It can only be exploited from the same machine or local network, and only if a user opens a file or follows a link.\nExploitation: There is no known exploitation of CVE-2021-3496 in the wild and no public exploit code.\n\nAffected product: jhead. 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-2021-3496/ (Markdown: https://insights.sbomify.com/CVE-2021-3496/index.md)","id":"CVE-2021-3496","markdown":"https://insights.sbomify.com/CVE-2021-3496/index.md","name":"CVE-2021-3496","record":{"aliases":["DEBIAN-CVE-2021-3496","GHSA-rvxv-5pj2-85pq","UBUNTU-CVE-2021-3496","openSUSE-SU-2021:0594-1","openSUSE-SU-2021:0620-1"],"analysis":{"component_type":"library","fix_type":"patch","impacts":["code_execution","denial_of_service"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"JPEG EXIF tool","requires_auth":"none","summary":"A heap-based buffer overflow in jhead allows attackers to execute arbitrary code or cause denial of service via a crafted file.","user_interaction":"required","vuln_class":"memory_corruption"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"fedora","cpe":[{"product":"jhead","vendor":"jhead_project"}],"cvss":{"score":7.8,"severity":"high","source":"nvd","vector":"CVSS:3.1/AV:L/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-787","name":"Out-of-bounds Write"},{"id":"CWE-119","name":"Improper Restriction of Operations within the Bounds of a Memory Buffer"}],"description":"A heap-based buffer overflow was found in jhead in version 3.06 in Get16u() in exif.c when processing a crafted file.","ecosystems":["SUSE:Package Hub 15 SP2","openSUSE:Leap 15.2"],"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 jhead","id":"CVE-2021-3496","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"memory_corruption","year":"2021"},"n_packages":2,"n_references":3,"next":{"headline":"Use after free in gstreamer-plugins-good","id":"CVE-2021-3497"},"packages":[{"ecosystem":"SUSE:Package Hub 15 SP2","fixed":["3.00-bp152.4.3.1"],"introduced":["0"],"last_affected":[],"package":"jhead","purl":"pkg:rpm/suse/jhead\u0026distro=SUSE%20Package%20Hub%2015%20SP2","source":"openSUSE-SU-2021:0620-1"},{"ecosystem":"openSUSE:Leap 15.2","fixed":["3.00-lp152.7.3.1"],"introduced":["0"],"last_affected":[],"package":"jhead","purl":"pkg:rpm/opensuse/jhead\u0026distro=openSUSE%20Leap%2015.2","source":"openSUSE-SU-2021:0594-1"}],"prev":{"headline":"Access control flaw in Kiali","id":"CVE-2021-3495"},"products":["jhead"],"published":"2021-04-22","related":[{"cvss_score":9.8,"headline":"Memory corruption in n/a","id":"CVE-2022-28550","kev_date_added":null,"published":"2023-06-13"},{"cvss_score":7.8,"headline":"Use after free in n/a","id":"CVE-2025-44906","kev_date_added":null,"published":"2025-05-30"},{"cvss_score":7.8,"headline":"Memory corruption in n/a","id":"CVE-2021-28277","kev_date_added":null,"published":"2022-03-23"},{"cvss_score":7.8,"headline":"Memory corruption in n/a","id":"CVE-2021-28278","kev_date_added":null,"published":"2022-03-23"},{"cvss_score":7.8,"headline":"Other in n/a","id":"CVE-2018-16554","kev_date_added":null,"published":"2018-09-16"},{"cvss_score":7.8,"headline":"Integer overflow in n/a","id":"CVE-2018-17088","kev_date_added":null,"published":"2018-09-16"}],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"class":"attribution","licence":"CC BY 4.0","name":"SUSE","prefix":"openSUSE"},{"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":"2024-08-03","vendors":["n/a"]},"summary":"A heap-based buffer overflow in jhead allows attackers to execute arbitrary code or cause denial of service via a crafted file.","url":"https://insights.sbomify.com/CVE-2021-3496/"}
