An attacker can exploit it over the internet without logging in, and only if a user opens a file or follows a link.\nExploitation: It is not confirmed as exploited in the wild, but public exploit code for CVE-2026-12805 exists.\n\nAffected product: OFFIS DCMTK. 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-2026-12805/ (Markdown: https://insights.sbomify.com/CVE-2026-12805/index.md)","id":"CVE-2026-12805","markdown":"https://insights.sbomify.com/CVE-2026-12805/index.md","name":"CVE-2026-12805","record":{"aliases":["DEBIAN-CVE-2026-12805","GHSA-35pp-gpq2-4898","UBUNTU-CVE-2026-12805"],"analysis":{"component_type":"library","fix_type":"patch","impacts":["code_execution","denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"DCMTK medical imaging library","requires_auth":"none","summary":"A heap-based buffer overflow in DCMTK's XML parser allows remote attackers to execute arbitrary code or cause denial of service via crafted files.","user_interaction":"required","vuln_class":"memory_corruption"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"VulDB","cpe":[],"cvss":{"score":5.3,"severity":"medium","source":"cna","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:P/VC:L/VI:L/VA:L/SC:N/SI:N/SA:N/E:P","version":"4.0"},"cwes":[{"id":"CWE-122","name":"Heap-based Buffer Overflow"},{"id":"CWE-119","name":"Improper Restriction of Operations within the Bounds of a Memory Buffer"}],"description":"A flaw has been found in OFFIS DCMTK up to 3.7.0. The affected element is the function XMLNode::parseFile in the library ofstd/libsrc/ofxml.cc. Executing a manipulation can lead to heap-based buffer overflow. The attack may be performed from remote. The exploit has been published and may be used. This patch is called 1d4b3815c0987840a983160bfc671fef63a3105b. It is best practice to apply a patch to resolve this issue. The vendor was contacted early, responded in a very professional manner and quickly released a fixed version of the affected product.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"weaponised"},"has_fix":true,"headline":"OFFIS DCMTK ofxml.cc parseFile heap-based overflow","id":"CVE-2026-12805","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"memory_corruption","year":"2026"},"n_packages":0,"n_references":8,"next":{"headline":"Edimax BR-6478AC V2 POST Request formWlSiteSurvey buffer overflow","id":"CVE-2026-12806"},"packages":[],"prev":{"headline":"lemonldap-ng SAML Common Domain Cookie Endpoint CDC.pm redirect","id":"CVE-2026-12804"},"products":["DCMTK"],"published":"2026-06-21","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":"poc","technical_impact":"partial"},"state":"PUBLISHED","updated":"2026-06-23","vendors":["OFFIS"]},"summary":"A heap-based buffer overflow in DCMTK's XML parser allows remote attackers to execute arbitrary code or cause denial of service via crafted files.","url":"https://insights.sbomify.com/CVE-2026-12805/"}
