It can only be exploited from the same machine or local network, with no action from the victim.\nExploitation: It is not confirmed as exploited in the wild, but public exploit code for CVE-2019-25656 exists.\n\nAffected product: R-Project R i386. 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-2019-25656/ (Markdown: https://insights.sbomify.com/CVE-2019-25656/index.md)","id":"CVE-2019-25656","markdown":"https://insights.sbomify.com/CVE-2019-25656/index.md","name":"CVE-2019-25656","record":{"aliases":["GHSA-j848-jmr8-xfgr","UBUNTU-CVE-2019-25656"],"analysis":{"component_type":"desktop_application","fix_type":"upgrade","impacts":["code_execution"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"R statistical software","requires_auth":"none","summary":"Local attackers can achieve arbitrary code execution by exploiting a buffer overflow in the R i386 GUI preferences dialog via malicious input.","user_interaction":"not_required","vuln_class":"memory_corruption"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"VulnCheck","cpe":[],"cvss":{"score":8.6,"severity":"high","source":"cna","vector":"CVSS:4.0/AV:L/AC:L/AT:N/PR:N/UI:N/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":"R i386 3.5.0 contains a local buffer overflow vulnerability in the GUI Preferences dialog that allows local attackers to trigger a structured exception handler (SEH) overwrite by supplying malicious input.
