The white paper from Cisco Talos presents a case study showing how a heap overflow vulnerability can be introduced by manipulating the DICOM file format. Specifically, it focuses on the Orthanc server's image upload process, where malformed DICOM data can trigger an out-of-bounds write in heap memory. This vulnerability arises from the complexity and critical nature of DICOM parsing in medical imaging systems. The analysis covers components such as Pydicom and GDCM, which are commonly used DICOM decoders. No affected versions or patches are specified, and no active exploitation has been reported.

The impact involves potential memory corruption via heap overflow during DICOM image uploads to Orthanc servers. This could affect the stability or security of systems processing DICOM files, possibly leading to denial of service or other unintended behavior. However, the severity is assessed as low, and no active exploitation has been observed.
