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.

Security readout for executives and security teams

CVE-2005-2532 is an OpenVPN denial-of-service issue. Authenticated remote users could send many packets the server cannot decrypt, causing client disconnections. It affects OpenVPN versions before 2.0.1. The sources do not indicate data theft, privilege escalation, or confirmed active exploitation. Exposure is most likely where legacy OpenVPN servers or distribution packages older than 2.0.1 remain deployed. Risk depends on whether authenticated users can reach the VPN service and whether vendor backported fixes are present. Treat as a legacy VPN availability risk. Prioritize remediation if affected OpenVPN servers still support business access, but urgency is lower than unauthenticated remote code execution or data exposure issues. Mitigation focus: Upgrade OpenVPN to 2.0.1 or later where supported.; Apply relevant vendor security updates from Debian, Mandriva, or your distribution.; Check vendor guidance for any backported fixed package versions..
