title: Is the application/octet-stream MIME type safe for uploading?
body: <p>We have a server side PHP script to handle file uploads from an Android app. This script identifies the mime type of AMR files as <code>application/octet-stream</code>. We have an array containing some MIME types that script uses to check whether the file is safe or not. I'm not sure whether to add <code>application/octet-stream</code> to this array or not. Is it safe? Or do we have to check this type of file more thoroughly? If yes, how?</p>
