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-2018-5268 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- opencv-contrib-python (PyPI): affected all versions; fixed in 3.4.1.15\n- opencv-contrib-python (PyPI): affected all versions; fixed in 3.4.1.15\n- opencv-contrib-python (PyPI): affected all versions; fixed in 3.4.1.15\n- opencv-python (PyPI): affected all versions; fixed in 3.4.1.15\n- opencv-python (PyPI): affected all versions; fixed in 3.4.1.15\n- opencv-python (PyPI): affected all versions; fixed in 3.4.1.15\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-2018-5268/ (Markdown: https://insights.sbomify.com/CVE-2018-5268/index.md)","id":"CVE-2018-5268","markdown":"https://insights.sbomify.com/CVE-2018-5268/index.md","name":"CVE-2018-5268","record":{"aliases":["DEBIAN-CVE-2018-5268","GHSA-9g8h-pjm4-q92p","PYSEC-2026-2814","PYSEC-2026-705","UBUNTU-CVE-2018-5268"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["code_execution","denial_of_service"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"OpenCV image library","requires_auth":"none","summary":"A heap-based buffer overflow in OpenCV's JPEG2000 decoder allows attackers to execute arbitrary code or cause denial of service via crafted images.","user_interaction":"required","vuln_class":"memory_corruption"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"debian_linux","vendor":"debian"},{"product":"opencv","vendor":"opencv"}],"cvss":{"score":5.5,"severity":"medium","source":"nvd","vector":"CVSS:3.1/AV:L/AC:L/PR:N/UI:R/S:U/C:N/I:N/A:H","version":"3.1"},"cwes":[{"id":"CWE-787","name":"Out-of-bounds Write"}],"description":"In OpenCV 3.3.1, a heap-based buffer overflow happens in cv::Jpeg2KDecoder::readComponent8u in modules/imgcodecs/src/grfmt_jpeg2000.cpp when parsing a crafted image file.","ecosystems":["PyPI"],"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":"Out-of-bounds Write in OpenCV.","id":"CVE-2018-5268","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":"PyPI","product":"debian:debian_linux","products":["debian:debian_linux"],"type":"memory_corruption","year":"2018"},"n_packages":6,"n_references":5,"next":{"headline":"Reachable Assertion in OpenCV.","id":"CVE-2018-5269"},"packages":[{"ecosystem":"PyPI","fixed":["3.4.1.15"],"introduced":["0"],"last_affected":[],"package":"opencv-contrib-python","purl":null,"source":"GHSA-9g8h-pjm4-q92p"},{"ecosystem":"PyPI","fixed":["3.4.1.15"],"introduced":["0"],"last_affected":[],"package":"opencv-contrib-python","purl":"pkg:pypi/opencv-contrib-python","source":"GHSA-9g8h-pjm4-q92p"},{"ecosystem":"PyPI","fixed":["3.4.1.15"],"introduced":["0"],"last_affected":[],"package":"opencv-contrib-python","purl":"pkg:pypi/opencv-contrib-python","source":"PYSEC-2026-705"},{"ecosystem":"PyPI","fixed":["3.4.1.15"],"introduced":["0"],"last_affected":[],"package":"opencv-python","purl":null,"source":"GHSA-9g8h-pjm4-q92p"},{"ecosystem":"PyPI","fixed":["3.4.1.15"],"introduced":["0"],"last_affected":[],"package":"opencv-python","purl":"pkg:pypi/opencv-python","source":"GHSA-9g8h-pjm4-q92p"},{"ecosystem":"PyPI","fixed":["3.4.1.15"],"introduced":["0"],"last_affected":[],"package":"opencv-python","purl":"pkg:pypi/opencv-python","source":"PYSEC-2026-2814"}],"prev":{"headline":"Auth bypass in n/a","id":"CVE-2018-5267"},"products":["n/a"],"published":"2018-01-08","related":[{"cvss_score":10,"headline":"ProFTPD Improper Access Control","id":"CVE-2015-3306","kev_date_added":"2026-10-08","published":"2015-05-18"},{"cvss_score":9.9,"headline":"RoundCube Webmail Deserialization of Untrusted Data","id":"CVE-2025-49113","kev_date_added":"2026-02-20","published":"2025-06-02"},{"cvss_score":9.8,"headline":"GNU InetUtils Argument Injection","id":"CVE-2026-24061","kev_date_added":"2026-01-26","published":"2026-01-21"},{"cvss_score":9.8,"headline":"Linux Kernel Improper Check for Unusual or Exceptional Conditions","id":"CVE-2025-39682","kev_date_added":"2026-09-18","published":"2025-09-05"},{"cvss_score":9.8,"headline":"Mozilla Firefox Use-After-Free","id":"CVE-2024-9680","kev_date_added":"2024-10-15","published":"2024-10-09"},{"cvss_score":9.8,"headline":"RARLAB UnRAR Directory Traversal","id":"CVE-2022-30333","kev_date_added":"2022-08-09","published":"2022-05-09"},{"cvss_score":9.8,"headline":"Roundcube Webmail SQL Injection","id":"CVE-2021-44026","kev_date_added":"2023-06-22","published":"2021-11-19"}],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"class":"attribution","licence":"CC BY 4.0","name":"GitHub Advisory Database","prefix":"GHSA"},{"class":"attribution","licence":"CC BY 4.0","name":"PyPA Advisory Database","prefix":"PYSEC"},{"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":"2024-08-05","vendors":["n/a"]},"summary":"A heap-based buffer overflow in OpenCV's JPEG2000 decoder allows attackers to execute arbitrary code or cause denial of service via crafted images.","url":"https://insights.sbomify.com/CVE-2018-5268/"}
