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-2026-6039 in the wild and no public exploit code.\n\nAffected product: The Document Foundation LibreOffice. 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-2026-6039/ (Markdown: https://insights.sbomify.com/CVE-2026-6039/index.md)","id":"CVE-2026-6039","markdown":"https://insights.sbomify.com/CVE-2026-6039/index.md","name":"CVE-2026-6039","record":{"aliases":["DEBIAN-CVE-2026-6039","GHSA-5jvm-83q6-h5jj","UBUNTU-CVE-2026-6039"],"analysis":{"component_type":"desktop_application","fix_type":"upgrade","impacts":["code_execution","denial_of_service"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Office suite","requires_auth":"none","summary":"A heap buffer overflow in LibreOffice's DXF importer allows attackers to execute arbitrary code or cause a crash via a malicious file.","user_interaction":"required","vuln_class":"memory_corruption"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"Document Fdn.","cpe":[],"cvss":{"score":5.4,"severity":"medium","source":"cna","vector":"CVSS:4.0/AV:L/AC:L/AT:N/PR:N/UI:P/VC:L/VI:L/VA:H/SC:N/SI:N/SA:N/E:P","version":"4.0"},"cwes":[{"id":"CWE-787","name":"Out-of-bounds Write"},{"id":"CWE-197","name":"Numeric Truncation Error"}],"description":"LibreOffice can import drawings in the DXF format used by CAD software. A heap buffer overflow existed when importing a DXF polyline. The point count taken from the file was truncated to a 16-bit value when the point buffer was sized, while the full count was used to fill it, so a polyline whose point count exceeded the 16-bit range was written past the end of the buffer. In fixed versions such oversized polylines are rejected.","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":"Heap buffer overflow in DXF polyline import","id":"CVE-2026-6039","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"memory_corruption","year":"2026"},"n_packages":0,"n_references":1,"next":{"headline":"Heap use-after-free in ODF number-format blank-width parsing","id":"CVE-2026-6040"},"packages":[],"prev":{"headline":"code-projects Vehicle Showroom Management System RegisterCustomerFunction.php sql injection","id":"CVE-2026-6038"},"products":["LibreOffice"],"published":"2026-06-15","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":"2026-06-15","vendors":["The Document Foundation"]},"summary":"A heap buffer overflow in LibreOffice's DXF importer allows attackers to execute arbitrary code or cause a crash via a malicious file.","url":"https://insights.sbomify.com/CVE-2026-6039/"}
