Here is the ciritical code:

        if (AcquireImageColormap(image,image->colors,exception) == MagickFalse) //line 649
            ThrowReaderException(ResourceLimitError,"MemoryAllocationFailed");  //forget to free pixel_info

It can be solved by this:

        if (AcquireImageColormap(image,image->colors,exception) == MagickFalse)
          {
            pixel_info=RelinquishVirtualMemory(pixel_info);
            ThrowReaderException(ResourceLimitError,"MemoryAllocationFailed");
          }
