It can only be exploited from the same machine or local network, with no action from the victim.\nExploitation: It is not confirmed as exploited in the wild, but public exploit code for CVE-2001-1559 exists.\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-2001-1559/ (Markdown: https://insights.sbomify.com/CVE-2001-1559/index.md)","id":"CVE-2001-1559","markdown":"https://insights.sbomify.com/CVE-2001-1559/index.md","name":"CVE-2001-1559","record":{"aliases":["GHSA-c4g9-53v4-f2qg"],"analysis":{"component_type":"operating_system","fix_type":"patch","impacts":["denial_of_service"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"OpenBSD kernel","requires_auth":"low_privilege","summary":"Local users can cause a denial of service in OpenBSD via a null dereference in the uipc system calls due to incorrect return value handling.","user_interaction":"not_required","vuln_class":"null_dereference"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"openbsd","vendor":"openbsd"}],"cvss":{"score":5.5,"severity":"medium","source":"nvd","vector":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H","version":"3.1"},"cwes":[{"id":"CWE-476","name":"NULL Pointer Dereference"}],"description":"The uipc system calls (uipc_syscalls.c) in OpenBSD 2.9 and 3.0 provide user mode return instead of versus rval kernel mode values to the fdrelease function, which allows local users to cause a denial of service and trigger a null dereference.","ecosystems":[],"exploits":{"exploitdb":1,"first_seen":"2001-12-03","github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[{"date":"2001-12-03","kind":"exploitdb","ref":"21167","stars":null,"title":"OpenBSD 2.x/3.0 - User Mode Return Value Denial of Service"}],"tier":"weaponised"},"has_fix":null,"headline":"Null dereference in n/a","id":"CVE-2001-1559","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"openbsd:openbsd","products":["openbsd:openbsd"],"type":"null_dereference","year":"2001"},"n_packages":0,"n_references":3,"next":{"headline":"Denial of service in n/a","id":"CVE-2001-1560"},"packages":[],"prev":{"headline":"Unknown vulnerability in IP defragmenter (frag2) in Snort before 1.8.3 allows attackers to cause a denial of service (crash).","id":"CVE-2001-1558"},"products":["n/a"],"published":"2005-07-14","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":"CWE Terms of Use","name":"CWE (MITRE)"},{"class":"attribution","licence":"FIRST CVSS licence","name":"CVSS (FIRST)"},{"class":"attribution","licence":"GPL-2.0-or-later","name":"Exploit-DB"}],"ssvc":{"automatable":null,"exploitation":null,"technical_impact":null},"state":"PUBLISHED","updated":"2024-09-16","vendors":["n/a"]},"summary":"Local users can cause a denial of service in OpenBSD via a null dereference in the uipc system calls due to incorrect return value handling.","url":"https://insights.sbomify.com/CVE-2001-1559/"}
