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-2018-14626 in the wild and no public exploit code.\n\nAffected product: Powerdns Recursor. 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-2018-14626/ (Markdown: https://insights.sbomify.com/CVE-2018-14626/index.md)","id":"CVE-2018-14626","markdown":"https://insights.sbomify.com/CVE-2018-14626/index.md","name":"CVE-2018-14626","record":{"aliases":["DEBIAN-CVE-2018-14626","GHSA-pvqq-mpxw-8x79","UBUNTU-CVE-2018-14626"],"analysis":{"component_type":"server_software","fix_type":"upgrade","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"PowerDNS server","requires_auth":"none","summary":"Attackers can cause denial of service in PowerDNS Authoritative Server and Recursor by polluting the packet cache with crafted queries.","user_interaction":"not_required","vuln_class":"denial_of_service"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"redhat","cpe":[{"product":"authoritative","vendor":"powerdns"},{"product":"recursor","vendor":"powerdns"}],"cvss":{"score":5.3,"severity":"medium","source":"cna","vector":"CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:L","version":"3.0"},"cwes":[{"id":"CWE-400","name":"Uncontrolled Resource Consumption"}],"description":"PowerDNS Authoritative Server 4.1.0 up to 4.1.4 inclusive and PowerDNS Recursor 4.0.0 up to 4.1.4 inclusive are vulnerable to a packet cache pollution via crafted query that can lead to denial of service.","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 pdns","id":"CVE-2018-14626","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"powerdns:recursor","products":["powerdns:recursor"],"type":"denial_of_service","year":"2018"},"n_packages":0,"n_references":3,"next":{"headline":"Security feature bypass in JBoss/WildFly","id":"CVE-2018-14627"},"packages":[],"prev":{"headline":"Race condition in kernel","id":"CVE-2018-14625"},"products":["pdns","pdns-recursor"],"published":"2018-11-29","related":[{"cvss_score":9.8,"headline":"Use after free in n/a","id":"CVE-2020-24698","kev_date_added":null,"published":"2020-10-02"},{"cvss_score":8.1,"headline":"Race condition in n/a","id":"CVE-2020-24696","kev_date_added":null,"published":"2020-10-02"},{"cvss_score":7.8,"headline":"Denial of service in n/a","id":"CVE-2015-5470","kev_date_added":null,"published":"2015-11-02"},{"cvss_score":7.5,"headline":"Insufficient Validation of Autoprimary SOA Queries","id":"CVE-2026-42001","kev_date_added":null,"published":"2026-05-21"},{"cvss_score":7.5,"headline":"Denial of service in n/a","id":"CVE-2020-24697","kev_date_added":null,"published":"2020-10-02"},{"cvss_score":7.5,"headline":"Denial of service in n/a","id":"CVE-2016-5426","kev_date_added":null,"published":"2016-09-21"},{"cvss_score":7.5,"headline":"Denial of service in n/a","id":"CVE-2016-5427","kev_date_added":null,"published":"2016-09-21"}],"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":"2024-08-05","vendors":["The PowerDNS Project"]},"summary":"Attackers can cause denial of service in PowerDNS Authoritative Server and Recursor by polluting the packet cache with crafted queries.","url":"https://insights.sbomify.com/CVE-2018-14626/"}
