An attacker can exploit it over the internet without logging in, and only if a user opens a file or follows a link."},"fix_prompt":"Check this codebase for CVE-2020-6418 and fix it if it is affected.\n\nWhat it is: CVE-2020-6418 is a high-severity memory corruption vulnerability in Debian Debian Linux, published on 27 Feb 2020. An attacker can exploit it over the internet without logging in, and only if a user opens a file or follows a link.\nExploitation: Yes. Attackers have exploited CVE-2020-6418 in the wild since at least 3 Nov 2021.\n\nAffected product: Debian Debian Linux. 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-2020-6418/ (Markdown: https://insights.sbomify.com/CVE-2020-6418/index.md)","id":"CVE-2020-6418","markdown":"https://insights.sbomify.com/CVE-2020-6418/index.md","name":"CVE-2020-6418","record":{"aliases":["DEBIAN-CVE-2020-6418","GHSA-495j-4jmx-mgrx","UBUNTU-CVE-2020-6418"],"analysis":{"component_type":"browser","fix_type":"upgrade","impacts":["code_execution"],"network_reachable":"yes","non_default_config":false,"product_category":"Google Chrome","requires_auth":"none","summary":"A remote attacker can exploit heap corruption via a crafted HTML page due to type confusion in V8, potentially executing arbitrary code.","user_interaction":"required","vuln_class":"memory_corruption"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"Chrome","cpe":[{"product":"debian_linux","vendor":"debian"},{"product":"fedora","vendor":"fedoraproject"},{"product":"chrome","vendor":"google"},{"product":"enterprise_linux_desktop","vendor":"redhat"},{"product":"enterprise_linux_server","vendor":"redhat"},{"product":"enterprise_linux_workstation","vendor":"redhat"}],"cvss":{"score":8.8,"severity":"high","source":"cisa-adp","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-843","name":"Access of Resource Using Incompatible Type"}],"description":"Type confusion in V8 in Google Chrome prior to 80.0.3987.122 allowed a remote attacker to potentially exploit heap corruption via a crafted HTML page.","ecosystems":[],"exploits":{"exploitdb":1,"first_seen":"2020-02-19","github_poc":4,"max_poc_stars":3,"metasploit":1,"nuclei":0,"refs":[{"date":"2020-06-13T07:32:24Z","kind":"github_poc","ref":"https://github.com/Goyotan/CVE-2020-6418-PoC","stars":3,"title":"for 供養"},{"date":"2022-02-19T20:00:04Z","kind":"github_poc","ref":"https://github.com/ulexec/ChromeSHELFLoader","stars":3,"title":"An exploit for CVE-2020-6418 implementing a SHELF Loader.
