| OpenVPN from 2.6.0 through 2.6.10 in a server role accepts multiple exit notifications from authenticated clients which will extend the validity of a closing session | ||||
| CVE-2024-4877 | 2 Microsoft, Openvpn | 2 Windows, Openvpn | 2025-04-29 | 8.8 High |
| OpenVPN version 2.4.0 through 2.6.10 on Windows allows an external, lesser privileged process to create a named pipe which the OpenVPN GUI component would connect to allowing it to escalate its privileges | ||||
| CVE-2017-7522 | 1 Openvpn | 1 Openvpn | 2025-04-20 | N/A |
| OpenVPN versions before 2.4.3 and before 2.3.17 are vulnerable to denial-of-service by authenticated remote attacker via sending a certificate with an embedded NULL character. | ||||

| OpenVPN versions before 2.4.3 and before 2.3.17 are vulnerable to denial-of-service and/or possibly sensitive memory leak triggered by man-in-the-middle attacker. | ||||
| CVE-2017-7508 | 1 Openvpn | 1 Openvpn | 2025-04-20 | N/A |
| OpenVPN versions before 2.4.3 and before 2.3.17 are vulnerable to remote denial-of-service when receiving malformed IPv6 packet. | ||||
