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-2018-5201 in the wild and no public exploit code.\n\nAffected product: Hancom Office. 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-2018-5201/ (Markdown: https://insights.sbomify.com/CVE-2018-5201/index.md)","id":"CVE-2018-5201","markdown":"https://insights.sbomify.com/CVE-2018-5201/index.md","name":"CVE-2018-5201","record":{"aliases":["GHSA-g457-3qpj-v3gc"],"analysis":{"component_type":"desktop_application","fix_type":"patch","impacts":["denial_of_service"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Hancom Office","requires_auth":"none","summary":"A heap overflow in Hancom Office allows attackers to cause a program crash or denial of service via a malicious document.","user_interaction":"required","vuln_class":"memory_corruption"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"krcert","cpe":[{"product":"hancom_office_2010","vendor":"hancom"},{"product":"hancom_office_2014","vendor":"hancom"},{"product":"hancom_office_2018","vendor":"hancom"},{"product":"hancom_office_neo","vendor":"hancom"}],"cvss":{"score":5.5,"severity":"medium","source":"nvd","vector":"CVSS:3.0/AV:L/AC:L/PR:N/UI:R/S:U/C:N/I:N/A:H","version":"3.0"},"cwes":[{"id":"CWE-787","name":"Out-of-bounds Write"}],"description":"Hancom Office 2018 10.0.0.8214 and earlier, Hancom Office NEO 9.6.1.10472 and earlier, Hancom Office 2014 9.1.1.4540 and earlier, Hancom Office 2010 8.5.8.1724 and earlier versions have a heap overflow vulnerability when handling Compound File in document.
