An attacker can exploit it over the internet without logging in, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2023-32067 in the wild and no public exploit code.\n\nAffected product: Debian Debian Linux. 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-2023-32067/ (Markdown: https://insights.sbomify.com/CVE-2023-32067/index.md)","id":"CVE-2023-32067","markdown":"https://insights.sbomify.com/CVE-2023-32067/index.md","name":"CVE-2023-32067","record":{"aliases":["ALSA-2023:3559","ALSA-2023:3584","AZL-26913","AZL-26918","AZL-26921","AZL-26937","AZL-26939","AZL-26942","AZL-34782","AZL-43924","CLSA-2026-1787663550","DEBIAN-CVE-2023-32067","ECHO-d868-b924-469d","GHSA-9g78-jv2r-p7vc","OESA-2023-1302","OESA-2023-1311","OESA-2023-1312","OESA-2023-1313","OESA-2023-1314","RHSA-2023:3559","RHSA-2023:3583","RHSA-2023:3584","RHSA-2023:3660","RHSA-2023:3662","RHSA-2023:3665","RHSA-2023:3677","RHSA-2023:3741","RLSA-2023:3559","RLSA-2023:3584","UBUNTU-CVE-2023-32067"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"c-ares resolver library","requires_auth":"none","summary":"An attacker can cause a denial of service in applications using c-ares by sending forged zero-length UDP packets, triggering an erroneous connection shutdown.","user_interaction":"not_required","vuln_class":"denial_of_service"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"GitHub_M","cpe":[{"product":"c-ares","vendor":"c-ares_project"},{"product":"debian_linux","vendor":"debian"},{"product":"fedora","vendor":"fedoraproject"}],"cvss":{"score":7.5,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H","version":"3.1"},"cwes":[{"id":"CWE-400","name":"Uncontrolled Resource Consumption"}],"description":"c-ares is an asynchronous resolver library. c-ares is vulnerable to denial of service.
