Sorry, I was wrong. For extensions like .jpeg with a known MIME type it does not work. So, people are unlikely to be relying on this effect. http://lists.debian.org/caljhhg8dd+nv2uvgjbvrtubdna3m+o1afo0bqylyfpqkhuj...@mail.gmail.com >> But some sites accept file uploads with arbitrary names, [...] > > Don't Do That Then(TM).

To protect against that, I notice our drupal6 packages create an .htaccess file in the file uploads directory, with: > SetHandler Drupal_Security_Do_Not_Remove_See_SA_2006_006 (Advisory is at https://drupal.org/files/sa-2006-006/advisory.txt ) That also shows what a persistent problem this has been in the LAMP webserver stack for many years. I really hope FastCGI/FPM is an opportunity to put this right, among other things.
