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: There is no known exploitation of CVE-2018-8432 in the wild and no public exploit code.\n\nAffected product: Microsoft Excel Viewer. 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-2018-8432/ (Markdown: https://insights.sbomify.com/CVE-2018-8432/index.md)","id":"CVE-2018-8432","markdown":"https://insights.sbomify.com/CVE-2018-8432/index.md","name":"CVE-2018-8432","record":{"aliases":["GHSA-w9fx-69v3-2jgx"],"analysis":{"component_type":"operating_system","fix_type":"patch","impacts":["code_execution"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Microsoft Graphics Components","requires_auth":"none","summary":"Remote code execution via memory handling flaws in Microsoft Graphics Components affects Windows and Office products.","user_interaction":"required","vuln_class":"memory_corruption"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"microsoft","cpe":[{"product":"excel_viewer","vendor":"microsoft"},{"product":"office","vendor":"microsoft"},{"product":"office_365_proplus","vendor":"microsoft"},{"product":"office_compatibility_pack","vendor":"microsoft"},{"product":"powerpoint_viewer","vendor":"microsoft"},{"product":"windows_10","vendor":"microsoft"},{"product":"windows_7","vendor":"microsoft"},{"product":"windows_server_2008","vendor":"microsoft"},{"product":"windows_server_2019","vendor":"microsoft"},{"product":"word_viewer","vendor":"microsoft"}],"cvss":{"score":7.8,"severity":"high","source":"nvd","vector":"CVSS:3.0/AV:L/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H","version":"3.0"},"cwes":[],"description":"A remote code execution vulnerability exists in the way that Microsoft Graphics Components handle objects in memory, aka \"Microsoft Graphics Components Remote Code Execution Vulnerability.\" This affects Windows 7, Microsoft Office, Microsoft Office Word Viewer, Office 365 ProPlus, Microsoft Excel Viewer, Microsoft PowerPoint Viewer, Windows Server 2019, Windows Server 2008 R2, Windows 10, Windows Server 2008.","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 Microsoft Excel Viewer","id":"CVE-2018-8432","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"microsoft:excel_viewer","products":["microsoft:excel_viewer","microsoft:office","microsoft:office_365_proplus","microsoft:office_compatibility_pack","microsoft:windows_10","microsoft:windows_7","microsoft:windows_server_2008","microsoft:windows_server_2019","microsoft:word_viewer"],"type":"memory_corruption","year":"2018"},"n_packages":0,"n_references":3,"next":{"headline":"Information disclosure in Windows 10","id":"CVE-2018-8433"},"packages":[],"prev":{"headline":"Cross-site scripting in Microsoft SharePoint","id":"CVE-2018-8431"},"products":["Microsoft Excel Viewer","Microsoft Office","Microsoft Office Word Viewer","Microsoft PowerPoint Viewer","Office","Windows 10","Windows 7","Windows Server 2008","Windows Server 2008 R2","Windows Server 2019"],"published":"2018-10-10","related":[{"cvss_score":8.8,"headline":"Microsoft MSHTML Remote Code Execution","id":"CVE-2019-0541","kev_date_added":"2021-11-03","published":"2019-01-08"},{"cvss_score":8.8,"headline":"Microsoft PowerPoint Memory Corruption","id":"CVE-2015-2424","kev_date_added":"2022-03-03","published":"2015-07-14"},{"cvss_score":7.8,"headline":"Microsoft Graphics Component Memory Corruption","id":"CVE-2013-3906","kev_date_added":"2022-02-15","published":"2013-11-06"},{"cvss_score":9.3,"headline":"Memory corruption in n/a","id":"CVE-2008-0113","kev_date_added":null,"published":"2008-03-11"},{"cvss_score":5.5,"headline":"Security feature bypass in Microsoft Excel Viewer","id":"CVE-2019-0540","kev_date_added":null,"published":"2019-03-06"},{"cvss_score":5.5,"headline":"Information disclosure in Microsoft Excel Viewer","id":"CVE-2018-8427","kev_date_added":null,"published":"2018-10-10"}],"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":"FIRST CVSS licence","name":"CVSS (FIRST)"}],"ssvc":{"automatable":null,"exploitation":null,"technical_impact":null},"state":"PUBLISHED","updated":"2024-08-05","vendors":["Microsoft"]},"summary":"Remote code execution via memory handling flaws in Microsoft Graphics Components affects Windows and Office products.","url":"https://insights.sbomify.com/CVE-2018-8432/"}
