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.

Security readout for executives and security teams

CVE-2010-3494 is an availability bug in pyftpdlib before 0.5.2. A remote client could trigger a race condition that makes the FTP daemon stop, causing an outage rather than data theft or code execution based on the provided sources. Exposure is most likely where legacy systems run FTP services implemented with pyftpdlib versions before 0.5.2. The bundle provides no CPEs, packaged product list, or deployment prevalence. Treat this as a legacy service availability risk. Prioritize if FTP remains internet-facing or supports critical transfers; otherwise handle through normal vulnerability management and modernization planning. Mitigation focus: Inventory FTP services that use pyftpdlib.; Upgrade pyftpdlib to 0.5.2 or later where applicable.; Check vendor or distribution advisories for backported fixes..
