A stack-based buffer overflow vulnerability has been identified in Orthanc DICOM Server versions through 1.12.10. The issue arises in the DCMTK Parser component, specifically within the DcmItem::read function of the file FromDcmtkBridge.cpp. The vulnerability can be exploited locally by uploading a DICOM file containing deeply nested sequences, which leads to a stack overflow and crashes the Orthanc process. This vulnerability is particularly severe in clinical environments where Orthanc is used for patient imaging.
Users are advised to update to Orthanc version 1.12.11 or later, where this vulnerability has been fixed. The official Orthanc release notes can be consulted for update instructions.
