Summary
[none]

A heap buffer overflow vulnerability exists during the decoding of PALETTE COLOR DICOM images. Pixel length validation uses 32-bit multiplication for width and height calculations. If these values overflow, the validation check incorrectly succeeds, allowing the decoder to read and write to memory beyond allocated buffers.
