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-2016-4290 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-2016-4290/ (Markdown: https://insights.sbomify.com/CVE-2016-4290/index.md)","id":"CVE-2016-4290","markdown":"https://insights.sbomify.com/CVE-2016-4290/index.md","name":"CVE-2016-4290","record":{"aliases":["GHSA-vq8v-g3rp-6fc2"],"analysis":{"component_type":"desktop_application","fix_type":"patch","impacts":["code_execution"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Hancom Office","requires_auth":"none","summary":"An integer overflow in Hancom Office allows attackers to execute arbitrary code via a malicious HShow document.","user_interaction":"required","vuln_class":"integer_overflow"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"certcc","cpe":[{"product":"hancom_office_2014","vendor":"hancom"}],"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":[{"id":"CWE-190","name":"Integer Overflow or Wraparound"}],"description":"When opening a Hangul HShow Document (.hpt) and processing a structure within the document, Hancom Office 2014 will attempt to allocate space for a block of data within the file. When calculating this length, the application will use a value from the file and add a constant to it without checking whether the addition of the constant will cause the integer to overflow which will cause the buffer to be undersized when the application tries to copy file data into it. This allows one to overwrite contiguous data in the heap which can lead to code-execution under the context of the application.","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":"Integer overflow in Hancom Office","id":"CVE-2016-4290","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"integer_overflow","year":"2016"},"n_packages":0,"n_references":2,"next":{"headline":"Integer overflow in Hancom Office","id":"CVE-2016-4291"},"packages":[],"prev":{"headline":"Memory corruption in GMER","id":"CVE-2016-4289"},"products":["Hancom Office"],"published":"2017-01-06","related":[{"cvss_score":7.8,"headline":"Memory corruption in n/a","id":"CVE-2016-4293","kev_date_added":null,"published":"2017-04-20"},{"cvss_score":7.8,"headline":"Integer overflow in Hancom Office","id":"CVE-2016-4291","kev_date_added":null,"published":"2017-01-06"},{"cvss_score":7.8,"headline":"Memory corruption in Hancom Office","id":"CVE-2016-4292","kev_date_added":null,"published":"2017-01-06"},{"cvss_score":7.8,"headline":"Memory corruption in Hancom Office","id":"CVE-2016-4294","kev_date_added":null,"published":"2017-01-06"},{"cvss_score":7.8,"headline":"Memory corruption in Hancom Office","id":"CVE-2016-4295","kev_date_added":null,"published":"2017-01-06"},{"cvss_score":7.8,"headline":"Memory corruption in Hancom Office","id":"CVE-2016-4296","kev_date_added":null,"published":"2017-01-06"}],"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":["Hancom"]},"summary":"An integer overflow in Hancom Office allows attackers to execute arbitrary code via a malicious HShow document.","url":"https://insights.sbomify.com/CVE-2016-4290/"}
