{"schema":"threatline.record/2","record":{"id":"CVE-2026-44034","aliases":[],"summary":"Heap out-of-bounds read in DCMTK RLE decodeFrame()","details":"A heap-based out-of-bounds read in DcmRLECodecDecoder::decodeFrame() in dcmdata/libsrc/dcrleccd.cc of OFFIS DCMTK 3.7.0 allows an attacker to read up to 63 bytes of adjacent heap memory, or cause a crash, via a crafted RLE Lossless DICOM file whose pixel data fragment is shorter than the 64-byte RLE header. The function copies 64 bytes without checking the fragment length, a check that the sibling function decode() already performs. Applications that decode RLE images frame by frame (for example, through DcmPixelData::getUncompressedFrame()) are affected. The dcmdrle command-line tool uses decode() and is not affected. The issue is fixed in commit 45469f3c30037e9c7159290e4bb74cd7b3b9ef1d.","categories":["Unclassified"],"product":"DCMTK","vendor":"OFFIS","ecosystem":null,"affected_ranges":[{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-44034","source_modified_at":"2026-10-08T14:09:23.670Z","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":0.01088,"score_date":"2026-10-23"},"published_at":"2026-10-08T12:55:09.201Z","modified_at":"2026-10-08T14:09:23.670Z","provenance":[{"source":"CVE List","url":"https://www.cve.org/CVERecord?id=CVE-2026-44034","fetched_at":"2026-10-23T18:48:36.087640Z","source_modified_at":"2026-10-08T14:09:23.670Z"},{"source":"EPSS","url":"https://api.first.org/data/v1/epss?cve=CVE-2026-44034","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/1213","tags":["issue-tracking","vendor-advisory"]},{"source":"CVE List","url":"https://github.com/DCMTK/dcmtk/commit/45469f3c30037e9c7159290e4bb74cd7b3b9ef1d","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":"2026-10-08T14:09:13.036801Z"},"classification":{"method":"product-first software-layer rules","rules_version":"2.1","matched_on":null,"confidence":"unknown","reviewed":false},"change_timestamp":"2026-10-08T14:09:23.670Z","content_hash":"e55d26b97dbee088cb6f7308cb6636dcfe7dad1063ba2f0be973a1c57a9110e8"}}
