PYSEC-2010-7
Quick fix
PYSEC-2010-7 — pyftpdlib: upgrade to the fixed version with the command below.
pip install --upgrade 'pyftpdlib>=0.5.1'Details
Race condition in the FTPHandler class in ftpserver.py in pyftpdlib before 0.5.1 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 return value of None, a different vulnerability than CVE-2010-3494.
