An attacker can exploit it over the internet without logging in, and only if a user opens a file or follows a link.\nExploitation: It is not confirmed as exploited in the wild, but public exploit code for CVE-2011-0105 exists.\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-2011-0105/ (Markdown: https://insights.sbomify.com/CVE-2011-0105/index.md)","id":"CVE-2011-0105","markdown":"https://insights.sbomify.com/CVE-2011-0105/index.md","name":"CVE-2011-0105","record":{"aliases":["GHSA-rpg9-x63j-3644"],"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 crafted Excel file that triggers a buffer overflow via uninitialized memory.","user_interaction":"required","vuln_class":"memory_corruption"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"microsoft","cpe":[{"product":"excel","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-119","name":"Improper Restriction of Operations within the Bounds of a Memory Buffer"}],"description":"Microsoft Excel 2002 SP3, Office 2004 and 2008 for Mac, and Open XML File Format Converter for Mac obtain a certain length value from an uninitialized memory location, which allows remote attackers to trigger a buffer overflow and execute arbitrary code via a crafted Excel file, aka \"Excel Data Initialization Vulnerability.\"","ecosystems":[],"exploits":{"exploitdb":1,"first_seen":"2011-08-09","github_poc":0,"max_poc_stars":null,"metasploit":1,"nuclei":0,"refs":[{"date":"2011-08-09","kind":"metasploit","ref":"exploit/windows/fileformat/ms11_021_xlb_bof","stars":null,"title":"MS11-021 Microsoft Office 2007 Excel .xlb Buffer Overflow"},{"date":"2011-11-05","kind":"exploitdb","ref":"18087","stars":null,"title":"Microsoft Excel 2007 - '.xlb' Local Buffer Overflow (MS11-021) (Metasploit)"}],"tier":"weaponised"},"has_fix":null,"headline":"Memory corruption in n/a","id":"CVE-2011-0105","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"microsoft:excel","products":["microsoft:excel","microsoft:office","microsoft:open_xml_file_format_converter"],"type":"memory_corruption","year":"2011"},"n_packages":0,"n_references":6,"next":{"headline":"DO NOT USE THIS CANDIDATE NUMBER.","id":"CVE-2011-0106"},"packages":[],"prev":{"headline":"Memory corruption in n/a","id":"CVE-2011-0104"},"products":["n/a"],"published":"2011-04-13","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)"},{"class":"attribution","licence":"BSD-3-Clause","name":"Metasploit"},{"class":"attribution","licence":"GPL-2.0-or-later","name":"Exploit-DB"}],"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 Excel file that triggers a buffer overflow via uninitialized memory.","url":"https://insights.sbomify.com/CVE-2011-0105/"}
