| CVE-2013-2054 | 1 Strongswan | 1 Strongswan | 2023-11-07 | 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-2023-26463 | 1 Strongswan | 1 Strongswan | 2023-05-17 | 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-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-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-2015-4171 | 3 Canonical, Debian, Strongswan | 4 Ubuntu Linux, Debian Linux, Strongswan and 1 more | 2017-11-08 | 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-2012-2388 | 1 Strongswan | 1 Strongswan | 2017-08-29 | 7.5 HIGH | 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-2004-0590 | 3 Frees Wan, Openswan, Strongswan | 4 Frees Wan, Super Frees Wan, Openswan and 1 more | 2017-07-11 | 10.0 HIGH | N/A |
| FreeS/WAN 1.x and 2.x, and other related products including superfreeswan 1.x, openswan 1.x before 1.0.6, openswan 2.x before 2.1.4, and strongSwan before 2.1.3, allows remote attackers to authenticate using spoofed PKCS#7 certificates in which a self-signed certificate identifies an alternate Certificate Authority (CA) and spoofed issuer and subject. | |||||
| CVE-2014-2338 | 1 Strongswan | 1 Strongswan | 2016-11-28 | 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-2013-6075 | 1 Strongswan | 1 Strongswan | 2013-11-21 | 5.0 MEDIUM | 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-2013-6076 | 1 Strongswan | 1 Strongswan | 2013-11-21 | 5.0 MEDIUM | 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-2008-4551 | 1 Strongswan | 1 Strongswan | 2011-03-08 | 5.0 MEDIUM | N/A |
| strongSwan 4.2.6 and earlier allows remote attackers to cause a denial of service (daemon crash) via an IKE_SA_INIT message with a large number of NULL values in a Key Exchange payload, which triggers a NULL pointer dereference for the return value of the mpz_export function in the GNU Multiprecision Library (GMP). | |||||
| CVE-2010-2628 | 1 Strongswan | 1 Strongswan | 2010-08-24 | 7.5 HIGH | 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-2009-2661 | 1 Strongswan | 1 Strongswan | 2009-11-24 | 5.0 MEDIUM | N/A |
| The asn1_length function in strongSwan 2.8 before 2.8.11, 4.2 before 4.2.17, and 4.3 before 4.3.3 does not properly handle X.509 certificates with crafted Relative Distinguished Names (RDNs), which allows remote attackers to cause a denial of service (pluto IKE daemon crash) via malformed ASN.1 data. NOTE: this is due to an incomplete fix for CVE-2009-2185. | |||||
| CVE-2009-1958 | 1 Strongswan | 1 Strongswan | 2009-10-14 | 5.0 MEDIUM | N/A |
| charon/sa/tasks/child_create.c in the charon daemon in strongSWAN before 4.3.1 switches the NULL checks for TSi and TSr payloads, which allows remote attackers to cause a denial of service via an IKE_AUTH request without a (1) TSi or (2) TSr traffic selector. | |||||
| CVE-2009-1957 | 1 Strongswan | 1 Strongswan | 2009-10-14 | 5.0 MEDIUM | N/A |
| charon/sa/ike_sa.c in the charon daemon in strongSWAN before 4.3.1 allows remote attackers to cause a denial of service (NULL pointer dereference and crash) via an invalid IKE_SA_INIT request that triggers "an incomplete state," followed by a CREATE_CHILD_SA request. | |||||
