OpenEXR Out-Of-Memory via Unbounded File Header Values

The OpenEXR file format defines many information about the final image inside of the file header, such as the size of data/display window. The application trusts the value of dataWindow size provided in the header of the input file, and performs computations based on this value. This may result in unintended behaviors, such as excessively large number of iterations and/or huge memory allocations.
