Descriptions

In ImfChromaticities.cpp routine RGBtoXYZ(), there are some division operations such as `float Z = (1 - chroma.white.x - chroma.white.y) * Y / chroma.white.y;` and `chroma.green.y * (X + Z))) / d;` but the divisor is not checked for a 0 value. A specially crafted file could trigger a divide-by-zero condition which could affect the availability of programs linked with OpenEXR.

En la rutina RGBtoXYZ() del archivo ImfChromaticities.cpp, se presentan algunas operaciones de división como "float Z = (1 - chroma.white.x - chroma.white.y) * Y / chroma.white.y;" y "chroma.green.y * (X + Z)) / d;" pero no es comprobado que el divisor tenga un valor 0. Un archivo especialmente diseñado podría desencadenar una condición de división por cero que podría afectar a la disponibilidad de los programas enlazados con OpenEXR
