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-2011-1987 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-2011-1987/ (Markdown: https://insights.sbomify.com/CVE-2011-1987/index.md)","id":"CVE-2011-1987","markdown":"https://insights.sbomify.com/CVE-2011-1987/index.md","name":"CVE-2011-1987","record":{"aliases":["GHSA-4h74-gfxr-p5q7"],"analysis":{"component_type":"desktop_application","fix_type":"patch","impacts":["code_execution"],"network_reachable":"yes","non_default_config":false,"product_category":"Microsoft Excel","requires_auth":"none","summary":"Remote attackers can execute arbitrary code by tricking users into opening a crafted spreadsheet in Microsoft Excel.","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":"office_compatibility_pack","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-119","name":"Improper Restriction of Operations within the Bounds of a Memory Buffer"}],"description":"Array index error in Microsoft Excel 2003 SP3 and 2007 SP2; Excel in Office 2007 SP2; Excel 2010 Gold and SP1; Excel in Office 2010 Gold and SP1; Office 2004, 2008, and 2011 for Mac; Open XML File Format Converter for Mac; Excel Viewer SP2; and Office Compatibility Pack for Word, Excel, and PowerPoint 2007 File Formats SP2 allows remote attackers to execute arbitrary code via a crafted spreadsheet, aka \"Excel Out of Bounds Array Indexing 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-2011-1987","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"microsoft:excel","products":["microsoft:excel","microsoft:excel_viewer","microsoft:office","microsoft:office_compatibility_pack","microsoft:open_xml_file_format_converter"],"type":"memory_corruption","year":"2011"},"n_packages":0,"n_references":3,"next":{"headline":"Memory corruption in n/a","id":"CVE-2011-1988"},"packages":[],"prev":{"headline":"Use after free in n/a","id":"CVE-2011-1986"},"products":["n/a"],"published":"2011-09-15","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":"2024-08-06","vendors":["n/a"]},"summary":"Remote attackers can execute arbitrary code by tricking users into opening a crafted spreadsheet in Microsoft Excel.","url":"https://insights.sbomify.com/CVE-2011-1987/"}
