Descriptions

A floating point math calculation in ScaleAnyToQuantum() of /MagickCore/quantum-private.h could lead to undefined behavior in the form of a value outside the range of type unsigned long long. The flaw could be triggered by a crafted input file under certain conditions when it is processed by ImageMagick. Red Hat Product Security marked this as Low because although it could potentially lead to an impact to application availability, no specific impact was shown in this case. This flaw affects ImageMagick versions prior to 7.0.8-68.

Un cálculo matemático de punto flotante en la función ScaleAnyToQuantum() del archivo /MagickCore/quantum-private.h, podría conducir a un comportamiento indefinido en forma de un valor fuera del rango de tipo unsigned long long. El fallo podría ser desencadenado por un archivo de entrada diseñado bajo determinadas condiciones cuando es procesado por ImageMagick. Red Hat Product Security marcó esto como Bajo porque, aunque podría potencialmente conllevar a un impacto en la disponibilidad de la aplicación, no fue mostrado un impacto específico en este caso. Este fallo afecta a ImageMagick versiones anteriores a 7.0.8-68
