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-2018-18408 in the wild and no public exploit code.\n\nAffected product: Broadcom Tcpreplay. 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-2018-18408/ (Markdown: https://insights.sbomify.com/CVE-2018-18408/index.md)","id":"CVE-2018-18408","markdown":"https://insights.sbomify.com/CVE-2018-18408/index.md","name":"CVE-2018-18408","record":{"aliases":["DEBIAN-CVE-2018-18408","GHSA-rc6v-3qc7-jpvm","UBUNTU-CVE-2018-18408"],"analysis":{"component_type":"network_device","fix_type":"upgrade","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"Tcpreplay tcpbridge","requires_auth":"none","summary":"A use-after-free in Tcpreplay's tcpbridge binary allows attackers to cause a denial of service or potentially other impacts.","user_interaction":"not_required","vuln_class":"use_after_free"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"tcpreplay","vendor":"broadcom"},{"product":"fedora","vendor":"fedoraproject"}],"cvss":{"score":9.8,"severity":"critical","source":"nvd","vector":"CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H","version":"3.0"},"cwes":[{"id":"CWE-416","name":"Use After Free"}],"description":"A use-after-free was discovered in the tcpbridge binary of Tcpreplay 4.3.0 beta1.
