OpenVPN 2.x before 2.0.11, 2.1.x, 2.2.x before 2.2.3, and 2.3.x before 2.3.6 allows remote authenticated users to cause a denial of service (server crash) via a small control channel packet.

Security readout for executives and security teams

This flaw can let a logged-in OpenVPN user crash the VPN server with a malformed small control-channel packet. The business impact is service interruption, not data theft based on the supplied sources. Risk is higher where VPN availability is critical or untrusted users can authenticate. Exposure is limited to environments running the listed vulnerable OpenVPN versions where a remote user can authenticate to the VPN service. Internet-facing VPN endpoints with many users, contractors, or weak account lifecycle controls have the most practical exposure. Treat as a timely availability fix for legacy OpenVPN deployments. It is not described as unauthenticated or data-compromising, but a VPN outage can block operations and incident response access. Mitigation focus: Upgrade OpenVPN to a fixed version or supported vendor package.; Prioritize internet-facing and business-critical VPN servers.; Review vendor advisories for distribution-specific package names and backports..
