CVE-2022-40617 5 Canonical, Debian, Fedoraproject and 2 more 5 Ubuntu Linux, Debian Linux, Fedora and 2 more 2025-05-06 7.5 High
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-2017-9022 3 Canonical, Debian, Strongswan 3 Ubuntu Linux, Debian Linux, Strongswan 2025-04-20 N/A
The gmp plugin in strongSwan before 5.5.3 does not properly validate RSA public keys before calling mpz_powm_sec, which allows remote peers to cause a denial of service (floating point exception and process crash) via a crafted certificate.
CVE-2014-2891 2 Debian, Strongswan 2 Strongswan, Strongswan 2025-04-12 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 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-2015-4171 3 Canonical, Debian, Strongswan 4 Ubuntu Linux, Debian Linux, Strongswan and 1 more 2025-04-12 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-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 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 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 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-2018-5388 3 Canonical, Debian, Strongswan 3 Ubuntu Linux, Debian Linux, Strongswan 2024-11-21 N/A
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 N/A
The gmp plugin in strongSwan before 5.7.1 has a Buffer Overflow via a crafted certificate.
CVE-2018-16152 3 Canonical, Debian, Strongswan 3 Ubuntu Linux, Debian Linux, Strongswan 2024-11-21 N/A
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 in the digestAlgorithm.parameters field during PKCS#1 v1.5 signature verification. Consequently, 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. This is a variant of CVE-2006-4790 and CVE-2014-1568.
CVE-2018-16151 3 Canonical, Debian, Strongswan 3 Ubuntu Linux, Debian Linux, Strongswan 2024-11-21 N/A
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-2018-10811 4 Canonical, Debian, Fedoraproject and 1 more 4 Ubuntu Linux, Debian Linux, Fedora and 1 more 2024-11-21 7.5 High
strongSwan 5.6.0 and older allows Remote Denial of Service because of Missing Initialization of a Variable.
