04 Oct 2022 — 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. strongSwan anterior a 5.9.8 permite a atacantes remotos provocar una Denegación de Servicio en el complemento d... • https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/J3GAYIOCSLU57C45CO4UE4IV4JZE4W3L • CWE-400: Uncontrolled Resource Consumption •

25 Jan 2022 — 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.

18 Oct 2021 — The in-memory certificate cache in strongSwan before 5.9.4 has a remote integer overflow upon receiving many requests with different certificates to fill the cache and later trigger the replacement of cache entries. The code attempts to select a less-often-used cache entry by means of a random number generator, but this is not done correctly. Remote code execution might be a slight possibility.

02 Oct 2018 — The gmp plugin in strongSwan before 5.7.1 has a Buffer Overflow via a crafted certificate. El plugin gmp en strongSwan en versiones anteriores a la 5.7.1 tiene un desbordamiento de búfer mediante un certificado manipulado. It was discovered that strongSwan incorrectly handled signature validation in the gmp plugin. A remote attacker could use this issue to cause strongSwan to crash, resulting in a denial of service, or possibly execute arbitrary code. • http://lists.opensuse.org/opensuse-security-announce/2019-11/msg00077.html • CWE-119: Improper Restriction of Operations within the Bounds of a Memory Buffer •

25 Sep 2018 — In verify_emsa_pkcs1_signature() in gmp_rsa_public_key.c in the gmp plugin in strongSwan 4.x and 5.x before 5.7.0, the RSA implementation based on GMP does not reject excess data after the encoded algorithm OID during PKCS#1 v1.5 signature verification.
