Quick fix

PYSEC-2010-21 — pyftpdlib: upgrade to the fixed version with the command below.

pip install --upgrade 'pyftpdlib>=0.2.0'

Details

FTPServer.py in pyftpdlib before 0.2.0 does not increment the attempted_logins count for a USER command that specifies an invalid username, which makes it easier for remote attackers to obtain access via a brute-force attack.
