An attacker can exploit it over the internet without logging in, and only if a user opens a file or follows a link.\nExploitation: There is no known exploitation of CVE-2012-2840 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-2012-2840/ (Markdown: https://insights.sbomify.com/CVE-2012-2840/index.md)","id":"CVE-2012-2840","markdown":"https://insights.sbomify.com/CVE-2012-2840/index.md","name":"CVE-2012-2840","record":{"aliases":["ALPINE-CVE-2012-2840","DEBIAN-CVE-2012-2840","GHSA-7r47-9m3f-8mp5"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["code_execution","denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"EXIF parsing library","requires_auth":"none","summary":"Remote attackers can cause denial of service or execute arbitrary code via crafted EXIF tags in images processed by the libexif library.","user_interaction":"required","vuln_class":"integer_overflow"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"Chrome","cpe":[{"product":"libexif","vendor":"libexif_project"}],"cvss":{"score":7.5,"severity":"high","source":"nvd","vector":"AV:N/AC:L/Au:N/C:P/I:P/A:P","version":"2.0"},"cwes":[{"id":"CWE-189","name":null}],"description":"Off-by-one error in the exif_convert_utf16_to_utf8 function in exif-entry.c in the EXIF Tag Parsing Library (aka libexif) before 0.6.21 allows remote attackers to cause a denial of service or possibly execute arbitrary code via crafted EXIF tags in an image.","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":"Integer overflow in n/a","id":"CVE-2012-2840","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"integer_overflow","year":"2012"},"n_packages":0,"n_references":7,"next":{"headline":"Integer overflow in n/a","id":"CVE-2012-2841"},"packages":[],"prev":{"headline":"Denial of service in n/a","id":"CVE-2012-2837"},"products":["n/a"],"published":"2012-07-13","related":[{"cvss_score":9.1,"headline":"Information disclosure in libexif","id":"CVE-2017-7544","kev_date_added":null,"published":"2017-09-21"},{"cvss_score":7.5,"headline":"Denial of service in libexif","id":"CVE-2018-20030","kev_date_added":null,"published":"2019-02-20"},{"cvss_score":7.5,"headline":"Memory corruption in n/a","id":"CVE-2012-2814","kev_date_added":null,"published":"2012-07-13"},{"cvss_score":7.5,"headline":"Integer overflow in n/a","id":"CVE-2012-2841","kev_date_added":null,"published":"2012-07-13"},{"cvss_score":7.4,"headline":"Integer overflow in libexif","id":"CVE-2026-32775","kev_date_added":null,"published":"2026-03-16"},{"cvss_score":6.8,"headline":"Memory corruption in n/a","id":"CVE-2009-3895","kev_date_added":null,"published":"2009-11-20"}],"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":"2024-08-06","vendors":["n/a"]},"summary":"Remote attackers can cause denial of service or execute arbitrary code via crafted EXIF tags in images processed by the libexif library.","url":"https://insights.sbomify.com/CVE-2012-2840/"}
