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-2019-25679 and fix it if it is affected.\n\nWhat it is: CVE-2019-25679 is a high-severity memory corruption vulnerability in RealTerm: Serial Terminal, published on 5 Apr 2026. 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-2019-25679 exists.\n\nAffected product: RealTerm: Serial Terminal. 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-2019-25679/ (Markdown: https://insights.sbomify.com/CVE-2019-25679/index.md)","id":"CVE-2019-25679","markdown":"https://insights.sbomify.com/CVE-2019-25679/index.md","name":"CVE-2019-25679","record":{"aliases":["GHSA-6g5p-8cx2-hpcp"],"analysis":{"component_type":"desktop_application","fix_type":"no_fix_stated","impacts":["code_execution"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Serial Terminal","requires_auth":"none","summary":"Local attackers can execute arbitrary code via a buffer overflow in the Echo Port tab of RealTerm Serial Terminal.","user_interaction":"required","vuln_class":"memory_corruption"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"VulnCheck","cpe":[{"product":"realterm","vendor":"crun"}],"cvss":{"score":8.5,"severity":"high","source":"cna","vector":"CVSS:4.0/AV:L/AC:L/AT:N/PR:N/UI:P/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N","version":"4.0"},"cwes":[{"id":"CWE-787","name":"Out-of-bounds Write"}],"description":"RealTerm Serial Terminal 2.0.0.70 contains a structured exception handling (SEH) buffer overflow vulnerability in the Echo Port tab that allows local attackers to execute arbitrary code by supplying a malicious payload.
