| CVE-2018-16151 | 3 Canonical, Debian, Strongswan | 3 Ubuntu Linux, Debian Linux, Strongswan | 2025-12-03 | 5.0 MEDIUM | 7.5 HIGH |
| 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. Similar to the flaw in the same version of strongSwan regarding digestAlgorithm.parameters, a remote attacker can forge signatures when small public exponents are being used, which could lead to impersonation when only an RSA signature is used for IKEv2 authentication. | |||||
| CVE-2022-4967 | 1 Strongswan | 1 Strongswan | 2025-11-06 | N/A | 7.7 HIGH |
| strongSwan versions 5.9.2 through 5.9.5 are affected by authorization bypass through improper validation of certificate with host mismatch (CWE-297). When certificates are used to authenticate clients in TLS-based EAP methods, the IKE or EAP identity supplied by a client is not enforced to be contained in the client's certificate. So clients can authenticate with any trusted certificate and claim an arbitrary IKE/EAP identity as their own. This is problematic if the identity is used to make policy decisions. A fix was released in strongSwan version 5.9.6 in August 2022 (e4b4aabc4996fc61c37deab7858d07bc4d220136). | |||||

| 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. | |||||
| CVE-2015-3991 | 1 Strongswan | 1 Strongswan | 2025-04-20 | 7.5 HIGH | 9.8 CRITICAL |
| strongSwan 5.2.2 and 5.3.0 allows remote attackers to cause a denial of service (daemon crash) or execute arbitrary code. | |||||
| CVE-2014-2891 | 2 Debian, Strongswan | 2 Strongswan, Strongswan | 2025-04-12 | 5.0 MEDIUM | N/A |
| strongSwan before 5.1.2 allows remote attackers to cause a denial of service (NULL pointer dereference and IKE daemon crash) via a crafted ID_DER_ASN1_DN ID payload. | |||||
| CVE-2014-9221 | 5 Canonical, Debian, Fedoraproject and 2 more | 5 Ubuntu Linux, Debian Linux, Fedora and 2 more | 2025-04-12 | 5.0 MEDIUM | N/A |
| 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. | |||||
| CVE-2015-8023 | 2 Canonical, Strongswan | 2 Ubuntu Linux, Strongswan | 2025-04-12 | 5.0 MEDIUM | N/A |
| The server implementation of the EAP-MSCHAPv2 protocol in the eap-mschapv2 plugin in strongSwan 4.2.12 through 5.x before 5.3.4 does not properly validate local state, which allows remote attackers to bypass authentication via an empty Success message in response to an initial Challenge message. | |||||
| CVE-2015-4171 | 3 Canonical, Debian, Strongswan | 4 Ubuntu Linux, Debian Linux, Strongswan and 1 more | 2025-04-12 | 2.6 LOW | N/A |
| strongSwan 4.3.0 through 5.x before 5.3.2 and strongSwan VPN Client before 1.4.6, when using EAP or pre-shared keys for authenticating an IKEv2 connection, does not enforce server authentication restrictions until the entire authentication process is complete, which allows remote servers to obtain credentials by using a valid certificate and then reading the responses. | |||||
| CVE-2014-2338 | 1 Strongswan | 1 Strongswan | 2025-04-12 | 6.4 MEDIUM | N/A |
| IKEv2 in strongSwan 4.0.7 before 5.1.3 allows remote attackers to bypass authentication by rekeying an IKE_SA during (1) initiation or (2) re-authentication, which triggers the IKE_SA state to be set to established. | |||||
| CVE-2023-26463 | 1 Strongswan | 1 Strongswan | 2025-02-07 | N/A | 9.8 CRITICAL |
| strongSwan 5.9.8 and 5.9.9 potentially allows remote code execution because it uses a variable named "public" for two different purposes within the same function. There is initially incorrect access control, later followed by an expired pointer dereference. One attack vector is sending an untrusted client certificate during EAP-TLS. A server is affected only if it loads plugins that implement TLS-based EAP methods (EAP-TLS, EAP-TTLS, EAP-PEAP, or EAP-TNC). This is fixed in 5.9.10. | |||||
| CVE-2021-45079 | 4 Canonical, Debian, Fedoraproject and 1 more | 5 Ubuntu Linux, Debian Linux, Extra Packages For Enterprise Linux and 2 more | 2024-11-21 | 5.8 MEDIUM | 9.1 CRITICAL |
| 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. | |||||
| CVE-2021-41991 | 4 Debian, Fedoraproject, Siemens and 1 more | 46 Debian Linux, Fedora, Cp 1543-1 and 43 more | 2024-11-21 | 5.0 MEDIUM | 7.5 HIGH |
| 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. | |||||
| CVE-2021-41990 | 4 Debian, Fedoraproject, Siemens and 1 more | 37 Debian Linux, Fedora, 6gk5615-0aa00-2aa2 and 34 more | 2024-11-21 | 5.0 MEDIUM | 7.5 HIGH |
| The gmp plugin in strongSwan before 5.9.4 has a remote integer overflow via a crafted certificate with an RSASSA-PSS signature. For example, this can be triggered by an unrelated self-signed CA certificate sent by an initiator. Remote code execution cannot occur. | |||||
| CVE-2019-10155 | 5 Fedoraproject, Libreswan, Redhat and 2 more | 5 Fedora, Libreswan, Enterprise Linux and 2 more | 2024-11-21 | 3.5 LOW | 3.1 LOW |
| The Libreswan Project has found a vulnerability in the processing of IKEv1 informational exchange packets which are encrypted and integrity protected using the established IKE SA encryption and integrity keys, but as a receiver, the integrity check value was not verified. This issue affects versions before 3.29. | |||||
| CVE-2018-6459 | 1 Strongswan | 1 Strongswan | 2024-11-21 | 5.0 MEDIUM | 5.3 MEDIUM |
| The rsa_pss_params_parse function in libstrongswan/credentials/keys/signature_params.c in strongSwan 5.6.1 allows remote attackers to cause a denial of service via a crafted RSASSA-PSS signature that lacks a mask generation function parameter. | |||||
| CVE-2018-5388 | 3 Canonical, Debian, Strongswan | 3 Ubuntu Linux, Debian Linux, Strongswan | 2024-11-21 | 4.0 MEDIUM | 6.5 MEDIUM |
| In stroke_socket.c in strongSwan before 5.6.3, a missing packet length check could allow a buffer underflow, which may lead to resource exhaustion and denial of service while reading from the socket. | |||||
| CVE-2018-17540 | 3 Canonical, Debian, Strongswan | 3 Ubuntu Linux, Debian Linux, Strongswan | 2024-11-21 | 5.0 MEDIUM | 7.5 HIGH |
