An attacker can exploit it over the internet without logging in, and only if a user opens a file or follows a link.\nExploitation: There is no known exploitation of CVE-2008-4266 in the wild and no public exploit code.\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-2008-4266/ (Markdown: https://insights.sbomify.com/CVE-2008-4266/index.md)","id":"CVE-2008-4266","markdown":"https://insights.sbomify.com/CVE-2008-4266/index.md","name":"CVE-2008-4266","record":{"aliases":["GHSA-xg67-p862-jx9m"],"analysis":{"component_type":"desktop_application","fix_type":"patch","impacts":["code_execution"],"network_reachable":"yes","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 invalid index values causing stack corruption.","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":9.3,"severity":"critical","source":"nvd","vector":"AV:N/AC:M/Au:N/C:C/I:C/A:C","version":"2.0"},"cwes":[{"id":"CWE-399","name":null}],"description":"Array index vulnerability in Microsoft Office Excel 2000 SP3, 2002 SP3, and 2003 SP3; Excel Viewer 2003 Gold and SP3; Office 2004 and 2008 for Mac; and Open XML File Format Converter for Mac allow remote attackers to execute arbitrary code via an Excel spreadsheet with a NAME record that contains an invalid index value, which triggers stack corruption, aka \"Excel Global Array Memory Corruption Vulnerability.\"","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"none_known"},"has_fix":null,"headline":"Memory corruption in n/a","id":"CVE-2008-4266","indexable":true,"kev":null,"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":"2008"},"n_packages":0,"n_references":7,"next":{"headline":"DO NOT USE THIS CANDIDATE NUMBER.","id":"CVE-2008-4267"},"packages":[],"prev":{"headline":"Memory corruption in n/a","id":"CVE-2008-4265"},"products":["n/a"],"published":"2008-12-10","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":7.8,"headline":"Microsoft Excel Featheader Record Memory Corruption","id":"CVE-2009-3129","kev_date_added":"2022-03-03","published":"2009-11-11"},{"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":"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":"2024-08-07","vendors":["n/a"]},"summary":"Remote attackers can execute arbitrary code by tricking users into opening a malicious Excel spreadsheet with invalid index values causing stack corruption.","url":"https://insights.sbomify.com/CVE-2008-4266/"}
