    {

      "value": "There are 4 places in HistogramCompare() in MagickCore/histogram.c where an integer overflow is possible during simple math calculations. This occurs in the rgb values and `count` value for a color. The patch uses casts to `ssize_t` type for these calculations, instead of `int`. This flaw could impact application reliability in the event that ImageMagick processes a crafted input file. This flaw affects ImageMagick versions prior to 7.0.9-0."

      "value": "Existen 4 ubicaciones en la funci\u00f3n HistogramCompare() en el archivo MagickCore/histogram.c, donde es posible un desbordamiento de enteros durante c\u00e1lculos matem\u00e1ticos simples. Esto ocurre en los valores rgb y en el valor \"count\" de un color. El parche usa conversiones del tipo \"ssize_t\" para estos c\u00e1lculos, en lugar de \"int\". Este fallo podr\u00eda afectar la confiabilidad de la aplicaci\u00f3n en caso de que ImageMagick procese un archivo de entrada dise\u00f1ado. Este fallo afecta a ImageMagick versiones anteriores a 7.0.9-0"
