Descriptions

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.

Existen 4 ubicaciones en la función HistogramCompare() en el archivo MagickCore/histogram.c, donde es posible un desbordamiento de enteros durante cálculos matemáticos 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 cálculos, en lugar de "int". Este fallo podría afectar la confiabilidad de la aplicación en caso de que ImageMagick procese un archivo de entrada diseñado. Este fallo afecta a ImageMagick versiones anteriores a 7.0.9-0
