Talos shows heap overflow in Orthanc PACS via crafted DICOM files
Talos' white‑paper shows how malformed DICOM files can trigger a heap overflow in Orthanc, an open‑source PACS server, by exploiting parsing bugs in libraries like pydicom and GDCM. The researchers walk through the vulnerability chain, demonstrating an out‑of‑bounds write that could lead to remote code execution.
