CVE-2014-2338 1 Strongswan 1 Strongswan 2025-04-12 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-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-2015-8023 2 Canonical, Strongswan 2 Ubuntu Linux, Strongswan 2025-04-12 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 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-2014-9221 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-2012-2388 1 Strongswan 1 Strongswan 2025-04-11 N/A
The GMP Plugin in strongSwan 4.2.0 through 4.6.3 allows remote attackers to bypass authentication via a (1) empty or (2) zeroed RSA signature, aka "RSA signature verification vulnerability."
CVE-2010-2628 1 Strongswan 1 Strongswan 2025-04-11 N/A
The IKE daemon in strongSwan 4.3.x before 4.3.7 and 4.4.x before 4.4.1 does not properly check the return values of snprintf calls, which allows remote attackers to execute arbitrary code via crafted (1) certificate or (2) identity data that triggers buffer overflows.
CVE-2013-6076 1 Strongswan 1 Strongswan 2025-04-11 N/A
strongSwan 5.0.2 through 5.1.0 allows remote attackers to cause a denial of service (NULL pointer dereference and charon daemon crash) via a crafted IKEv1 fragmentation packet.
CVE-2013-6075 1 Strongswan 1 Strongswan 2025-04-11 N/A
The compare_dn function in utils/identification.c in strongSwan 4.3.3 through 5.1.1 allows (1) remote attackers to cause a denial of service (out-of-bounds read, NULL pointer dereference, and daemon crash) or (2) remote authenticated users to impersonate arbitrary users and bypass access restrictions via a crafted ID_DER_ASN1_DN ID, related to an "insufficient length check" during identity comparison.
CVE-2013-5018 2 Opensuse, Strongswan 2 Opensuse, Strongswan 2025-04-11 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-2013-2944 1 Strongswan 1 Strongswan 2025-04-11 N/A
strongSwan 4.3.5 through 5.0.3, when using the OpenSSL plugin for ECDSA signature verification, allows remote attackers to authenticate as other users via an invalid signature.
CVE-2013-2054 1 Strongswan 1 Strongswan 2025-04-11 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-2023-26463 1 Strongswan 1 Strongswan 2025-02-13 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 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-2019-10155 5 Fedoraproject, Libreswan, Redhat and 2 more 5 Fedora, Libreswan, Enterprise Linux and 2 more 2024-11-21 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 N/A
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 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.
