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-2018-5269 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-2018-5269/ (Markdown: https://insights.sbomify.com/CVE-2018-5269/index.md)","id":"CVE-2018-5269","markdown":"https://insights.sbomify.com/CVE-2018-5269/index.md","name":"CVE-2018-5269","record":{"aliases":["DEBIAN-CVE-2018-5269","GHSA-89rj-5ggj-3p9p","PYSEC-2026-2812","PYSEC-2026-703","UBUNTU-CVE-2018-5269"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["denial_of_service"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"OpenCV image library","requires_auth":"none","summary":"An incorrect integer cast in OpenCV causes an assertion failure, leading to a denial of service when processing malformed images.","user_interaction":"required","vuln_class":"integer_overflow"},"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-617","name":"Reachable Assertion"}],"description":"In OpenCV 3.3.1, an assertion failure happens in cv::RBaseStream::setPos in modules/imgcodecs/src/bitstrm.cpp because of an incorrect integer cast.","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":"Reachable Assertion in OpenCV.","id":"CVE-2018-5269","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":"PyPI","product":"debian:debian_linux","products":["debian:debian_linux"],"type":"integer_overflow","year":"2018"},"n_packages":6,"n_references":5,"next":{"headline":"Denial of service in n/a","id":"CVE-2018-5270"},"packages":[{"ecosystem":"PyPI","fixed":["3.4.1.15"],"introduced":["0"],"last_affected":[],"package":"opencv-contrib-python","purl":null,"source":"GHSA-89rj-5ggj-3p9p"},{"ecosystem":"PyPI","fixed":["3.4.1.15"],"introduced":["0"],"last_affected":[],"package":"opencv-contrib-python","purl":"pkg:pypi/opencv-contrib-python","source":"GHSA-89rj-5ggj-3p9p"},{"ecosystem":"PyPI","fixed":["3.4.1.15"],"introduced":["0"],"last_affected":[],"package":"opencv-contrib-python","purl":"pkg:pypi/opencv-contrib-python","source":"PYSEC-2026-703"},{"ecosystem":"PyPI","fixed":["3.4.1.15"],"introduced":["0"],"last_affected":[],"package":"opencv-python","purl":null,"source":"GHSA-89rj-5ggj-3p9p"},{"ecosystem":"PyPI","fixed":["3.4.1.15"],"introduced":["0"],"last_affected":[],"package":"opencv-python","purl":"pkg:pypi/opencv-python","source":"GHSA-89rj-5ggj-3p9p"},{"ecosystem":"PyPI","fixed":["3.4.1.15"],"introduced":["0"],"last_affected":[],"package":"opencv-python","purl":"pkg:pypi/opencv-python","source":"PYSEC-2026-2812"}],"prev":{"headline":"Out-of-bounds Write in OpenCV.","id":"CVE-2018-5268"},"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":"An incorrect integer cast in OpenCV causes an assertion failure, leading to a denial of service when processing malformed images.","url":"https://insights.sbomify.com/CVE-2018-5269/"}
