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-2011-4869 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-2011-4869/ (Markdown: https://insights.sbomify.com/CVE-2011-4869/index.md)","id":"CVE-2011-4869","markdown":"https://insights.sbomify.com/CVE-2011-4869/index.md","name":"CVE-2011-4869","record":{"aliases":["DEBIAN-CVE-2011-4869","GHSA-6xqx-v8qv-h8xm"],"analysis":{"component_type":"server_software","fix_type":"upgrade","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"DNS resolver","requires_auth":"none","summary":"Remote attackers can crash the Unbound DNS resolver daemon by sending malformed NSEC3 responses, causing a denial of service.","user_interaction":"not_required","vuln_class":"denial_of_service"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"unbound","vendor":"unbound"}],"cvss":{"score":7.8,"severity":"high","source":"nvd","vector":"AV:N/AC:L/Au:N/C:N/I:N/A:C","version":"2.0"},"cwes":[{"id":"CWE-399","name":null}],"description":"validator/val_nsec3.c in Unbound before 1.4.13p2 does not properly perform proof processing for NSEC3-signed zones, which allows remote DNS servers to cause a denial of service (daemon crash) via a malformed response that lacks expected NSEC3 records, a different vulnerability than CVE-2011-4528.","ecosystems":[],"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":"Denial of service in n/a","id":"CVE-2011-4869","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"denial_of_service","year":"2011"},"n_packages":0,"n_references":8,"next":{"headline":"Memory corruption in n/a","id":"CVE-2011-4870"},"packages":[],"prev":{"headline":"Null dereference in n/a","id":"CVE-2011-4868"},"products":["n/a"],"published":"2011-12-20","related":[{"cvss_score":6.4,"headline":"The resolver in Unbound before 1.4.11 overwrites cached server names and TTL values in NS records during the processing of a response to an","id":"CVE-2012-1192","kev_date_added":null,"published":"2012-02-17"},{"cvss_score":5,"headline":"Use after free in n/a","id":"CVE-2011-4528","kev_date_added":null,"published":"2011-12-20"}],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"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":"2024-08-07","vendors":["n/a"]},"summary":"Remote attackers can crash the Unbound DNS resolver daemon by sending malformed NSEC3 responses, causing a denial of service.","url":"https://insights.sbomify.com/CVE-2011-4869/"}
