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.

A NULL pointer dereference in the component /libsrc/dcrleccd.cc of DCMTK v3.6.9+ DEV allows attackers to cause a Denial of Service (DoS) via a crafted DICOM file.

DCMTK v3.6.9+ DEV was discovered to contain a buffer overflow via the component /dcmimgle/diinpxt.h.
