Name of the Vulnerable Software and Affected Versions OpenVPN versions prior to 2.4.3 OpenVPN versions prior to 2.3.17

Recommendations For versions prior to 2.4.3, update to version 2.4.3 or later to resolve the issue. For versions prior to 2.3.17, update to version 2.3.17 or later to resolve the issue. As a temporary workaround, consider restricting access to authenticated remote users until a patch is applied.
