Any signed-in user can exploit it over the network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2020-4465 in the wild and no public exploit code.\n\nAffected product: IBM MQ Appliance. No package-level version data is available, so check the vendor advisory linked from the reference page.\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-2020-4465/ (Markdown: https://insights.sbomify.com/CVE-2020-4465/index.md)","id":"CVE-2020-4465","markdown":"https://insights.sbomify.com/CVE-2020-4465/index.md","name":"CVE-2020-4465","record":{"aliases":["GHSA-xr77-4rxw-6357"],"analysis":{"component_type":"server_software","fix_type":"patch","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"IBM MQ messaging","requires_auth":"low_privilege","summary":"A remote attacker can cause a denial of service in IBM MQ by exploiting a buffer overflow in channel processing code using an older client.","user_interaction":"not_required","vuln_class":"memory_corruption"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"ibm","cpe":[{"product":"mq_appliance","vendor":"ibm"}],"cvss":{"score":5.3,"severity":"medium","source":"cna","vector":"CVSS:3.0/S:U/PR:L/AC:H/C:N/A:H/AV:N/UI:N/I:N/RL:O/RC:C/E:U","version":"3.0"},"cwes":[{"id":"CWE-120","name":"Buffer Copy without Checking Size of Input"}],"description":"IBM MQ, IBM MQ Appliance, and IBM MQ for HPE NonStop 8.0, 9.1 CD, and 9.1 LTS is vulnerable to a buffer overflow vulnerability due to an error within the channel processing code.
