data channel cipher has been significantly changed
between OpenVPN 2.3/2.4 and v2.5, most notably there are no "default cipher
BF-CBC" anymore because it is no longer considered a reasonable default. BF-CBC
is still available, but it needs to be explicitly configured now.
For connections between OpenVPN 2.4 and v2.5 clients and servers, both ends will
be able to negotiate a better cipher than BF-CBC. By default they will select
one of the AES-GCM ciphers, but this can be influenced using the --data-ciphers
setting.
Connections between OpenVPN 2.3 and v2.5 that have no --cipher setting in the
config (= defaulting to BF-CBC and not being negotiation-capable) must be
updated. Unless BF-CBC is included in --data-ciphers or there is a "--cipher
BF-CBC" in the OpenVPN 2.5 config, a v2.5 client or server will refuse to talk
to a v2.3 server or client, because it has no common data channel cipher and
negotiating a cipher is not possible. Generally, we recommend upgrading such
setups to OpenVPN 2.4 or v2.5. If upgrading is not possible we recommend adding
data-ciphers AES-256-GCM:AES-128-GCM:AES-128-CBC (for v2.5+) or cipher
AES-128-CBC (v2.4.x and older) to the configuration of all clients and servers.
If you really need to use an unsupported OpenVPN 2.3 (or even older) release and
need to stay on BF-CBC (not recommended), the OpenVPN 2.5 based client will need
a config file change to re-enable BF-CBC. But be warned that BF-CBC and other
related weak ciphers will be removed in coming OpenVPN major releases.
For full details see the "Data channel cipher negotiation" section on the man
page.
CONNECTIVITY TO SOME VPN SERVICE PROVIDER MAY BREAK
Connecting with an OpenVPN 2.5 client to at least one commercial VPN service
that
implemented their own cipher negotiation method that always reports back that it
is using BF-CBC to the client is broken in v2.5. This has always caused warning
about mismatch ciphers. We have been in contact with some service providers and
they are looking into it. This is not something the OpenVPN community can fix.
If your commercial VPN does not work with a v2.5 client, complain to the VPN
service provider.
More details on these new features as well as a list of deprecated features and
user-visible changes are available in Changes.rst.

OPENVPN 2.5.2 -- RELEASED 21 APRIL, 2021
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.

OPENVPN 2.4.11 -- RELEASED 21 APRIL, 2021
The OpenVPN community project team is proud to release OpenVPN 2.4.11. 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. This release also
includes other bug fixes and improvements. The I602 Windows installers fix a
possible security issue with OpenSSL config autoloading on Windows
(CVE-2021-3606). Updated OpenSSL and OpenVPN GUI are included in Windows
installers.

A summary of the changes is available in Changes.rst, and a full list of changes
is available here.
Please note that LibreSSL is not a supported crypto backend. We accept patches
and we do test on OpenBSD 6.0 which comes with LibreSSL, but if newer versions
of LibreSSL break API compatibility we do not take responsibility to fix that.
Also note that 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.
Please note that OpenVPN 2.4 installers will not work on Windows XP. The last
OpenVPN version that supports Windows XP is 2.3.18, which is downloadable as
32-bit and 64-bit versions.
If you find a bug in this release, please file a bug report to our Trac bug
tracker. In uncertain cases please contact our developers first, either using
the openvpn-devel mailinglist or the developer IRC channel (#openvpn-devel at
irc.libera.chat). For generic help take a look at our official documentation,
wiki, forums, openvpn-users mailing list and user IRC channel (#openvpn at
irc.libera.chat).
Important: you will need to use the correct installer for your operating system.
The Windows 10 installer works on Windows 10 and Windows Server 2016/2019. The
Windows 7 installer will work on Windows 7/8/8.1/Server 2012r2. This is because
of Microsoft's driver signing requirements are different for kernel-mode devices
drivers, which in our case affects OpenVPN's tap driver (tap-windows6).
OPENVPN 2.4.10 -- RELEASED 9 DECEMBER, 2020
This is primarily a maintenance release with bugfixes and small improvements.
Windows installers include the latest OpenSSL version (1.1.1i) which includes
security fixes.

OPENVPN 2.4.9 -- RELEASED 17 APRIL, 2020
This is primarily a maintenance release with bugfixes and improvements. This
release also fixes a security issue (CVE-2020-11810, trac #1272) which allows
disrupting service of a freshly connected client that has not yet not negotiated
session keys. The vulnerability cannot be used to inject or steal VPN traffic.
A summary of the changes is available in Changes.rst, and a full list of changes
is available here.
Please note that LibreSSL is not a supported crypto backend. We accept patches
and we do test on OpenBSD 6.0 which comes with LibreSSL, but if newer versions

to always move NSIS installers to a non-user-writeable location before running
them. We are moving to MSI installers in OpenVPN 2.5, but OpenVPN 2.4.x will
remain NSIS-only.
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. For full
details, see the changelog. The new OpenVPN GUI features are documented here.
Please note that OpenVPN 2.4 installers will not work on Windows XP. The last
OpenVPN version that supports Windows XP is 2.3.18, which is downloadable as

OPENVPN 2.4.7 -- RELEASED 21 FEBRUARY, 2019

the big things is enhanced TLS 1.3 support. A summary of the changes is
available in Changes.rst, and a full list of changes is available here.
Please note that LibreSSL is not a supported crypto backend. We accept patches

Important: you will need to use the correct installer for your operating system.
The Windows 10 installer will not work on Windows 7/8/8.1/Server 2012r2. This is
because Microsoft's driver signing requirements and tap-windows6. For the same
reason you need to use an older installer with Windows Server 2016. This older
installer has a local privilege escalation vulnerability issue which we cannot
resolve for Windows Server 2016 until tap-windows6 passes the HLK test suite on
that platform. In the meanwhile we recommend Windows Server 2016 users to avoid
installing OpenVPN/tap-windows6 driver on hosts where all users can't be
trusted. Users of Windows 7-10 and Server 2012r2 are recommended to update to
latest installers as soon as possible.

OPENVPN 2.4.6 -- RELEASED 24 APRIL, 2018
This is primarily a maintenance release with minor bugfixes and improvements,
and one security relevant fix for the Windows Interactive Service. Windows
installer includes updated OpenVPN GUI and OpenSSL. Installer I601 included
tap-windows6 driver 9.22.1 which had one security fix and dropped Windows Vista
support. However, in installer I602 we had to revert back to tap-windows 9.21.2
due to driver getting reject on freshly installed Windows 10 rev 1607 and later
when Secure Boot was enabled. The failure was due to the new, more strict driver
signing requirements. The 9.22.1 version of the driver is in the process of
getting approved and signed by Microsoft and will be bundled in an upcoming
Windows installer.
Please note that LibreSSL is not a supported crypto backend. We accept patches
and we do test on OpenBSD 6.0 which comes with LibreSSL, but if newer versions
of LibreSSL break API compatibility we do not take responsibility to fix that.
Also note that 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.
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
