Description

An integer overflow issue was discovered in ImageMagick&#39;s ExportIndexQuantum() function in MagickCore/quantum-export.c. Function calls to GetPixelIndex() could result in values outside the range of representable for the &#39;unsigned char&#39;. When ImageMagick processes a crafted pdf file, this could lead to an undefined behaviour or a crash.
