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-2025-11266 in the wild and no public exploit code.\n\nAffected product: Grassroots DICOM (GDCM). 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-2025-11266/ (Markdown: https://insights.sbomify.com/CVE-2025-11266/index.md)","id":"CVE-2025-11266","markdown":"https://insights.sbomify.com/CVE-2025-11266/index.md","name":"CVE-2025-11266","record":{"aliases":["DEBIAN-CVE-2025-11266","GHSA-7qcj-ww2g-7w6j","UBUNTU-CVE-2025-11266"],"analysis":{"component_type":"library","fix_type":"patch","impacts":["denial_of_service"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"DICOM medical imaging library","requires_auth":"none","summary":"Attackers can cause a denial of service by tricking users into opening a malicious DICOM file, affecting applications using the GDCM library.","user_interaction":"required","vuln_class":"memory_corruption"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"icscert","cpe":[],"cvss":{"score":6.8,"severity":"medium","source":"cna","vector":"CVSS:4.0/AV:L/AC:L/AT:N/PR:N/UI:A/VC:L/VI:L/VA:H/SC:N/SI:N/SA:N","version":"4.0"},"cwes":[{"id":"CWE-787","name":"Out-of-bounds Write"}],"description":"An out-of-bounds write vulnerability exists in the Grassroots DICOM library (GDCM). The issue is triggered during parsing of a malformed DICOM file containing encapsulated PixelData fragments (compressed image data stored as multiple fragments). This vulnerability leads to a segmentation fault caused by an out-of-bounds memory access due to unsigned integer underflow in buffer indexing. It is exploitable via file input, simply opening a crafted malicious DICOM file is sufficient to trigger the crash, resulting in a denial-of-service condition.","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":"Grassroots DICOM (GDCM) Out-of-bounds Write","id":"CVE-2025-11266","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"memory_corruption","year":"2025"},"n_packages":0,"n_references":3,"next":{"headline":"VK All in One Expansion Unit \u003c= 9.112.1 - Authenticated (Contributor+) Stored Cross-Site Scripting","id":"CVE-2025-11267"},"packages":[],"prev":{"headline":"VK All in One Expansion Unit \u003c= 9.112.1 - Authenticated (Contributor+) Stored Cross-Site Scripting","id":"CVE-2025-11265"},"products":["DICOM (GDCM)","SimpleITK","medInria"],"published":"2025-12-12","related":[],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"class":"attribution","licence":"CWE Terms of Use","name":"CWE (MITRE)"},{"class":"attribution","licence":"FIRST CVSS licence","name":"CVSS (FIRST)"}],"ssvc":{"automatable":"no","exploitation":"none","technical_impact":"partial"},"state":"PUBLISHED","updated":"2026-01-20","vendors":["Grassroots","NumFocus","medInria"]},"summary":"Attackers can cause a denial of service by tricking users into opening a malicious DICOM file, affecting applications using the GDCM library.","url":"https://insights.sbomify.com/CVE-2025-11266/"}
