It can only be exploited from the same machine or local network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2014-8271 in the wild and no public exploit code.\n\nAffected product: Tianocore EDK2. 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-2014-8271/ (Markdown: https://insights.sbomify.com/CVE-2014-8271/index.md)","id":"CVE-2014-8271","markdown":"https://insights.sbomify.com/CVE-2014-8271/index.md","name":"CVE-2014-8271","record":{"aliases":["GHSA-cf3p-hhrw-pr9m"],"analysis":{"component_type":"hardware_firmware","fix_type":"patch","impacts":["privilege_escalation"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"UEFI firmware","requires_auth":"none","summary":"A buffer overflow in Tianocore EDK2 allows physically proximate attackers to gain privileges via a long variable name.","user_interaction":"not_required","vuln_class":"memory_corruption"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"certcc","cpe":[{"product":"edk2","vendor":"tianocore"}],"cvss":{"score":6.8,"severity":"medium","source":"nvd","vector":"CVSS:3.1/AV:P/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-120","name":"Buffer Copy without Checking Size of Input"}],"description":"Buffer overflow in the Reclaim function in Tianocore EDK2 before SVN 16280 allows physically proximate attackers to gain privileges via a long variable name.","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 EDK2","id":"CVE-2014-8271","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"memory_corruption","year":"2014"},"n_packages":0,"n_references":2,"next":{"headline":"Auth bypass in n/a","id":"CVE-2014-8272"},"packages":[],"prev":{"headline":"Privilege escalation in n/a","id":"CVE-2014-8270"},"products":["EDK2"],"published":"2020-02-06","related":[{"cvss_score":8.3,"headline":"Buffer Overflow in EDK II Network Package","id":"CVE-2023-45230","kev_date_added":null,"published":"2024-01-16"},{"cvss_score":8.3,"headline":"Buffer Overflow in EDK II Network Package","id":"CVE-2023-45234","kev_date_added":null,"published":"2024-01-16"},{"cvss_score":8.3,"headline":"Buffer Overflow in EDK II Network Package","id":"CVE-2023-45235","kev_date_added":null,"published":"2024-01-16"},{"cvss_score":7.8,"headline":"Denial of service in EDK II","id":"CVE-2021-28210","kev_date_added":null,"published":"2021-06-11"},{"cvss_score":7.8,"headline":"Null dereference in Tianocore EDK2","id":"CVE-2019-14584","kev_date_added":null,"published":"2021-06-03"},{"cvss_score":7.8,"headline":"Privilege escalation in Tianocore","id":"CVE-2017-5731","kev_date_added":null,"published":"2019-10-28"},{"cvss_score":7.5,"headline":"Infinite loop in EDK II Network Package","id":"CVE-2023-45232","kev_date_added":null,"published":"2024-01-16"}],"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":"2024-08-06","vendors":["Tianocore"]},"summary":"A buffer overflow in Tianocore EDK2 allows physically proximate attackers to gain privileges via a long variable name.","url":"https://insights.sbomify.com/CVE-2014-8271/"}
