Описание
An out-of-bounds read vulnerability exists in the DecodeLookupTable function within DicomImageDecoder.cpp. The lookup-table decoding logic used for PALETTE COLOR images does not validate pixel indices against the lookup table size. Crafted images containing indices larger than the palette size cause the decoder to read beyond allocated lookup table memory and expose heap contents in the output image.
