{"id":"DEBIAN-CVE-2026-44034","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.","modified":"2026-10-09T11:00:08.067612091Z","published":"2026-10-08T13:17:17.347Z","upstream":["CVE-2026-44034"],"references":[{"type":"ADVISORY","url":"https://security-tracker.debian.org/tracker/CVE-2026-44034"}],"affected":[{"package":{"name":"dcmtk","ecosystem":"Debian:12","purl":"pkg:deb/debian/dcmtk?arch=source&distro=bookworm"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["3.6.7-11","3.6.7-12","3.6.7-13","3.6.7-14","3.6.7-15","3.6.7-8","3.6.7-9","3.6.7-9.1","3.6.7-9~deb12u1","3.6.7-9~deb12u2","3.6.7-9~deb12u3","3.6.7-9~deb12u4","3.6.8-1","3.6.8-2","3.6.8-3","3.6.8-4","3.6.8-5","3.6.8-6","3.6.8-7","3.6.8~git20221024.b8950f9-1","3.6.8~git20221024.b8950f9-2","3.6.8~git20221024.b8950f9-3","3.6.8~git20231027.1549d8c-1","3.6.8~git20231027.1549d8c-2","3.6.9-1","3.6.9-2","3.6.9-3","3.6.9-4","3.6.9-5","3.6.9-6","3.7.0+really3.6.9-1","3.7.0+really3.7.0-0+exp1","3.7.0+really3.7.0-1","3.7.0+really3.7.0-2","3.7.0+really3.7.0-3","3.7.0+really3.7.0-4","3.7.0+really3.7.0-5","3.7.0+really3.7.0-6","3.7.0+really3.7.0-7","3.7.0-1"],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/debian-osv/debian-cve-osv/DEBIAN-CVE-2026-44034.json"}},{"package":{"name":"dcmtk","ecosystem":"Debian:13","purl":"pkg:deb/debian/dcmtk?arch=source&distro=trixie"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["3.6.9-5","3.6.9-5+deb13u1","3.6.9-5+deb13u2","3.6.9-5+deb13u3","3.6.9-6","3.7.0+really3.6.9-1","3.7.0+really3.7.0-0+exp1","3.7.0+really3.7.0-1","3.7.0+really3.7.0-2","3.7.0+really3.7.0-3","3.7.0+really3.7.0-4","3.7.0+really3.7.0-5","3.7.0+really3.7.0-6","3.7.0+really3.7.0-7","3.7.0-1"],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/debian-osv/debian-cve-osv/DEBIAN-CVE-2026-44034.json"}},{"package":{"name":"dcmtk","ecosystem":"Debian:14","purl":"pkg:deb/debian/dcmtk?arch=source&distro=forky"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["3.6.9-5","3.6.9-6","3.7.0+really3.6.9-1","3.7.0+really3.7.0-0+exp1","3.7.0+really3.7.0-1","3.7.0+really3.7.0-2","3.7.0+really3.7.0-3","3.7.0+really3.7.0-4","3.7.0+really3.7.0-5","3.7.0+really3.7.0-6","3.7.0+really3.7.0-7","3.7.0-1"],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/debian-osv/debian-cve-osv/DEBIAN-CVE-2026-44034.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V4","score":"CVSS:4.0/AV:L/AC:L/AT:N/PR:N/UI:P/VC:L/VI:N/VA:L/SC:N/SI:N/SA:N/E:X/CR:X/IR:X/AR:X/MAV:X/MAC:X/MAT:X/MPR:X/MUI:X/MVC:X/MVI:X/MVA:X/MSC:X/MSI:X/MSA:X/S:X/AU:X/R:X/V:X/RE:X/U:X"}]}
