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-2017-1000231 in the wild and no public exploit code.\n\nAffected product: n/a. 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-2017-1000231/ (Markdown: https://insights.sbomify.com/CVE-2017-1000231/index.md)","id":"CVE-2017-1000231","markdown":"https://insights.sbomify.com/CVE-2017-1000231/index.md","name":"CVE-2017-1000231","record":{"aliases":["ALPINE-CVE-2017-1000231","AZL-10412","DEBIAN-CVE-2017-1000231","DLA-1182-1","GHSA-r9hw-j2qr-6m8c","UBUNTU-CVE-2017-1000231","openSUSE-SU-2024:10912-1"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["denial_of_service","code_execution"],"network_reachable":"yes","non_default_config":false,"product_category":"ldns DNS library","requires_auth":"none","summary":"A double-free vulnerability in the ldns library allows attackers to cause denial of service or potentially execute arbitrary code.","user_interaction":"not_required","vuln_class":"use_after_free"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"ldns","vendor":"nlnetlabs"}],"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-415","name":"Double Free"}],"description":"A double-free vulnerability in parse.c in ldns 1.7.0 have unspecified impact and attack vectors.","ecosystems":["openSUSE:Tumbleweed"],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"none_known"},"has_fix":true,"headline":"Use after free in n/a","id":"CVE-2017-1000231","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"use_after_free","year":"2017"},"n_packages":1,"n_references":3,"next":{"headline":"Use after free in n/a","id":"CVE-2017-1000232"},"packages":[{"ecosystem":"openSUSE:Tumbleweed","fixed":["1.7.1-1.11"],"introduced":["0"],"last_affected":[],"package":"ldns","purl":"pkg:rpm/opensuse/ldns\u0026distro=openSUSE%20Tumbleweed","source":"openSUSE-SU-2024:10912-1"}],"prev":{"headline":"Denial of service in n/a","id":"CVE-2017-1000230"},"products":["n/a"],"published":"2017-11-17","related":[{"cvss_score":9.8,"headline":"Use after free in n/a","id":"CVE-2017-1000232","kev_date_added":null,"published":"2017-11-17"},{"cvss_score":8.2,"headline":"Insufficient verification that responses belong to a query","id":"CVE-2026-10846","kev_date_added":null,"published":"2026-06-10"},{"cvss_score":7.5,"headline":"Information disclosure in n/a","id":"CVE-2020-19861","kev_date_added":null,"published":"2022-01-21"},{"cvss_score":6.8,"headline":"Memory corruption in n/a","id":"CVE-2011-3581","kev_date_added":null,"published":"2011-11-04"},{"cvss_score":6.5,"headline":"Information disclosure in n/a","id":"CVE-2020-19860","kev_date_added":null,"published":"2022-01-21"},{"cvss_score":6.4,"headline":"Memory corruption in n/a","id":"CVE-2009-1086","kev_date_added":null,"published":"2009-03-25"}],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"class":"attribution","licence":"CC BY 4.0","name":"SUSE","prefix":"openSUSE"},{"class":"attribution","licence":"US public information, NVD API terms","name":"NVD"},{"class":"attribution","licence":"CWE Terms of Use","name":"CWE (MITRE)"},{"class":"attribution","licence":"FIRST CVSS licence","name":"CVSS (FIRST)"}],"ssvc":{"automatable":null,"exploitation":null,"technical_impact":null},"state":"PUBLISHED","updated":"2024-08-05","vendors":["n/a"]},"summary":"A double-free vulnerability in the ldns library allows attackers to cause denial of service or potentially execute arbitrary code.","url":"https://insights.sbomify.com/CVE-2017-1000231/"}
