| Package | Affected versions | Patched versions |
|---|---|---|
| pyftpdlib | < 0.5.1 | 0.5.1 |
| pyftpdlib | = 0.1= 0.1.1= 0.2.0= 0.3.0= 0.4.0≤ 0.5.0 |
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.
