An attacker can exploit it over the internet without logging in, with no action from the victim."},"fix_prompt":"Check this codebase for CVE-2018-0732 and fix it if it is affected.\n\nWhat it is: CVE-2018-0732 is a high-severity denial of service vulnerability in Canonical Ubuntu Linux, published on 12 Jun 2018. 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-2018-0732 in the wild and no public exploit code.\n\nAffected product: Canonical Ubuntu 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-2018-0732/ (Markdown: https://insights.sbomify.com/CVE-2018-0732/index.md)","id":"CVE-2018-0732","markdown":"https://insights.sbomify.com/CVE-2018-0732/index.md","name":"CVE-2018-0732","record":{"aliases":["ALPINE-CVE-2018-0732","DEBIAN-CVE-2018-0732","GHSA-497c-86pp-222m","SUSE-SU-2018:1887-1","SUSE-SU-2018:1887-2","SUSE-SU-2018:1968-1","SUSE-SU-2018:2036-1","SUSE-SU-2018:2041-1","SUSE-SU-2018:2207-1","SUSE-SU-2018:2956-1","UBUNTU-CVE-2018-0732"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"OpenSSL library","requires_auth":"none","summary":"A malicious server can cause a client hang and denial of service by sending a large DH parameter during TLS handshake.","user_interaction":"not_required","vuln_class":"denial_of_service"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"openssl","cpe":[{"product":"ubuntu_linux","vendor":"canonical"},{"product":"debian_linux","vendor":"debian"},{"product":"node.js","vendor":"nodejs"},{"product":"openssl","vendor":"openssl"}],"cvss":{"score":7.5,"severity":"high","source":"nvd","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-320","name":null}],"description":"During key agreement in a TLS handshake using a DH(E) based ciphersuite a malicious server can send a very large prime value to the client.
