{"id":"ALPINE-CVE-2019-12312","details":"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.","modified":"2026-11-03T06:31:34.980002271Z","published":"2019-05-24T14:29:00.230Z","upstream":["CVE-2019-12312"],"references":[{"type":"ADVISORY","url":"https://security.alpinelinux.org/vuln/CVE-2019-12312"}],"affected":[{"package":{"name":"libreswan","ecosystem":"Alpine:v3.11","purl":"pkg:apk/alpine/libreswan?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"3.28-r0"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2019-12312.json"}},{"package":{"name":"libreswan","ecosystem":"Alpine:v3.12","purl":"pkg:apk/alpine/libreswan?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"3.28-r0"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2019-12312.json"}},{"package":{"name":"libreswan","ecosystem":"Alpine:v3.13","purl":"pkg:apk/alpine/libreswan?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"3.28-r0"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2019-12312.json"}},{"package":{"name":"libreswan","ecosystem":"Alpine:v3.14","purl":"pkg:apk/alpine/libreswan?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"3.28-r0"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2019-12312.json"}},{"package":{"name":"libreswan","ecosystem":"Alpine:v3.15","purl":"pkg:apk/alpine/libreswan?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"3.28-r0"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2019-12312.json"}},{"package":{"name":"libreswan","ecosystem":"Alpine:v3.16","purl":"pkg:apk/alpine/libreswan?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"3.28-r0"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2019-12312.json"}},{"package":{"name":"libreswan","ecosystem":"Alpine:v3.17","purl":"pkg:apk/alpine/libreswan?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"3.28-r0"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2019-12312.json"}},{"package":{"name":"libreswan","ecosystem":"Alpine:v3.18","purl":"pkg:apk/alpine/libreswan?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"3.28-r0"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2019-12312.json"}},{"package":{"name":"libreswan","ecosystem":"Alpine:v3.19","purl":"pkg:apk/alpine/libreswan?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"3.28-r0"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2019-12312.json"}},{"package":{"name":"libreswan","ecosystem":"Alpine:v3.20","purl":"pkg:apk/alpine/libreswan?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"3.28-r0"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2019-12312.json"}},{"package":{"name":"libreswan","ecosystem":"Alpine:v3.21","purl":"pkg:apk/alpine/libreswan?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"3.28-r0"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2019-12312.json"}},{"package":{"name":"libreswan","ecosystem":"Alpine:v3.22","purl":"pkg:apk/alpine/libreswan?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"3.28-r0"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2019-12312.json"}},{"package":{"name":"libreswan","ecosystem":"Alpine:v3.23","purl":"pkg:apk/alpine/libreswan?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"3.28-r0"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2019-12312.json"}},{"package":{"name":"libreswan","ecosystem":"Alpine:v3.24","purl":"pkg:apk/alpine/libreswan?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"3.28-r0"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2019-12312.json"}}],"schema_version":"1.9.2","severity":[{"type":"CVSS_V3","score":"CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H"}]}
