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-2023-2829 in the wild and no public exploit code.\n\nAffected product: Isc Bind. 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-2023-2829/ (Markdown: https://insights.sbomify.com/CVE-2023-2829/index.md)","id":"CVE-2023-2829","markdown":"https://insights.sbomify.com/CVE-2023-2829/index.md","name":"CVE-2023-2829","record":{"aliases":["AZL-27305","GHSA-jhg8-766m-r23j"],"analysis":{"component_type":"server_software","fix_type":"patch","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":true,"product_category":"BIND DNS server","requires_auth":"none","summary":"Remote attackers can crash the BIND DNS server by sending malformed NSEC records when the synth-from-dnssec option is enabled.","user_interaction":"not_required","vuln_class":"denial_of_service"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"isc","cpe":[{"product":"bind","vendor":"isc"},{"product":"active_iq_unified_manager","vendor":"netapp"},{"product":"h300s_firmware","vendor":"netapp"},{"product":"h410c_firmware","vendor":"netapp"},{"product":"h410s_firmware","vendor":"netapp"},{"product":"h500s_firmware","vendor":"netapp"},{"product":"h700s_firmware","vendor":"netapp"}],"cvss":{"score":7.5,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H","version":"3.1"},"cwes":[],"description":"A `named` instance configured to run as a DNSSEC-validating recursive resolver with the Aggressive Use of DNSSEC-Validated Cache (RFC 8198) option (`synth-from-dnssec`) enabled can be remotely terminated using a zone with a malformed NSEC record.\nThis issue affects BIND 9 versions 9.16.8-S1 through 9.16.41-S1 and 9.18.11-S1 through 9.18.15-S1.","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":"Malformed NSEC records can cause named to terminate unexpectedly when synth-from-dnssec is enabled","id":"CVE-2023-2829","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"isc:bind","products":["isc:bind","netapp:active_iq_unified_manager","netapp:h300s_firmware","netapp:h410c_firmware","netapp:h410s_firmware","netapp:h500s_firmware","netapp:h700s_firmware"],"type":"denial_of_service","year":"2023"},"n_packages":0,"n_references":2,"next":{"headline":"WordPress WP Testimonials Plugin \u003c= 1.4.2 is vulnerable to Cross Site Request Forgery (CSRF)","id":"CVE-2023-2830"},"packages":[],"prev":{"headline":"named's configured cache size limit can be significantly exceeded","id":"CVE-2023-2828"},"products":["BIND 9"],"published":"2023-06-21","related":[{"cvss_score":10,"headline":"Memory corruption in n/a","id":"CVE-2008-0122","kev_date_added":null,"published":"2008-01-16"},{"cvss_score":10,"headline":"Memory corruption in n/a","id":"CVE-2001-0010","kev_date_added":null,"published":"2001-05-07"},{"cvss_score":10,"headline":"Memory corruption in n/a","id":"CVE-2001-0011","kev_date_added":null,"published":"2001-05-07"},{"cvss_score":10,"headline":"Memory corruption in n/a","id":"CVE-2001-0013","kev_date_added":null,"published":"2001-05-07"},{"cvss_score":10,"headline":"Memory corruption in n/a","id":"CVE-2000-1029","kev_date_added":null,"published":"2000-11-29"},{"cvss_score":10,"headline":"Denial of service in n/a","id":"CVE-1999-0837","kev_date_added":null,"published":"2000-01-04"},{"cvss_score":8.5,"headline":"Denial of service in n/a","id":"CVE-2012-1667","kev_date_added":null,"published":"2012-06-05"}],"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":"FIRST CVSS licence","name":"CVSS (FIRST)"}],"ssvc":{"automatable":"yes","exploitation":"none","technical_impact":"partial"},"state":"PUBLISHED","updated":"2025-02-13","vendors":["ISC"]},"summary":"Remote attackers can crash the BIND DNS server by sending malformed NSEC records when the synth-from-dnssec option is enabled.","url":"https://insights.sbomify.com/CVE-2023-2829/"}
