Subject [jira] Created: (MODPYTHON-40) FieldStorage : don't stream file uploads to memory

FieldStorage : don't stream file uploads to memory
--------------------------------------------------

         Key: MODPYTHON-40
         URL: http://issues.apache.org/jira/browse/MODPYTHON-40
     Project: mod_python
        Type: Bug
    Versions: 3.1.4    
    Reporter: Nicolas Lehuen


In mod_python.py/util.py, line 169, we stream a file upload to disk only if its Content-Disposition
header features a filename attribute. Otherwise, the file is streamed to memory, thus opening
a potential DoS attack by uploading very large files.

We should :

1) Always stream file upload to disk
2) Define a default maximum file size which could be overridable.
3) Allow for the user to specify in which directory file uploads should be made, with a default
to a temporary directory / file.
