{"id":"CVE-2026-61547","summary":"rabbitmq-c: Heap Buffer Overflow in amqp_send_frame() When Serializing Oversized AMQP_FRAME_BODY","details":"rabbitmq-c is a C-language AMQP client library for RabbitMQ. Prior to version 0.17.0, a heap buffer overflow exists in rabbitmq-c when the public amqp_send_frame() API is used to serialize an oversized AMQP_FRAME_BODY. The issue occurs because amqp_frame_to_bytes() copies frame.payload.body_fragment.len bytes into the connection outbound buffer without validating that the body fragment fits within the allocated frame buffer. An application that passes an oversized body frame to amqp_send_frame() can trigger a heap out-of-bounds write, resulting in process crash and memory corruption. This issue has been patched in version 0.17.0.","aliases":["GHSA-hfjv-vcp3-39wh"],"modified":"2026-11-11T02:49:04.891485330Z","published":"2026-11-10T16:21:17.565Z","database_specific":{"cna_assigner":"GitHub_M","cwe_ids":["CWE-787"],"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/61xxx/CVE-2026-61547.json"},"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/61xxx/CVE-2026-61547.json"},{"type":"FIX","url":"https://github.com/alanxz/rabbitmq-c/pull/892"},{"type":"WEB","url":"https://github.com/alanxz/rabbitmq-c/releases/tag/v0.17.0"},{"type":"ADVISORY","url":"https://github.com/alanxz/rabbitmq-c/security/advisories/GHSA-hfjv-vcp3-39wh"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-61547"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/alanxz/rabbitmq-c","events":[{"introduced":"0"},{"fixed":"59df173fff72857896a8257bbfb72d9d29175f1e"}],"database_specific":{"extracted_events":[{"strategy":"StringRangeExpression","range":[{"introduced":"0"},{"fixed":"0.17.0"}],"source":"AFFECTED_FIELD"},{"range":[{"fixed":"59df173fff72857896a8257bbfb72d9d29175f1e"}],"source":"REFERENCES_TAG","original_tag":"v0.17.0"}]}}],"versions":["v0.16.0","v0.15.0","v0.14.0","v0.13.0","v0.12.0","v0.11.0","v0.10.0","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-2026-61547.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:H/I:H/A:H"}]}
