| Format string vulnerability in the foreign_option function in options.c for OpenVPN 2.0.x allows remote clients to execute arbitrary code via format string specifiers in a push of the dhcp-option command option. | ||||
| CVE-2005-2532 | 1 Openvpn | 1 Openvpn | 2026-04-16 | N/A |
| OpenVPN before 2.0.1 does not properly flush the OpenSSL error queue when a packet can not be decrypted by the server, which allows remote authenticated attackers to cause a denial of service (client disconnection) via a large number of packets that can not be decrypted. | ||||
| CVE-2005-2534 | 1 Openvpn | 1 Openvpn | 2026-04-16 | N/A |
