{"id":"CVE-2019-18609","details":"An issue was discovered in amqp_handle_input in amqp_connection.c in rabbitmq-c 0.9.0. There is an integer overflow that leads to heap memory corruption in the handling of CONNECTION_STATE_HEADER. A rogue server could return a malicious frame header that leads to a smaller target_size value than needed. This condition is then carried on to a memcpy function that copies too much data into a heap buffer.","modified":"2026-07-08T17:18:33.073398Z","published":"2019-12-01T22:15:10.897Z","related":["ALSA-2020:4445","openSUSE-SU-2024:11293-1"],"database_specific":{"unresolved_ranges":[{"cpes":["cpe:2.3:o:canonical:ubuntu_linux:14.04:*:*:*:esm:*:*:*","cpe:2.3:o:canonical:ubuntu_linux:16.04:*:*:*:lts:*:*:*","cpe:2.3:o:canonical:ubuntu_linux:18.04:*:*:*:lts:*:*:*","cpe:2.3:o:canonical:ubuntu_linux:19.04:*:*:*:*:*:*:*","cpe:2.3:o:canonical:ubuntu_linux:19.10:*:*:*:*:*:*:*"],"extracted_events":[{"introduced":"14.04"},{"last_affected":"14.04"},{"introduced":"16.04"},{"last_affected":"16.04"},{"introduced":"18.04"},{"last_affected":"18.04"},{"introduced":"19.04"},{"last_affected":"19.04"},{"introduced":"19.10"},{"last_affected":"19.10"}],"source":"CPE_STRING","vendor_product":"canonical:ubuntu_linux"},{"cpes":["cpe:2.3:o:debian:debian_linux:8.0:*:*:*:*:*:*:*"],"extracted_events":[{"introduced":"8.0"},{"last_affected":"8.0"}],"source":"CPE_STRING","vendor_product":"debian:debian_linux"},{"source":"CPE_STRING","vendor_product":"fedoraproject:fedora","cpes":["cpe:2.3:o:fedoraproject:fedora:30:*:*:*:*:*:*:*","cpe:2.3:o:fedoraproject:fedora:31:*:*:*:*:*:*:*"],"extracted_events":[{"introduced":"30"},{"last_affected":"30"},{"introduced":"31"},{"last_affected":"31"}]}]},"references":[{"type":"WEB","url":"https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/WA7CPNVYMF6OQNIYNLWUY6U2GTKFOKH3/"},{"type":"WEB","url":"https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/XQER6XTKYMHNQR7QTHW7DJAH645WQROU/"},{"type":"ADVISORY","url":"https://github.com/alanxz/rabbitmq-c/blob/master/ChangeLog.md"},{"type":"ADVISORY","url":"https://lists.debian.org/debian-lts-announce/2019/12/msg00004.html"},{"type":"ADVISORY","url":"https://security.gentoo.org/glsa/202003-07"},{"type":"ADVISORY","url":"https://usn.ubuntu.com/4214-1/"},{"type":"ADVISORY","url":"https://usn.ubuntu.com/4214-2/"},{"type":"REPORT","url":"https://news.ycombinator.com/item?id=21681976"},{"type":"FIX","url":"https://github.com/alanxz/rabbitmq-c/commit/fc85be7123050b91b054e45b91c78d3241a5047a"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/alanxz/rabbitmq-c","events":[{"introduced":"0"},{"fixed":"ffe918a5fcef72038a88054dca3c56762b1953d4"},{"fixed":"fc85be7123050b91b054e45b91c78d3241a5047a"}],"database_specific":{"cpe":"cpe:2.3:a:rabbitmq-c_project:rabbitmq-c:*:*:*:*:*:*:*:*","extracted_events":[{"introduced":"0"},{"fixed":"0.10.0"}],"source":["CPE_RANGE","REFERENCES"]}}],"versions":["v0.9.0-master","v0.8.0","v0.7.1","v0.7.0","v0.6.0","v0.5.2","v0.5.1","v0.5.0","v0.4.0","v0.4.0-test","v0.3.0","rabbitmq-c-v0.3.0","v0.2","0.2","v0.1","librabbitmq-0.1-amqp_0_8"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2019-18609.json","vanir_signatures_modified":"2026-07-08T17:18:33Z","vanir_signatures":[{"source":"https://github.com/alanxz/rabbitmq-c/commit/fc85be7123050b91b054e45b91c78d3241a5047a","target":{"file":"librabbitmq/amqp_connection.c"},"deprecated":false,"digest":{"line_hashes":["243814341639543304421666209824618441313","183455278906321621184992196995879566177","182357040532403947509468435054005069746","225885130475099735426407665019057949072","236275910161916524206322804826057425579","44673271485574882728132486074926918671"],"threshold":0.9},"id":"CVE-2019-18609-10f09550","signature_type":"Line","signature_version":"v1"},{"signature_type":"Function","signature_version":"v1","source":"https://github.com/alanxz/rabbitmq-c/commit/fc85be7123050b91b054e45b91c78d3241a5047a","target":{"file":"librabbitmq/amqp_connection.c","function":"amqp_handle_input"},"deprecated":false,"digest":{"function_hash":"238469019489558242787949093743451899054","length":3589},"id":"CVE-2019-18609-2c47032f"}]}}],"schema_version":"1.7.5","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H"}]}
