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-2017-18231 in the wild and no public exploit code.\n\nAffected product: Debian Debian Linux. 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-2017-18231/ (Markdown: https://insights.sbomify.com/CVE-2017-18231/index.md)","id":"CVE-2017-18231","markdown":"https://insights.sbomify.com/CVE-2017-18231/index.md","name":"CVE-2017-18231","record":{"aliases":["DEBIAN-CVE-2017-18231","GHSA-v3qf-q4vv-2q93","UBUNTU-CVE-2017-18231"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"GraphicsMagick library","requires_auth":"none","summary":"Attackers can cause a denial of service in GraphicsMagick by providing a crafted Enhanced Metafile that triggers a NULL pointer dereference.","user_interaction":"required","vuln_class":"null_dereference"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"debian_linux","vendor":"debian"},{"product":"graphicsmagick","vendor":"graphicsmagick"}],"cvss":{"score":6.5,"severity":"medium","source":"nvd","vector":"CVSS:3.0/AV:N/AC:L/PR:N/UI:R/S:U/C:N/I:N/A:H","version":"3.0"},"cwes":[{"id":"CWE-476","name":"NULL Pointer Dereference"}],"description":"An issue was discovered in GraphicsMagick 1.3.26.
