An integer overflow issue was discovered in ImageMagick’s
ExportIndexQuantum() function in MagickCore/quantum-export.c. Function
calls to GetPixelIndex() could result in values outside the range of
representable for the ‘unsigned char’. When ImageMagick processes a crafted
pdf file, this could lead to an undefined behaviour or a crash.
