DATE CVE VULNERABILITY TITLE RISK
2022-10-31 CVE-2022-40617 Resource Exhaustion vulnerability in multiple products
strongSwan before 5.9.8 allows remote attackers to cause a denial of service in the revocation plugin by sending a crafted end-entity (and intermediate CA) certificate that contains a CRL/OCSP URL that points to a server (under the attacker's control) that doesn't properly respond but (for example) just does nothing after the initial TCP handshake, or sends an excessive amount of application data.
7.5
2022-01-31 CVE-2021-45079 NULL Pointer Dereference vulnerability in multiple products
In strongSwan before 5.9.5, a malicious responder can send an EAP-Success message too early without actually authenticating the client and (in the case of EAP methods with mutual authentication and EAP-only authentication for IKEv2) even without server authentication.
