{"schema":"threatline.record/2","record":{"id":"CVE-2026-44038","aliases":[],"summary":"Global buffer out-of-bounds read in DCMTK JPEG Huffman decoding","details":"A global out-of-bounds read in the Huffman decoder of the bundled IJG JPEG libraries (dcmjpeg/libijg8, libijg12 and libijg16) of OFFIS DCMTK 3.7.0 allows an attacker to read memory beyond the extend_test[] and extend_offset[] tables, causing incorrectly decoded pixel data or a crash, via a DICOM file with a crafted JPEG stream whose Huffman table defines a difference category above 15. Huffman symbol values are not range-checked unless DCMTK is built with DCMTK_ENABLE_STRICT_HUFFMAN_TABLE_CHECK, which is disabled by default. dcmdjpeg and any application that decompresses JPEG DICOM images with DCMTK are affected. The issue is fixed in commit d6ae1bc8d5b9ae9c7300013c8c85cc2ea0fd8cf5.","categories":["Unclassified"],"product":"DCMTK","vendor":"OFFIS","ecosystem":null,"affected_ranges":[{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-44038","source_modified_at":"2026-10-08T14:08:19.615Z","fetched_at":"2026-10-23T18:48:36.087640Z","product":"DCMTK","vendor":"OFFIS","versions":[{"version":"3.7.0","status":"affected"}],"defaultStatus":"unknown"}],"fixed_versions":[],"cvss":4.8,"severity":"Medium","kev":{"listed":false},"epss":{"probability":0.00107,"percentile":0.01089,"score_date":"2026-10-23"},"published_at":"2026-10-08T12:55:13.689Z","modified_at":"2026-10-08T14:08:19.615Z","provenance":[{"source":"CVE List","url":"https://www.cve.org/CVERecord?id=CVE-2026-44038","fetched_at":"2026-10-23T18:48:36.087640Z","source_modified_at":"2026-10-08T14:08:19.615Z"},{"source":"EPSS","url":"https://api.first.org/data/v1/epss?cve=CVE-2026-44038","fetched_at":"2026-10-23T18:42:43.628194Z","source_modified_at":"2026-10-23"}],"sources":["CVE List","EPSS"],"references":[{"source":"CVE List","url":"https://support.dcmtk.org/redmine/issues/1221","tags":["issue-tracking","vendor-advisory"]},{"source":"CVE List","url":"https://github.com/DCMTK/dcmtk/commit/d6ae1bc8d5b9ae9c7300013c8c85cc2ea0fd8cf5","tags":["patch"]}],"locations":[],"motoko_assessment":{"status":"requires_architecture_review","automatic_remediation":false},"cve_state":"PUBLISHED","cvss_source":"CVE List","ssvc":{"exploitation":"none","automatable":"no","technical_impact":"partial","assessed_at":"2026-10-08T14:08:11.020411Z"},"classification":{"method":"product-first software-layer rules","rules_version":"2.1","matched_on":null,"confidence":"unknown","reviewed":false},"change_timestamp":"2026-10-08T14:08:19.615Z","content_hash":"1a72ac3649d4ec1a6d1929b65599bec9aea5be97b1cc4eb85006364cac40fc6b"}}
