"value": "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."

"value": "En la funci\u00f3n ParseMetaGeometry() del archivo MagickCore/geometry.c, los c\u00e1lculos de altura y ancho de la imagen pueden conllevar a condiciones de divisi\u00f3n por cero que tambi\u00e9n conllevan a un comportamiento indefinido. Este fallo puede ser desencadenado por un archivo de entrada dise\u00f1ado procesado por ImageMagick y podr\u00eda impactar la disponibilidad de la aplicaci\u00f3n. El parche utiliza la multiplicaci\u00f3n aunado a la funci\u00f3n \"PerceptibleReciprocal()\" a fin de impedir tales condiciones de divisi\u00f3n por cero. Este fallo afecta a ImageMagick versiones anteriores a 7.0.9-0"
