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-2009-0537 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-2009-0537/ (Markdown: https://insights.sbomify.com/CVE-2009-0537/index.md)","id":"CVE-2009-0537","markdown":"https://insights.sbomify.com/CVE-2009-0537/index.md","name":"CVE-2009-0537","record":{"aliases":["GHSA-9fjq-qvpr-gcq2"],"analysis":{"component_type":"operating_system","fix_type":"patch","impacts":["denial_of_service"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"OpenBSD libc","requires_auth":"none","summary":"An integer overflow in libc allows local attackers to crash applications like du or rm via deep directory trees, causing denial of service.","user_interaction":"not_required","vuln_class":"integer_overflow"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"interix","vendor":"microsoft"},{"product":"openbsd","vendor":"openbsd"}],"cvss":{"score":4.9,"severity":"medium","source":"nvd","vector":"AV:L/AC:L/Au:N/C:N/I:N/A:C","version":"2.0"},"cwes":[{"id":"CWE-189","name":null}],"description":"Integer overflow in the fts_build function in fts.c in libc in (1) OpenBSD 4.4 and earlier and (2) Microsoft Interix 6.0 build 10.0.6030.0 allows context-dependent attackers to cause a denial of service (application crash) via a deep directory tree, related to the fts_level structure member, as demonstrated by (a) du, (b) rm, (c) chmod, and (d) chgrp on OpenBSD; and (e) SearchIndexer.exe on Vista Enterprise.","ecosystems":[],"exploits":{"exploitdb":1,"first_seen":"2009-03-05","github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[{"date":"2009-03-05","kind":"exploitdb","ref":"8163","stars":null,"title":"Libc - 'libc:fts_*()' Local Denial of Service"}],"tier":"weaponised"},"has_fix":null,"headline":"Integer overflow in n/a","id":"CVE-2009-0537","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"openbsd:openbsd","products":["openbsd:openbsd"],"type":"integer_overflow","year":"2009"},"n_packages":0,"n_references":7,"next":{"headline":"Memory corruption in n/a","id":"CVE-2009-0538"},"packages":[],"prev":{"headline":"Privilege escalation in n/a","id":"CVE-2009-0536"},"products":["n/a"],"published":"2009-03-09","related":[{"cvss_score":7.8,"headline":"Microsoft Windows Privilege Escalation","id":"CVE-2004-0210","kev_date_added":"2022-03-03","published":"2004-07-14"},{"cvss_score":7.5,"headline":"Buffer overflow in telnet server in Windows 2000 and Interix 2.2 allows remote attackers to execute arbitrary code via malformed protocol options.","id":"CVE-2002-0020","kev_date_added":null,"published":"2002-06-25"}],"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":"2024-08-07","vendors":["n/a"]},"summary":"An integer overflow in libc allows local attackers to crash applications like du or rm via deep directory trees, causing denial of service.","url":"https://insights.sbomify.com/CVE-2009-0537/"}
