An attacker needs administrator access to exploit it, and only if a user opens a file or follows a link.\nExploitation: There is no known exploitation of CVE-2023-32726 in the wild and no public exploit code.\n\nAffected product: Zabbix. 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-2023-32726/ (Markdown: https://insights.sbomify.com/CVE-2023-32726/index.md)","id":"CVE-2023-32726","markdown":"https://insights.sbomify.com/CVE-2023-32726/index.md","name":"CVE-2023-32726","record":{"aliases":["DEBIAN-CVE-2023-32726","GHSA-fqr7-2x83-wf2r","UBUNTU-CVE-2023-32726"],"analysis":{"component_type":"server_software","fix_type":"patch","impacts":["denial_of_service","data_read"],"network_reachable":"yes","non_default_config":false,"product_category":"Zabbix monitoring server","requires_auth":"high_privilege","summary":"A buffer overread in Zabbix's DNS response handling allows attackers to cause denial of service or disclose sensitive memory contents.","user_interaction":"required","vuln_class":"memory_corruption"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"Zabbix","cpe":[{"product":"zabbix-agent","vendor":"zabbix"}],"cvss":{"score":3.9,"severity":"low","source":"cna","vector":"CVSS:3.1/AV:N/AC:H/PR:H/UI:R/S:U/C:L/I:L/A:L","version":"3.1"},"cwes":[{"id":"CWE-754","name":"Improper Check for Unusual or Exceptional Conditions"}],"description":"The vulnerability is caused by improper check for check if RDLENGTH does not overflow the buffer in response from DNS server.","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":"Possible buffer overread from reading DNS responses","id":"CVE-2023-32726","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"memory_corruption","year":"2023"},"n_packages":0,"n_references":4,"next":{"headline":"Code execution vulnerability in icmpping","id":"CVE-2023-32727"},"packages":[],"prev":{"headline":"Leak of zbx_session cookie when using a scheduled report that includes a dashboard with a URL widget.","id":"CVE-2023-32725"},"products":["Zabbix"],"published":"2023-12-18","related":[],"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":"2025-11-03","vendors":["Zabbix"]},"summary":"A buffer overread in Zabbix's DNS response handling allows attackers to cause denial of service or disclose sensitive memory contents.","url":"https://insights.sbomify.com/CVE-2023-32726/"}
