| | | | | | | | | | sys.getwindowsversion() (GH-25500) The sys module uses the kernel32.dll version number, which can vary from the "actual" Windows version. Since the best option for getting the version is WMI (which is expensive), we switch back to launching cmd.exe (which is also expensive, but a lot less code on our part). sys.getwindowsversion() is not updated to avoid launching executables from that module.

| | | | | | | | | | | | | | | | | | bpo-43285: Make ftplib not trust the PASV response. The IPv4 address value returned from the server in response to the PASV command should not be trusted. This prevents a malicious FTP server from using the response to probe IPv4 address and port combinations on the client network. Instead of using the returned address, we use the IP address we're already connected to. This is the strategy other ftp clients adopted, and matches the only strategy available for the modern IPv6 EPSV command where the server response must return a port number and nothing else. For the rare user who _wants_ this ugly behavior, set a `trust_server_pasv_ipv4_address` attribute on your `ftplib.FTP` instance to True..
