Quick fix

PYSEC-2010-6 — pyftpdlib: upgrade to the fixed version with the command below.

pip install --upgrade 'pyftpdlib>=0.5.0'

Details

The ftp_QUIT function in ftpserver.py in pyftpdlib before 0.5.0 allows remote authenticated users to cause a denial of service (file descriptor exhaustion and daemon outage) by sending a QUIT command during a disallowed data-transfer attempt.
