on <security@freebsd.org>, and subsequently in FreeBSD's cvs repository
as libexec/ftpd/ftpd.c rev 1.133:
The FTP daemon was vulnerable to a DoS where an attacker could bind()
up port 20 for an extended period of time and thus lock out all other
users from establishing PORT data connections. Don't hold on to the
bind() while we loop around waiting to see if we can make our
connection.
Bump version to 20030122.
