Description

DCMTK through 3.7.0 contains a heap over-read vulnerability in ConcatenationLoader that copies pixel data frames without validating the PixelData buffer length against the declared NumberOfFrames. Attackers can craft malicious DICOM instances declaring more frames than the buffer contains to trigger heap over-reads that crash the application or leak adjacent heap memory.
