Technical description

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.

Remediation

Check the references section for vendor advisories, patches, and mitigation guidance. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
