  "description": "OpenVPN can be extended through the --plugin option, which provides possibilities to add specialized authentication, user accounting, packet filtering and related features. These plug-ins need to be written in C and provides a more low-level and information rich access to similar features as the various script-hooks.\r\n\r\nSecurity Fix(es):\r\n\r\nOpenVPN 2.1 until v2.4.12 and v2.5.6 may enable authentication bypass in external authentication plug-ins when more than one of them makes use of deferred authentication replies, which allows an external user to be granted access with only partially correct credentials.(CVE-2022-0547)",
