An attacker can exploit it over the internet without logging in, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2020-8036 in the wild and no public exploit code.\n\nAffected product: Tcpdump Tcpdump. 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-2020-8036/ (Markdown: https://insights.sbomify.com/CVE-2020-8036/index.md)","id":"CVE-2020-8036","markdown":"https://insights.sbomify.com/CVE-2020-8036/index.md","name":"CVE-2020-8036","record":{"aliases":["GHSA-ff33-26cm-5cp4"],"analysis":{"component_type":"server_software","fix_type":"patch","impacts":["denial_of_service","code_execution"],"network_reachable":"yes","non_default_config":false,"product_category":"Network packet analyzer","requires_auth":"none","summary":"An out-of-bounds read in the SOME/IP dissector allows attackers to cause a crash or potentially execute code via crafted packets.","user_interaction":"not_required","vuln_class":"memory_corruption"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"Tcpdump","cpe":[{"product":"tcpdump","vendor":"tcpdump"}],"cvss":{"score":7.5,"severity":"high","source":"nvd","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H","version":"3.1"},"cwes":[{"id":"CWE-125","name":"Out-of-bounds Read"}],"description":"The tok2strbuf() function in tcpdump 4.10.0-PRE-GIT was used by the SOME/IP dissector in an unsafe way.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":"2026-06-17","github_poc":1,"max_poc_stars":0,"metasploit":0,"nuclei":0,"refs":[{"date":"2026-06-17T16:32:49Z","kind":"github_poc","ref":"https://github.com/yan5ui/ENV-CVE-2020-8036","stars":0,"title":"Aritifacts of docker env of CVE-2020-8036"}],"tier":"poc_unverified"},"has_fix":false,"headline":"str2tokbuf used incorrectly by print-someip.c","id":"CVE-2020-8036","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"tcpdump:tcpdump","products":["tcpdump:tcpdump"],"type":"memory_corruption","year":"2020"},"n_packages":0,"n_references":1,"next":{"headline":"ppp decapsulator can be convinced to allocate a large amount of memory","id":"CVE-2020-8037"},"packages":[],"prev":{"headline":"Cross-site scripting in n/a","id":"CVE-2020-8035"},"products":["tcpdump"],"published":"2020-11-04","related":[{"cvss_score":9.8,"headline":"tcpdump before 4.9.3 mishandles the printing of SMB data (issue 1 of 2).","id":"CVE-2018-10103","kev_date_added":null,"published":"2019-10-03"},{"cvss_score":9.8,"headline":"Denial of service in n/a","id":"CVE-2018-10105","kev_date_added":null,"published":"2019-10-03"},{"cvss_score":9.8,"headline":"Memory corruption in n/a","id":"CVE-2017-12893","kev_date_added":null,"published":"2017-09-14"},{"cvss_score":9.8,"headline":"Memory corruption in n/a","id":"CVE-2017-12894","kev_date_added":null,"published":"2017-09-14"},{"cvss_score":9.8,"headline":"Memory corruption in n/a","id":"CVE-2017-12895","kev_date_added":null,"published":"2017-09-14"},{"cvss_score":9.8,"headline":"Memory corruption in n/a","id":"CVE-2017-12897","kev_date_added":null,"published":"2017-09-14"},{"cvss_score":9.8,"headline":"Memory corruption in n/a","id":"CVE-2017-12898","kev_date_added":null,"published":"2017-09-14"}],"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)"},{"class":"open","licence":"CC0","name":"PoC-in-GitHub"}],"ssvc":{"automatable":null,"exploitation":null,"technical_impact":null},"state":"PUBLISHED","updated":"2024-09-16","vendors":["The TCPdump Group"]},"summary":"An out-of-bounds read in the SOME/IP dissector allows attackers to cause a crash or potentially execute code via crafted packets.","url":"https://insights.sbomify.com/CVE-2020-8036/"}
