Descriptions

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.

En la función SetImageExtent() del archivo /MagickCore/image.c, un tamaño de profundidad de imagen incorrecto puede causar una pérdida de memoria porque el código que verifica el tamaño de profundidad de imagen apropiado no restablece el tamaño en caso de que haya un tamaño no válido. El parche restablece la profundidad a un tamaño apropiado antes de lanzar una excepción. La pérdida de memoria puede ser desencadenada por un archivo de entrada diseñado que es procesado por ImageMagick y podría causar un impacto en la confiabilidad de la aplicación, como una denegación de servicio. Este fallo afecta a ImageMagick versiones anteriores a 7.0.9-0
