[Openvpn-users] OpenVPN 2.6.14 released

[Yuriy D. <yur...@op...>]

The OpenVPN community project team is proud to release OpenVPN 2.6.14.

This is a bugfix release containing one security fix.

Security fixes:

* CVE-2025-2704: fix possible ASSERT() on OpenVPN servers using --tls-crypt-v2 Security scope: OpenVPN servers
  between 2.6.1 and 2.6.13 using --tls-crypt-v2 can be made to abort with an ASSERT() message by sending a particular
  combination of authenticated and malformed packets. To trigger the bug, a valid tls-crypt-v2 client key is needed, or network
  observation of a handshake with a valid tls-crypt-v2 client key. No crypto integrity is violated, no data is leaked, and no remote
  code execution is possible. This bug does not affect OpenVPN clients. (Bug found by internal QA at OpenVPN Inc)

Bug fixes:

* Linux DCO: repair source IP selection for --multihome (Qingfang Deng)

Windows MSI changes since 2.6.13:

* Built against OpenSSL 3.4.1
* Included openvpn-gui updated to 11.52.0.0

    * Use correct %TEMP% directory for debug log file.
    * Disable config in menu listing if its ovpn file becomes inaccessible (github openvpn-gui#729)

common problems encountered when using OpenVPN with OpenSSL 3)
