It can only be exploited from the same machine or local network, and only if a user opens a file or follows a link."},"fix_prompt":"Check this codebase for CVE-2023-38127 and fix it if it is affected.\n\nWhat it is: CVE-2023-38127 is a high-severity vulnerability in Ichitaro 2023, published on 19 Oct 2023. 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: It is not confirmed as exploited in the wild, but public exploit code for CVE-2023-38127 exists.\n\nAffected product: Ichitaro 2023. 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-2023-38127/ (Markdown: https://insights.sbomify.com/CVE-2023-38127/index.md)","id":"CVE-2023-38127","markdown":"https://insights.sbomify.com/CVE-2023-38127/index.md","name":"CVE-2023-38127","record":{"aliases":["GHSA-f9vm-fr8w-hm2v"],"analysis":{"component_type":"desktop_application","fix_type":"patch","impacts":["code_execution"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Ichitaro word processor","requires_auth":"none","summary":"An integer overflow in Ichitaro's parser allows attackers to execute arbitrary code via a malicious document.","user_interaction":"required","vuln_class":"integer_overflow"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"talos","cpe":[{"product":"easy_postcard_max","vendor":"justsystems"},{"product":"ichitaro_2021","vendor":"justsystems"},{"product":"ichitaro_2022","vendor":"justsystems"},{"product":"ichitaro_2023","vendor":"justsystems"},{"product":"ichitaro_government_10","vendor":"justsystems"},{"product":"ichitaro_government_8","vendor":"justsystems"},{"product":"ichitaro_government_9","vendor":"justsystems"},{"product":"ichitaro_pro_3","vendor":"justsystems"},{"product":"ichitaro_pro_4","vendor":"justsystems"},{"product":"ichitaro_pro_5","vendor":"justsystems"},{"product":"just_government_3","vendor":"justsystems"},{"product":"just_government_4","vendor":"justsystems"},{"product":"just_government_5","vendor":"justsystems"},{"product":"just_office_3","vendor":"justsystems"},{"product":"just_office_4","vendor":"justsystems"},{"product":"just_office_5","vendor":"justsystems"},{"product":"just_police_3","vendor":"justsystems"},{"product":"just_police_4","vendor":"justsystems"},{"product":"just_police_5","vendor":"justsystems"}],"cvss":{"score":7.8,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:L/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-190","name":"Integer Overflow or Wraparound"}],"description":"An integer overflow exists in the \"HyperLinkFrame\" stream parser of Ichitaro 2023 1.0.1.59372.
