Until an official fix is available, avoid processing untrusted DICOM files or apply application-level controls to limit exposure.
Description
DCMTK versions up to 3.7.0 have a heap over-read vulnerability in the ConcatenationLoader component. This occurs when pixel data frames are copied without validating the PixelData buffer length against the declared NumberOfFrames. Maliciously crafted DICOM files can trigger heap over-reads, potentially causing application crashes or leaking adjacent heap memory.
