Quick fix
PYSEC-2010-11 — pyftpdlib: upgrade to the fixed version with the command below.
pip install --upgrade 'pyftpdlib>=0.5.2'Details
Race condition in the FTPHandler class in ftpserver.py in pyftpdlib before 0.5.2 allows remote attackers to cause a denial of service (daemon outage) by establishing and then immediately closing a TCP connection, leading to the accept function having an unexpected value of None for the address, or an ECONNABORTED, EAGAIN, or EWOULDBLOCK error, a related issue to CVE-2010-3492.
