| CVE-2023-23009 | 2 Debian, Libreswan | 2 Debian Linux, Libreswan | 2023-03-07 | N/A | 6.5 MEDIUM |
| Libreswan 4.9 allows remote attackers to cause a denial of service (assert failure and daemon restart) via crafted TS payload with an incorrect selector length. | |||||
| CVE-2015-3240 | 1 Libreswan | 1 Libreswan | 2023-02-12 | 4.3 MEDIUM | N/A |
| The pluto IKE daemon in libreswan before 3.15 and Openswan before 2.6.45, when built with NSS, allows remote attackers to cause a denial of service (assertion failure and daemon restart) via a zero DH g^x value in a KE payload in a IKE packet. | |||||
| CVE-2015-3204 | 1 Libreswan | 1 Libreswan | 2023-02-12 | 5.0 MEDIUM | N/A |
| libreswan 3.9 through 3.12 allows remote attackers to cause a denial of service (daemon restart) via an IKEv1 packet with (1) unassigned bits set in the IPSEC DOI value or (2) the next payload value set to ISAKMP_NEXT_SAK. | |||||
| CVE-2016-5391 | 2 Fedoraproject, Libreswan | 2 Fedora, Libreswan | 2023-02-12 | 5.0 MEDIUM | 7.5 HIGH |
| libreswan before 3.18 allows remote attackers to cause a denial of service (NULL pointer dereference and pluto daemon restart). | |||||
| CVE-2022-23094 | 3 Debian, Fedoraproject, Libreswan | 3 Debian Linux, Fedora, Libreswan | 2022-01-24 | 5.0 MEDIUM | 7.5 HIGH |
| Libreswan 4.2 through 4.5 allows remote attackers to cause a denial of service (NULL pointer dereference and daemon crash) via a crafted IKEv1 packet because pluto/ikev1.c wrongly expects that a state object exists. This is fixed in 4.6. | |||||
| CVE-2020-1763 | 1 Libreswan | 1 Libreswan | 2021-05-05 | 5.0 MEDIUM | 7.5 HIGH |
| An out-of-bounds buffer read flaw was found in the pluto daemon of libreswan from versions 3.27 till 3.31 where, an unauthenticated attacker could use this flaw to crash libreswan by sending specially-crafted IKEv1 Informational Exchange packets. The daemon respawns after the crash. | |||||
| 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-2019-12312 | 1 Libreswan | 1 Libreswan | 2020-08-24 | 5.0 MEDIUM | 7.5 HIGH |
| In Libreswan 3.27 an assertion failure can lead to a pluto IKE daemon restart. An attacker can trigger a NULL pointer dereference by initiating an IKEv2 IKE_SA_INIT exchange, followed by a bogus INFORMATIONAL exchange instead of the normallly expected IKE_AUTH exchange. This affects send_v2N_spi_response_from_state() in programs/pluto/ikev2_send.c that will then trigger a NULL pointer dereference leading to a restart of libreswan. | |||||
| CVE-2013-7294 | 1 Libreswan | 1 Libreswan | 2018-01-02 | 5.0 MEDIUM | N/A |
| The ikev2parent_inI1outR1 function in pluto/ikev2_parent.c in libreswan before 3.7 allows remote attackers to cause a denial of service (restart) via an IKEv2 I1 notification without a KE payload. | |||||
| CVE-2013-6467 | 1 Libreswan | 1 Libreswan | 2017-08-28 | 5.0 MEDIUM | N/A |
| Libreswan 3.7 and earlier allows remote attackers to cause a denial of service (NULL pointer dereference and IKE daemon restart) via IKEv2 packets that lack expected payloads. | |||||
| CVE-2016-3071 | 2 Fedoraproject, Libreswan | 2 Fedora, Libreswan | 2017-02-06 | 5.0 MEDIUM | 7.5 HIGH |
| Libreswan 3.16 might allow remote attackers to cause a denial of service (daemon restart) via an IKEv2 aes_xcbc transform. | |||||
| CVE-2016-5361 | 1 Libreswan | 1 Libreswan | 2017-01-17 | 5.0 MEDIUM | 7.5 HIGH |
| programs/pluto/ikev1.c in libreswan before 3.17 retransmits in initial-responder states, which allows remote attackers to cause a denial of service (traffic amplification) via a spoofed UDP packet. NOTE: the original behavior complies with the IKEv1 protocol, but has a required security update from the libreswan vendor; as of 2016-06-10, it is expected that several other IKEv1 implementations will have vendor-required security updates, with separate CVE IDs assigned to each. | |||||
| CVE-2013-4564 | 1 Libreswan | 1 Libreswan | 2014-02-25 | 5.0 MEDIUM | N/A |
| Libreswan 3.6 allows remote attackers to cause a denial of service (crash) via a small length value and (1) no version or (2) an invalid major number in an IKE packet. | |||||
| CVE-2013-7283 | 1 Libreswan | 1 Libreswan | 2014-01-10 | 9.3 HIGH | N/A |
| Race condition in the libreswan.spec files for Red Hat Enterprise Linux (RHEL) and Fedora packages in libreswan 3.6 has unspecified impact and attack vectors, involving the /var/tmp/libreswan-nss-pwd temporary file. | |||||
| CVE-2013-2052 | 1 Libreswan | 1 Libreswan | 2013-10-11 | 5.1 MEDIUM | N/A |
| Buffer overflow in the atodn function in libreswan 3.0 and 3.1, 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. | |||||
