| CVE-2013-2054 | 1 Strongswan | 1 Strongswan | 2023-02-12 | 5.1 MEDIUM | N/A |
| Buffer overflow in the atodn function in strongSwan 2.0.0 through 4.3.4, when Opportunistic Encryption is enabled and an RSA key is being used, allows remote attackers to cause a denial of service (pluto IKE daemon crash) and possibly execute arbitrary code via crafted DNS TXT records. NOTE: this might be the same vulnerability as CVE-2013-2053 and CVE-2013-2054. | |||||
| CVE-2022-40617 | 4 Canonical, Debian, Fedoraproject and 1 more | 4 Ubuntu Linux, Debian Linux, Fedora and 1 more | 2023-01-27 | N/A | 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-2021-45079 | 4 Canonical, Debian, Fedoraproject and 1 more | 5 Ubuntu Linux, Debian Linux, Extra Packages For Enterprise Linux and 2 more | 2022-07-12 | 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 | 2022-04-12 | 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 | 2022-04-12 | 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-2018-10811 | 4 Canonical, Debian, Fedoraproject and 1 more | 4 Ubuntu Linux, Debian Linux, Fedora and 1 more | 2021-05-18 | 5.0 MEDIUM | 7.5 HIGH |
| strongSwan 5.6.0 and older allows Remote Denial of Service because of Missing Initialization of a Variable. | |||||
| CVE-2019-10155 | 5 Fedoraproject, Libreswan, Redhat and 2 more | 5 Fedora, Libreswan, Enterprise Linux and 2 more | 2020-09-30 | 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 | 2020-03-29 | 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-2018-17540 | 3 Canonical, Debian, Strongswan | 3 Ubuntu Linux, Debian Linux, Strongswan | 2019-11-30 | 5.0 MEDIUM | 7.5 HIGH |
| The gmp plugin in strongSwan before 5.7.1 has a Buffer Overflow via a crafted certificate. | |||||
| CVE-2018-16151 | 3 Canonical, Debian, Strongswan | 3 Ubuntu Linux, Debian Linux, Strongswan | 2019-11-30 | 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-2018-16152 | 3 Canonical, Debian, Strongswan | 3 Ubuntu Linux, Debian Linux, Strongswan | 2019-11-30 | 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 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-2018-5388 | 3 Canonical, Debian, Strongswan | 3 Ubuntu Linux, Debian Linux, Strongswan | 2019-10-09 | 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-2017-9023 | 1 Strongswan | 1 Strongswan | 2019-10-02 | 4.3 MEDIUM | 7.5 HIGH |
| The ASN.1 parser in strongSwan before 5.5.3 improperly handles CHOICE types when the x509 plugin is enabled, which allows remote attackers to cause a denial of service (infinite loop) via a crafted certificate. | |||||
| CVE-2009-2185 | 2 Strongswan, Xelerance | 2 Strongswan, Openswan | 2019-07-29 | 5.0 MEDIUM | N/A |
| The ASN.1 parser (pluto/asn1.c, libstrongswan/asn1/asn1.c, libstrongswan/asn1/asn1_parser.c) in (a) strongSwan 2.8 before 2.8.10, 4.2 before 4.2.16, and 4.3 before 4.3.2; and (b) openSwan 2.6 before 2.6.22 and 2.4 before 2.4.15 allows remote attackers to cause a denial of service (pluto IKE daemon crash) via an X.509 certificate with (1) crafted Relative Distinguished Names (RDNs), (2) a crafted UTCTIME string, or (3) a crafted GENERALIZEDTIME string. | |||||
| CVE-2009-0790 | 2 Strongswan, Xelerance | 2 Strongswan, Openswan | 2019-07-29 | 5.0 MEDIUM | N/A |
| The pluto IKE daemon in Openswan and Strongswan IPsec 2.6 before 2.6.21 and 2.4 before 2.4.14, and Strongswan 4.2 before 4.2.14 and 2.8 before 2.8.9, allows remote attackers to cause a denial of service (daemon crash and restart) via a crafted (1) R_U_THERE or (2) R_U_THERE_ACK Dead Peer Detection (DPD) IPsec IKE Notification message that triggers a NULL pointer dereference related to inconsistent ISAKMP state and the lack of a phase2 state association in DPD. | |||||
| CVE-2017-9022 | 3 Canonical, Debian, Strongswan | 3 Ubuntu Linux, Debian Linux, Strongswan | 2019-04-16 | 5.0 MEDIUM | 7.5 HIGH |
| 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-2013-5018 | 2 Opensuse, Strongswan | 2 Opensuse, Strongswan | 2018-10-30 | 4.3 MEDIUM | N/A |
| The is_asn1 function in strongSwan 4.1.11 through 5.0.4 does not properly validate the return value of the asn1_length function, which allows remote attackers to cause a denial of service (segmentation fault) via a (1) XAuth username, (2) EAP identity, or (3) PEM encoded file that starts with a 0x04, 0x30, or 0x31 character followed by an ASN.1 length value that triggers an integer overflow. | |||||
| CVE-2014-9221 | 5 Canonical, Debian, Fedoraproject and 2 more | 5 Ubuntu Linux, Debian Linux, Fedora and 2 more | 2018-10-30 | 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-2015-3991 | 1 Strongswan | 1 Strongswan | 2018-08-13 | 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. | |||||
