"value": "in SetImageExtent() of /MagickCore/image.c, an incorrect image depth size can cause a memory leak because the code which checks for the proper image depth size does not reset the size in the event there is an invalid size. The patch resets the depth to a proper size before throwing an exception. The memory leak can be triggered by a crafted input file that is processed by ImageMagick and could cause an impact to application reliability, such as denial of service. This flaw affects ImageMagick versions prior to 7.0.9-0."

"value": "En la funci\u00f3n SetImageExtent() del archivo /MagickCore/image.c, un tama\u00f1o de profundidad de imagen incorrecto puede causar una p\u00e9rdida de memoria porque el c\u00f3digo que verifica el tama\u00f1o de profundidad de imagen apropiado no restablece el tama\u00f1o en caso de que haya un tama\u00f1o no v\u00e1lido. El parche restablece la profundidad a un tama\u00f1o apropiado antes de lanzar una excepci\u00f3n. La p\u00e9rdida de memoria puede ser desencadenada por un archivo de entrada dise\u00f1ado que es procesado por ImageMagick y podr\u00eda causar un impacto en la confiabilidad de la aplicaci\u00f3n, como una denegaci\u00f3n de servicio. Este fallo afecta a ImageMagick versiones anteriores a 7.0.9-0"
