strongSwan 4.5.x through 5.2.x before 5.2.1 allows remote attackers to cause a denial of service (invalid pointer dereference) via a crafted IKEv2 Key Exchange (KE) message with Diffie-Hellman (DH) group 1025.

Security readout for executives and security teams

This is a remote denial-of-service flaw in older strongSwan IPsec VPN software. A malformed IKEv2 key exchange message can crash affected services, potentially disrupting VPN connectivity. The source bundle does not show code execution, data theft, or confirmed active exploitation. Exposure is most likely on internet-facing or partner-facing IPsec VPN gateways running legacy strongSwan versions from the affected range. Modern distributions may already include patched packages, but long-lived appliances, unmanaged servers, and source-built deployments need verification. Schedule remediation for exposed VPN gateways as a near-term availability fix. It is not shown as actively exploited in the bundle, but VPN outages can disrupt remote access and site-to-site connectivity. Mitigation focus: Upgrade strongSwan to a vendor-fixed release or distribution security package.; Prioritize exposed IKEv2 VPN gateways and externally reachable IPsec endpoints.; Use Ubuntu, Debian, Fedora, openSUSE, or strongSwan advisories for exact package guidance..
