[Openvpn-announce] OpenVPN 2.6.13 released

[Frank L. <fr...@li...>]

The OpenVPN community project team is proud to release OpenVPN 2.6.13.

This is a bugfix release.

Feature changes:

* on non-windows clients (MacOS, Linux, Unix) send "release" string from uname()
  call as IV_PLAT_VER to server - while highly OS specific this is still helpful
  to keep track of OS versions used on the client side (github ​#637)
* Windows: protect cached username, password and token in client memory (using
  the CryptProtectMemory() windows API)
* Windows: use new API to get dco-win driver version from driver (newly introduced
  non-exclusive control device) (github ​ovpn-dco-win#76)
* Linux: pass --timeout=0 argument to systemd-ask-password, to avoid default timeout
  of 90 seconds ("console prompting also has no timeout") (github ​#649) 

Security fixes:

* improve server-side handling of clients sending usernames or passwords longer than
  USER_PASS_LEN - this would not result in a crash, buffer overflow or other security
  issues, but the server would then misparse incoming IV variables and produce
  misleading error messages. 

Notable bug fixes:

* FreeBSD DCO: fix memory leaks in nvlist handling (github ​#636)
* purge proxy authentication credentials from memory after use
  (if --auth-nocache is in use) 

Windows MSI changes since 2.6.12:

* Built against OpenSSL 3.4.0
* Included openvpn-gui updated to 11.51.0.0
  * Higher resolution eye icons (github ​openvpn-gui#697)
  * Support for concatenating OTP with password
  * Optionally always prompt for OTP
  * Fix tooltip positioning when the taskbar is at top (github ​openvpn-gui#710) 

Debian/Ubuntu community packages are now available for Ubuntu 24.10 (oracular).
