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-2021-28276 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-2021-28276/ (Markdown: https://insights.sbomify.com/CVE-2021-28276/index.md)","id":"CVE-2021-28276","markdown":"https://insights.sbomify.com/CVE-2021-28276/index.md","name":"CVE-2021-28276","record":{"aliases":["DEBIAN-CVE-2021-28276","GHSA-hfvw-936h-fq94","UBUNTU-CVE-2021-28276"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"jhead image tool","requires_auth":"none","summary":"An attacker can cause a denial of service in jhead via a wild address read in the ProcessCanonMakerNoteDir function.","user_interaction":"not_required","vuln_class":"denial_of_service"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"jhead","vendor":"jhead_project"}],"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":[],"description":"A Denial of Service vulnerability exists in jhead 3.04 and 3.05 via a wild address read in the ProcessCanonMakerNoteDir function in makernote.c.","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":"Denial of service in n/a","id":"CVE-2021-28276","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"denial_of_service","year":"2021"},"n_packages":0,"n_references":2,"next":{"headline":"Memory corruption in n/a","id":"CVE-2021-28277"},"packages":[],"prev":{"headline":"Denial of service in n/a","id":"CVE-2021-28275"},"products":["n/a"],"published":"2022-03-23","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":"Memory corruption in jhead","id":"CVE-2021-3496","kev_date_added":null,"published":"2021-04-22"},{"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":"US public information, NVD API terms","name":"NVD"},{"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":"An attacker can cause a denial of service in jhead via a wild address read in the ProcessCanonMakerNoteDir function.","url":"https://insights.sbomify.com/CVE-2021-28276/"}
