| Package | Affected versions | Patched versions |
|---|---|---|
| pyftpdlib | < 0.5.2 | 0.5.2 |
| pyftpdlib | = 0.1= 0.1.1= 0.2.0= 0.3.0= 0.4.0= 0.5.0≤ 0.5.1 |
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 getpeername function having an ENOTCONN error, a different vulnerability than CVE-2010-3494.
