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-2012-4436 in the wild and no public exploit code.\n\nAffected product: n/a. 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-2012-4436/ (Markdown: https://insights.sbomify.com/CVE-2012-4436/index.md)","id":"CVE-2012-4436","markdown":"https://insights.sbomify.com/CVE-2012-4436/index.md","name":"CVE-2012-4436","record":{"aliases":["DEBIAN-CVE-2012-4436","GHSA-f5j9-5h8m-c8mw"],"analysis":{"component_type":"server_software","fix_type":"upgrade","impacts":["denial_of_service","code_execution"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"fwknop client","requires_auth":"none","summary":"Local attackers can trigger a buffer overflow in the fwknop client via crafted arguments, causing a crash or potentially executing arbitrary code.","user_interaction":"not_required","vuln_class":"memory_corruption"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"redhat","cpe":[{"product":"fwknop","vendor":"cipherdyne"}],"cvss":{"score":4.4,"severity":"medium","source":"nvd","vector":"AV:L/AC:M/Au:N/C:P/I:P/A:P","version":"2.0"},"cwes":[{"id":"CWE-119","name":"Improper Restriction of Operations within the Bounds of a Memory Buffer"}],"description":"Buffer overflow in the run_last_args function in client/fwknop.c in fwknop before 2.0.3, when processing --last, might allow local users to cause a denial of service (client crash) and possibly execute arbitrary code via many .fwknop.run arguments.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"none_known"},"has_fix":true,"headline":"Memory corruption in n/a","id":"CVE-2012-4436","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"memory_corruption","year":"2012"},"n_packages":0,"n_references":4,"next":{"headline":"Cross-site Scripting in SmartyException","id":"CVE-2012-4437"},"packages":[],"prev":{"headline":"Denial of service in n/a","id":"CVE-2012-4435"},"products":["n/a"],"published":"2012-10-22","related":[{"cvss_score":8.8,"headline":"fwknop before 2.0.3 allow remote authenticated users to cause a denial of service (server crash) or possibly execute arbitrary code.","id":"CVE-2012-4434","kev_date_added":null,"published":"2020-01-09"},{"cvss_score":4,"headline":"Denial of service in n/a","id":"CVE-2012-4435","kev_date_added":null,"published":"2012-10-22"}],"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":"2024-09-16","vendors":["n/a"]},"summary":"Local attackers can trigger a buffer overflow in the fwknop client via crafted arguments, causing a crash or potentially executing arbitrary code.","url":"https://insights.sbomify.com/CVE-2012-4436/"}
