An attacker can exploit it over the internet without logging in, and only if a user opens a file or follows a link.\nExploitation: It is not confirmed as exploited in the wild, but public exploit code for CVE-2026-44236 exists.\n\nAffected packages and fixed versions:\n- rabbitmq-c (Bitnami): affected all versions; fixed in 0.16.0\n\nTask:\n1. Search the dependency manifests and lockfiles (for example package.json, package-lock.json, requirements.txt, poetry.lock, uv.lock, pom.xml, build.gradle, go.mod, Cargo.lock, Gemfile.lock) and any Dockerfiles for the affected packages, including transitive dependencies.\n2. If an affected version is in use, upgrade it to the fixed version for its release line with the project's package manager, so the lockfile is regenerated. Prefer the smallest upgrade that fixes it.\n3. If there is no fix, or the upgrade would break the build, do not guess: explain the risk and the safest workaround instead.\n4. Run the tests and summarise what changed and why.\n5. If nothing in the project is affected, say so and change nothing.\n\nReference: https://insights.sbomify.com/CVE-2026-44236/ (Markdown: https://insights.sbomify.com/CVE-2026-44236/index.md)","id":"CVE-2026-44236","markdown":"https://insights.sbomify.com/CVE-2026-44236/index.md","name":"CVE-2026-44236","record":{"aliases":["ALSA-2026:75582","ALSA-2026:82094","ALSA-2026:84795","AZL-105087","BIT-rabbitmq-c-2026-44236","CLSA-2026-1792594240","CLSA-2026-1792765036","DEBIAN-CVE-2026-44236","ECHO-6381-0eb9-8dbd","GHSA-jh48-qjf5-fx5v","RHSA-2026:75582","RHSA-2026:82094","RHSA-2026:84795","RLSA-2026:75582","RLSA-2026:82094","RLSA-2026:84795","UBUNTU-CVE-2026-44236"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["denial_of_service","code_execution"],"network_reachable":"yes","non_default_config":false,"product_category":"AMQP client library","requires_auth":"none","summary":"A malicious AMQP server can trigger a heap buffer overflow in the rabbitmq-c client library during login, causing denial of service or potential code execution.","user_interaction":"required","vuln_class":"memory_corruption"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"GitHub_M","cpe":[],"cvss":{"score":7.1,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:N/I:L/A:H","version":"3.1"},"cwes":[{"id":"CWE-122","name":"Heap-based Buffer Overflow"}],"description":"rabbitmq-c is a C-language AMQP client library for RabbitMQ. Prior to 0.16.0, a malicious AMQP server can send an undersized connection.tune.frame_max value during amqp_login(), and rabbitmq-c accepts the value in amqp_login_inner() in librabbitmq/amqp_socket.c. amqp_tune_connection() in librabbitmq/amqp_connection.c uses frame_max to reallocate the outbound buffer without enforcing AMQP_FRAME_MIN_SIZE. Immediate serialization of connection.tune-ok through amqp_frame_to_bytes() writes beyond the undersized heap allocation, causing memory corruption and likely denial of service. An on-path attacker can also trigger the flaw against plaintext AMQP traffic. Code execution is theoretically possible but was not demonstrated.
