CVE-2026-44038 1 Offis 1 Dcmtk 2026-10-08 4.4 Medium
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.
CVE-2026-44037 1 Offis 1 Dcmtk 2026-10-08 5.5 Medium
Uncontrolled mutual recursion between DcmJSONReader::parseDataSet(), DcmJSONReader::parseElement() and DcmJSONReader::parseSequence() in dcmdata/libsrc/dcjsonrd.cc of OFFIS DCMTK 3.7.0 allows an attacker to cause a denial of service (stack exhaustion and process crash) via a crafted DICOM JSON document with deeply nested sequence (SQ) values. The json2dcm tool and any service that converts untrusted DICOM JSON (for example, DICOMweb payloads) with this reader are affected. The issue is fixed in commit cf955e64c35a1e07ba10698f639d5dcdec53b9d7.
CVE-2026-44036 1 Offis 1 Dcmtk 2026-10-08 5.5 Medium
Uncontrolled mutual recursion between DcmXMLParseHelper::parseDataSet() and DcmXMLParseHelper::parseSequence() in the XML-to-DICOM converter (dcmdata/libdcxml/xml2dcm.cc) of OFFIS DCMTK 3.7.0 allows an attacker to cause a denial of service (stack exhaustion and process crash) via a crafted XML file with deeply nested sequence and item elements. The xml2dcm tool and any service that converts untrusted XML to DICOM with this code are affected. The issue is fixed in commit 87f256d73e30656a822bf7d76d1cf1d9bb693954.
CVE-2026-44035 1 Offis 1 Dcmtk 2026-10-08 5.5 Medium
Uncontrolled recursion in DcmDicomDir::moveRecordToTree() in dcmdata/libsrc/dcdicdir.cc of OFFIS DCMTK 3.7.0 allows an attacker to cause a denial of service (stack exhaustion and process crash) via a crafted DICOMDIR file with a deeply chained sequence of directory records linked through the Offset of Referenced Lower-Level Directory Entity attribute. Any application that opens the DICOMDIR is affected, including dcmgpdir and media viewers built on DCMTK. The issue is fixed in commit ca761f7f3dcaaddaa95be87cf5d736138d7c3a9f.
CVE-2026-44034 1 Offis 1 Dcmtk 2026-10-08 4.4 Medium
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.
CVE-2026-44033 1 Offis 1 Dcmtk 2026-10-08 5.5 Medium
Uncontrolled recursion in XMLNode::ParseXMLElement() and XMLNode::emptyTheNode() in the bundled XML parser (ofstd/libsrc/ofxml.cc) of OFFIS DCMTK 3.7.0 allows an attacker to cause a denial of service (stack exhaustion and process crash) via a crafted XML document with deeply nested elements. The parser is reachable through dcmencap when encapsulating a CDA document, and through any application that calls OFXMLParser::parseFile() or OFXMLParser::parseString() on untrusted input. The issue is fixed in commit d12e350e687530eb41e2b0c860aff4d8c04e5941.
CVE-2026-44031 1 Offis 1 Dcmtk 2026-10-08 7.5 High
Uncontrolled recursion in DcmSequenceOfItems::read() and DcmItem::read() in the dcmdata library of OFFIS DCMTK 3.7.0 allows a remote, unauthenticated attacker to cause a denial of service (stack exhaustion and process crash) via a DICOM dataset containing deeply nested sequences (SQ elements). The dataset can be sent in a C-STORE request to storescp, dcmrecv, dcmqrscp, or any other DICOM service built on DCMTK, because the received dataset is parsed before any authentication takes place. Local tools such as dcmdump also crash when opening such a file. The issue is fixed in commit 885ff0f10372bd589b5f44cea974f28a3964cb0f, which adds a configurable sequence nesting depth limit (default 64).
CVE-2026-97059 1 Offis 1 Dcmtk 2026-09-30 8.2 High
DCMTK through 3.7.0 contains a heap over-read vulnerability in ConcatenationLoader that copies pixel data frames without validating the PixelData buffer length against the declared NumberOfFrames. Attackers can craft malicious DICOM instances declaring more frames than the buffer contains to trigger heap over-reads that crash the application or leak adjacent heap memory.
