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-2020-28840 exists.\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-2020-28840/ (Markdown: https://insights.sbomify.com/CVE-2020-28840/index.md)","id":"CVE-2020-28840","markdown":"https://insights.sbomify.com/CVE-2020-28840/index.md","name":"CVE-2020-28840","record":{"aliases":["DEBIAN-CVE-2020-28840","GHSA-h46m-86hc-7cwf","GHSA-xh27-xwgj-gqw2","UBUNTU-CVE-2020-28840"],"analysis":{"component_type":"desktop_application","fix_type":"upgrade","impacts":["code_execution","denial_of_service"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"jhead image tool","requires_auth":"low_privilege","summary":"Local attackers can execute arbitrary code or cause denial of service via a buffer overflow in jhead.","user_interaction":"not_required","vuln_class":"memory_corruption"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"jhead","vendor":"matthiaswandel"}],"cvss":{"score":7.8,"severity":"high","source":"nvd","vector":"CVSS:3.1/AV:L/AC:L/PR:L/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 vulnerability in jpgfile.c in Matthias-Wandel jhead version 3.04, allows local attackers to execute arbitrary code and cause a denial of service (DoS).","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"weaponised"},"has_fix":true,"headline":"Memory corruption in n/a","id":"CVE-2020-28840","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"memory_corruption","year":"2020"},"n_packages":0,"n_references":4,"next":{"headline":"Denial of service in n/a","id":"CVE-2020-28841"},"packages":[],"prev":{"headline":"OpenCart Cross-Site Request Forgery (CSRF)","id":"CVE-2020-28838"},"products":["n/a"],"published":"2023-08-11","related":[],"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":"no","exploitation":"poc","technical_impact":"total"},"state":"PUBLISHED","updated":"2024-10-09","vendors":["n/a"]},"summary":"Local attackers can execute arbitrary code or cause denial of service via a buffer overflow in jhead.","url":"https://insights.sbomify.com/CVE-2020-28840/"}
