Summary: pyftpdlib vulnerable to allocation of resources without limits

Details: The ftp_STOU function in FTPServer.py in pyftpdlib before 0.2.0 does not limit the number of attempts to discover a unique filename, which might allow remote authenticated users to cause a denial of service via a STOU command.
