Quick fix

PYSEC-2010-24 — pyftpdlib: upgrade to the fixed version with the command below.

pip install --upgrade 'pyftpdlib>=0.2.0'

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.
