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-2025-59029 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-2025-59029/ (Markdown: https://insights.sbomify.com/CVE-2025-59029/index.md)","id":"CVE-2025-59029","markdown":"https://insights.sbomify.com/CVE-2025-59029/index.md","name":"CVE-2025-59029","record":{"aliases":["DEBIAN-CVE-2025-59029","GHSA-2gr2-cm9q-vr3v","UBUNTU-CVE-2025-59029"],"analysis":{"component_type":"server_software","fix_type":"patch","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"DNS recursor","requires_auth":"none","summary":"An attacker can cause a denial of service in PowerDNS Recursor by triggering an assertion failure through crafted DNS record requests.","user_interaction":"not_required","vuln_class":"denial_of_service"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"OX","cpe":[{"product":"recursor","vendor":"powerdns"}],"cvss":{"score":5.3,"severity":"medium","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:L","version":"3.1"},"cwes":[{"id":"CWE-617","name":"Reachable Assertion"}],"description":"An attacker can trigger an assertion failure by requesting crafted DNS records, waiting for them to be inserted into the records cache, then send a query with qtype set to ANY.","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":"Internal logic flaw in cache management can lead to a denial of service in PowerDNS Recursor","id":"CVE-2025-59029","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"powerdns:recursor","products":["powerdns:recursor"],"type":"denial_of_service","year":"2025"},"n_packages":0,"n_references":1,"next":{"headline":"Insufficient validation of incoming notifies over TCP can lead to a denial of service in Recursor","id":"CVE-2025-59030"},"packages":[],"prev":{"headline":"Denial of service in OX Dovecot Pro","id":"CVE-2025-59028"},"products":["Recursor"],"published":"2025-12-09","related":[{"cvss_score":10,"headline":"Memory corruption in n/a","id":"CVE-2009-4009","kev_date_added":null,"published":"2010-01-08"},{"cvss_score":8.8,"headline":"Memory corruption in n/a","id":"CVE-2020-10030","kev_date_added":null,"published":"2020-05-19"},{"cvss_score":8.2,"headline":"Crafted delegations or IP fragments can poison cached delegations in Recursor","id":"CVE-2025-59023","kev_date_added":null,"published":"2026-02-09"},{"cvss_score":7.5,"headline":"Insufficient validation of incoming notifies over TCP can lead to a denial of service in Recursor","id":"CVE-2025-59030","kev_date_added":null,"published":"2025-12-09"},{"cvss_score":7.5,"headline":"Denial of service in n/a","id":"CVE-2023-22617","kev_date_added":null,"published":"2023-01-21"},{"cvss_score":7.5,"headline":"Memory corruption in pdns-recursor","id":"CVE-2018-16855","kev_date_added":null,"published":"2018-12-03"},{"cvss_score":7.5,"headline":"Other in n/a","id":"CVE-2009-4010","kev_date_added":null,"published":"2010-01-08"}],"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":"yes","exploitation":"none","technical_impact":"partial"},"state":"PUBLISHED","updated":"2025-12-09","vendors":["PowerDNS"]},"summary":"An attacker can cause a denial of service in PowerDNS Recursor by triggering an assertion failure through crafted DNS record requests.","url":"https://insights.sbomify.com/CVE-2025-59029/"}
