When uploading files using the Media backend module, the post-processing step rotate tries to figure out the actual extension of the image by reading it from the EXIF metadata if the needed PHP function is available.
It turns out that the function exif_read_data is affected by a known bug and ends up throwing a PHP warning and raising an exception in my case. This prevents the post-processing stage rotate to use the fallback orientation and counts as an error regarding the file upload.
