Descriptions

In ParseMetaGeometry() of MagickCore/geometry.c, image height and width calculations can lead to divide-by-zero conditions which also lead to undefined behavior. This flaw can be triggered by a crafted input file processed by ImageMagick and could impact application availability. The patch uses multiplication in addition to the function `PerceptibleReciprocal()` in order to prevent such divide-by-zero conditions. This flaw affects ImageMagick versions prior to 7.0.9-0.

En la función ParseMetaGeometry() del archivo MagickCore/geometry.c, los cálculos de altura y ancho de la imagen pueden conllevar a condiciones de división por cero que también conllevan a un comportamiento indefinido. Este fallo puede ser desencadenado por un archivo de entrada diseñado procesado por ImageMagick y podría impactar la disponibilidad de la aplicación. El parche utiliza la multiplicación aunado a la función "PerceptibleReciprocal()" a fin de impedir tales condiciones de división por cero. Este fallo afecta a ImageMagick versiones anteriores a 7.0.9-0
