Updated OpenSSL and OpenVPN GUI are included in Windows installers. The I602 Windows installers fix a possible security issue with OpenSSL config autoloading on Windows (CVE-2021-3606). This release also includes other bug fixes and improvements. 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. The OpenVPN community project team is proud to release OpenVPN 2.4.11. Installer I604 fixes some small Windows issues. Installer version I603 fixes a bug in the version number as seen by Windows (was 2.5.4, not 2.5.4). Installer version I602 fixes loading of pkcs11 files on Windows.
The latter includes several improvements, the most important of which is the ability to import profiles from URLs where available. Windows installers include updated OpenSSL and new OpenVPN GUI. Windows executable and libraries are now built natively on Windows using MSVC, not cross-compiled on Linux as with earlier 2.5 releases.
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. This release include a number of fixes and small improvements. The OpenVPN community project team is proud to release OpenVPN 2.5.4.
