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-2017-2789 in the wild and no public exploit code.\n\nAffected product: JustSystems Ichitaro. 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-2017-2789/ (Markdown: https://insights.sbomify.com/CVE-2017-2789/index.md)","id":"CVE-2017-2789","markdown":"https://insights.sbomify.com/CVE-2017-2789/index.md","name":"CVE-2017-2789","record":{"aliases":["GHSA-74fv-pcxw-cvhx"],"analysis":{"component_type":"desktop_application","fix_type":"patch","impacts":["code_execution"],"network_reachable":"yes","non_default_config":false,"product_category":"Office suite","requires_auth":"none","summary":"A heap-based buffer overflow in JustSystems Ichitaro Office allows attackers to execute arbitrary code via a crafted document.","user_interaction":"required","vuln_class":"memory_corruption"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"talos","cpe":[{"product":"ichitaro","vendor":"justsystems"}],"cvss":{"score":8.8,"severity":"high","source":"cna","vector":"CVSS:3.0/AV:N/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H","version":"3.0"},"cwes":[{"id":"CWE-119","name":"Improper Restriction of Operations within the Bounds of a Memory Buffer"}],"description":"When copying filedata into a buffer, JustSystems Ichitaro Office 2016 Trial will calculate two values to determine how much data to copy from the document. If both of these values are larger than the size of the buffer, the application will choose the smaller of the two and trust it to copy data from the file. This value is larger than the buffer size, which leads to a heap-based buffer overflow. This overflow corrupts an offset in the heap used in pointer arithmetic for writing data and 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":"Memory corruption in Ichitaro","id":"CVE-2017-2789","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"memory_corruption","year":"2017"},"n_packages":0,"n_references":2,"next":{"headline":"Memory corruption in Ichitaro","id":"CVE-2017-2790"},"packages":[],"prev":{"headline":"Memory corruption in PopUp Printer Client","id":"CVE-2017-2788"},"products":["Ichitaro"],"published":"2017-02-24","related":[{"cvss_score":10,"headline":"Other in n/a","id":"CVE-2014-7247","kev_date_added":null,"published":"2014-11-26"},{"cvss_score":10,"headline":"Code injection in n/a","id":"CVE-2013-3644","kev_date_added":null,"published":"2013-06-18"},{"cvss_score":9.3,"headline":"Code injection in n/a","id":"CVE-2013-5990","kev_date_added":null,"published":"2013-11-13"},{"cvss_score":9.3,"headline":"Memory corruption in n/a","id":"CVE-2012-0269","kev_date_added":null,"published":"2012-04-27"},{"cvss_score":9.3,"headline":"Memory corruption in n/a","id":"CVE-2011-1331","kev_date_added":null,"published":"2011-07-18"},{"cvss_score":9.3,"headline":"Code injection in n/a","id":"CVE-2010-3915","kev_date_added":null,"published":"2010-11-05"},{"cvss_score":9.3,"headline":"Other in n/a","id":"CVE-2010-3916","kev_date_added":null,"published":"2010-11-05"}],"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":"2024-08-05","vendors":["JustSystems"]},"summary":"A heap-based buffer overflow in JustSystems Ichitaro Office allows attackers to execute arbitrary code via a crafted document.","url":"https://insights.sbomify.com/CVE-2017-2789/"}
