It can only be exploited from the same machine or local network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2023-29323 in the wild and no public exploit code.\n\nAffected product: Openbsd Openbsd. 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-2023-29323/ (Markdown: https://insights.sbomify.com/CVE-2023-29323/index.md)","id":"CVE-2023-29323","markdown":"https://insights.sbomify.com/CVE-2023-29323/index.md","name":"CVE-2023-29323","record":{"aliases":["DEBIAN-CVE-2023-29323","GHSA-c3j9-w5jx-cmmq","UBUNTU-CVE-2023-29323"],"analysis":{"component_type":"server_software","fix_type":"patch","impacts":["denial_of_service"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"OpenSMTPD mail server","requires_auth":"low_privilege","summary":"A remote attacker can cause a denial of service in OpenSMTPD by sending a connection from a local scoped IPv6 address, crashing the smtpd process.","user_interaction":"not_required","vuln_class":"denial_of_service"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"openbsd","vendor":"openbsd"},{"product":"opensmtpd","vendor":"opensmtpd"}],"cvss":{"score":7.8,"severity":"high","source":"nvd","vector":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H","version":"3.1"},"cwes":[],"description":"ascii_load_sockaddr in smtpd in OpenBSD before 7.1 errata 024 and 7.2 before errata 020, and OpenSMTPD Portable before 7.0.0-portable commit f748277, can abort upon a connection from a local, scoped IPv6 address.","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-2023-29323","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"openbsd:openbsd","products":["openbsd:openbsd"],"type":"denial_of_service","year":"2023"},"n_packages":0,"n_references":9,"next":{"headline":"Windows MSHTML Platform Security Feature Bypass Vulnerability","id":"CVE-2023-29324"},"packages":[],"prev":{"headline":"Adobe Experience Manager | Cross-site Scripting (Reflected XSS) (CWE-79)","id":"CVE-2023-29322"},"products":["n/a"],"published":"2023-04-04","related":[{"cvss_score":10,"headline":"Memory corruption in n/a","id":"CVE-2007-1365","kev_date_added":null,"published":"2007-03-10"},{"cvss_score":10,"headline":"Integer overflow in n/a","id":"CVE-2004-0220","kev_date_added":null,"published":"2004-03-25"},{"cvss_score":10,"headline":"Memory corruption in n/a","id":"CVE-2004-0083","kev_date_added":null,"published":"2004-02-14"},{"cvss_score":10,"headline":"Memory corruption in n/a","id":"CVE-2004-0084","kev_date_added":null,"published":"2004-02-14"},{"cvss_score":10,"headline":"Memory corruption in n/a","id":"CVE-2001-0284","kev_date_added":null,"published":"2001-05-07"},{"cvss_score":10,"headline":"Memory corruption in n/a","id":"CVE-2000-1010","kev_date_added":null,"published":"2001-01-22"},{"cvss_score":9.8,"headline":"Auth bypass in n/a","id":"CVE-2020-16088","kev_date_added":null,"published":"2020-07-28"}],"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":"no","exploitation":"none","technical_impact":"partial"},"state":"PUBLISHED","updated":"2025-11-04","vendors":["n/a"]},"summary":"A remote attacker can cause a denial of service in OpenSMTPD by sending a connection from a local scoped IPv6 address, crashing the smtpd process.","url":"https://insights.sbomify.com/CVE-2023-29323/"}
