DICOM, Pydicom, GDCM, and Orthanc: A technical tour of what really happens in the heap
A white paper examines heap overflow vulnerabilities in DICOM (Digital Imaging and Communications in Medicine) parsing libraries and medical imaging systems. The research demonstrates how malformed DICOM files can trigger out-of-bounds writes in Orthanc servers during image uploads, highlighting risks in Picture Archiving and Communication Systems (PACS) that automatically ingest network-received files.
Why it matters: Medical imaging infrastructure faces direct exploitation risk from malformed DICOM files; assess your PACS decoder implementations and update affected libraries immediately.
