2023-05-29 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. Libreswan 7.5
2023-05-17 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... Libreswan, Enterprise_linux, Enterprise_linux_eus, Enterprise_linux_server_aus, Enterprise_linux_server_tus 7.5
2023-02-21 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. Debian_linux, Libreswan 6.5
2015-07-01 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. Libreswan N/A
2015-11-09 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. Libreswan N/A
2017-06-13 CVE-2016-5391 libreswan before 3.18 allows remote attackers to cause a denial of service (NULL pointer dereference and pluto daemon restart). Fedora, Libreswan 7.5
2022-01-15 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. Debian_linux, Fedora, Libreswan 7.5
2020-05-12 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. Libreswan 7.5
2019-06-12 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. Fedora, Libreswan, Strongswan, Openswan 3.1
2019-05-24 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. Libreswan 7.5
