  "summary" : "ImageMagick has Heap Out-of-Bounds Read in DCM Decoder (ReadDCMImage)",
  "details" : "A heap out-of-bounds read vulnerability exists in the `coders/dcm.c` module. When processing DICOM files with a specific configuration, the decoder loop incorrectly reads bytes per iteration. This causes the function to read past the end of the allocated buffer, potentially leading to a Denial of Service (crash) or Information Disclosure (leaking heap memory into the image).",
