| CVE | 摘要 | 来源 | 最高 CVSS | EPSS % | 公开时间 | 更新时间 |
|---|---|---|---|---|---|---|
| CVE-2024-3652 | The Libreswan Project was notified of an issue causing libreswan to restart when using IKEv1 without specifying an esp= line. When the peer requests AES-GMAC, libreswan's default proposal handler causes an assertion failure and crashes and restarts. IKEv2 connections are not affected. | d42dc95b-23f1-4e06-9076-20753a0fb0df | 6.5 | 0.80% | 2024-04-10 | 2026-06-17 |
| CVE-2023-38712 | An issue was discovered in Libreswan 3.x and 4.x before 4.12. When an IKEv1 ISAKMP SA Informational Exchange packet contains a Delete/Notify payload followed by further Notifies that act on the ISAKMP SA, such as a duplicated Delete/Notify message, a NULL pointer dereference on the deleted state causes the pluto daemon to crash and restart. | [email protected] | 6.5 | 0.69% | 2023-08-25 | 2026-06-17 |
| CVE-2023-38711 | An issue was discovered in Libreswan before 4.12. When an IKEv1 Quick Mode connection configured with ID_IPV4_ADDR or ID_IPV6_ADDR receives an IDcr payload with ID_FQDN, a NULL pointer dereference causes a crash and restart of the pluto daemon. NOTE: the earliest affected version is 4.6. | [email protected] | 6.5 | 0.69% | 2023-08-25 | 2026-06-17 |
| CVE-2023-38710 | An issue was discovered in Libreswan before 4.12. When an IKEv2 Child SA REKEY packet contains an invalid IPsec protocol ID number of 0 or 1, an error notify INVALID_SPI is sent back. The notify payload's protocol ID is copied from the incoming packet, but the code that verifies outgoing packets fails an assertion that the protocol ID must be ESP (2) or AH(3) and causes the pluto daemon to crash and restart. NOTE: the earliest affected version is 3.20. | [email protected] | 6.5 | 0.69% | 2023-08-25 | 2026-06-17 |
| CVE-2023-30570 | pluto in Libreswan before 4.11 allows a denial of service (responder SPI mishandling and daemon crash) via unauthenticated IKEv1 Aggressive Mode packets. The earliest affected version is 3.28. | [email protected] | 7.5 | 1.18% | 2023-05-28 | 2026-06-17 |
| CVE-2023-2295 | A vulnerability was found in the libreswan library. This security issue occurs when an IKEv1 Aggressive Mode packet is received with only unacceptable crypto algorithms, and the response packet is not sent with a zero responder SPI. When a subsequent packet is received where the sender reuses the libreswan responder SPI as its own initiator SPI, the pluto daemon state machine crashes. No remote code execution is possible. This CVE exists because of a CVE-2023-30570 security regression for libres | [email protected] | 7.5 | 1.58% | 2023-05-17 | 2026-06-17 |
| CVE-2023-23009 | 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. | [email protected] | 6.5 | 1.61% | 2023-02-21 | 2026-06-17 |
| CVE-2022-23094 | 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. | [email protected] | 7.5 | 2.70% | 2022-01-14 | 2026-06-17 |
| CVE-2020-1763 | 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. | [email protected] | 7.5 | 3.29% | 2020-05-12 | 2026-06-16 |
| CVE-2019-10155 | 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. | [email protected] | 3.1 | 0.51% | 2019-06-12 | 2026-06-16 |
| CVE-2019-12312 | 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. | [email protected] | 7.5 | 2.75% | 2019-05-24 | 2026-06-16 |
| CVE-2016-5391 | libreswan before 3.18 allows remote attackers to cause a denial of service (NULL pointer dereference and pluto daemon restart). | [email protected] | 7.5 | 2.96% | 2017-06-13 | 2026-06-16 |
| CVE-2016-5361 | 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. | [email protected] | 7.5 | 2.77% | 2016-06-16 | 2026-06-16 |
| CVE-2016-3071 | Libreswan 3.16 might allow remote attackers to cause a denial of service (daemon restart) via an IKEv2 aes_xcbc transform. | [email protected] | 7.5 | 2.56% | 2016-04-18 | 2026-06-16 |
| CVE-2015-3240 | 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. | [email protected] | 4.3 | 2.77% | 2015-11-09 | 2026-06-16 |
| CVE-2015-3204 | 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. | [email protected] | 5.0 | 2.59% | 2015-07-01 | 2026-06-16 |
| CVE-2013-6467 | 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. | [email protected] | 5.0 | 2.45% | 2014-01-26 | 2026-06-16 |
| CVE-2013-7294 | 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. | [email protected] | 5.0 | 2.55% | 2014-01-16 | 2026-06-16 |
| CVE-2013-7283 | 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. | [email protected] | 9.3 | 1.63% | 2014-01-09 | 2026-06-16 |
| CVE-2013-4564 | 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. | [email protected] | 5.0 | 2.64% | 2014-01-07 | 2026-06-16 |
