It can only be exploited from the same machine or local network, and only if a user opens a file or follows a link.\nExploitation: Yes. Attackers have exploited CVE-2009-3129 in the wild since at least 3 Mar 2022.\n\nAffected product: Microsoft Excel. 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-2009-3129/ (Markdown: https://insights.sbomify.com/CVE-2009-3129/index.md)","id":"CVE-2009-3129","markdown":"https://insights.sbomify.com/CVE-2009-3129/index.md","name":"CVE-2009-3129","record":{"aliases":["GHSA-8325-hmcc-g9mq"],"analysis":{"component_type":"desktop_application","fix_type":"patch","impacts":["code_execution"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Microsoft Office Excel","requires_auth":"none","summary":"Remote attackers can execute arbitrary code by tricking users into opening a malicious Excel spreadsheet with a malformed FEATHEADER record.","user_interaction":"required","vuln_class":"memory_corruption"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"microsoft","cpe":[{"product":"excel","vendor":"microsoft"},{"product":"excel_viewer","vendor":"microsoft"},{"product":"office","vendor":"microsoft"},{"product":"open_xml_file_format_converter","vendor":"microsoft"}],"cvss":{"score":7.8,"severity":"high","source":"cisa-adp","vector":"CVSS:3.1/AV:L/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-787","name":"Out-of-bounds Write"}],"description":"Microsoft Office Excel 2002 SP3, 2003 SP3, and 2007 SP1 and SP2; Office 2004 and 2008 for Mac; Open XML File Format Converter for Mac; Office Excel Viewer 2003 SP3; Office Excel Viewer SP1 and SP2; and Office Compatibility Pack for Word, Excel, and PowerPoint 2007 File Formats SP1 and SP2 allows remote attackers to execute arbitrary code via a spreadsheet with a FEATHEADER record containing an invalid cbHdrData size element that affects a pointer offset, aka \"Excel Featheader Record Memory Corruption Vulnerability.\"","ecosystems":[],"exploits":{"exploitdb":2,"first_seen":"2009-11-10","github_poc":0,"max_poc_stars":null,"metasploit":1,"nuclei":0,"refs":[{"date":"2009-11-10","kind":"metasploit","ref":"exploit/windows/fileformat/ms09_067_excel_featheader","stars":null,"title":"MS09-067 Microsoft Excel Malformed FEATHEADER Record Vulnerability"},{"date":"2010-08-21","kind":"exploitdb","ref":"14706","stars":null,"title":"Microsoft Excel - FEATHEADER Record (MS09-067)"},{"date":"2010-09-25","kind":"exploitdb","ref":"16625","stars":null,"title":"Microsoft Excel - Malformed FEATHEADER Record (MS09-067) (Metasploit)"}],"tier":"exploited"},"has_fix":null,"headline":"Microsoft Excel Featheader Record Memory Corruption","id":"CVE-2009-3129","indexable":true,"kev":{"dateAdded":"2022-03-03","dueDate":"2022-03-24","knownRansomwareCampaignUse":"Unknown","product":"Excel","requiredAction":"Apply updates per vendor instructions.","vendorProject":"Microsoft","vulnerabilityName":"Microsoft Excel Featheader Record Memory Corruption Vulnerability"},"kind":"cve","links":{"ecosystem":null,"product":"microsoft:excel","products":["microsoft:excel","microsoft:excel_viewer","microsoft:office","microsoft:open_xml_file_format_converter"],"type":"memory_corruption","year":"2009"},"n_packages":0,"n_references":10,"next":{"headline":"Memory corruption in n/a","id":"CVE-2009-3130"},"packages":[],"prev":{"headline":"Memory corruption in n/a","id":"CVE-2009-3128"},"products":["n/a"],"published":"2009-11-11","related":[{"cvss_score":8.8,"headline":"Microsoft Excel Remote Code Execution","id":"CVE-2019-1297","kev_date_added":"2022-03-03","published":"2019-09-11"},{"cvss_score":8.8,"headline":"Microsoft Office Remote Code Execution","id":"CVE-2009-0238","kev_date_added":"2026-04-14","published":"2009-02-25"},{"cvss_score":7.8,"headline":"Microsoft Office Security Feature Bypass","id":"CVE-2016-7262","kev_date_added":"2022-03-03","published":"2016-12-20"},{"cvss_score":9.8,"headline":"Code injection in n/a","id":"CVE-2008-0081","kev_date_added":null,"published":"2008-01-16"},{"cvss_score":9.3,"headline":"Memory corruption in n/a","id":"CVE-2015-6040","kev_date_added":null,"published":"2015-12-09"},{"cvss_score":9.3,"headline":"Memory corruption in n/a","id":"CVE-2015-6122","kev_date_added":null,"published":"2015-12-09"}],"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":"open","licence":"CC0 1.0","name":"CISA KEV"},{"class":"attribution","licence":"CWE Terms of Use","name":"CWE (MITRE)"},{"class":"attribution","licence":"FIRST CVSS licence","name":"CVSS (FIRST)"},{"class":"attribution","licence":"BSD-3-Clause","name":"Metasploit"},{"class":"attribution","licence":"GPL-2.0-or-later","name":"Exploit-DB"}],"ssvc":{"automatable":"no","exploitation":"active","technical_impact":"total"},"state":"PUBLISHED","updated":"2025-10-22","vendors":["n/a"]},"summary":"Remote attackers can execute arbitrary code by tricking users into opening a malicious Excel spreadsheet with a malformed FEATHEADER record.","url":"https://insights.sbomify.com/CVE-2009-3129/"}
