Fedora Update Notification
2019-10-29 01:07:34.725333

Name : proftpd
Product : Fedora 30
Version : 1.3.6b
Release : 1.fc30
Summary : Flexible, stable and highly-configurable FTP server
Description :
ProFTPD is an enhanced FTP server with a focus toward simplicity, security,
and ease of configuration. It features a very Apache-like configuration
syntax, and a highly customizable server infrastructure, including support for
multiple ‘virtual’ FTP servers, anonymous FTP, and permission-based directory

This package defaults to the standalone behavior of ProFTPD, but all the
needed scripts to have it run by systemd instead are included.

Update Information:

This is a cumulative bug-fix update from upstream, including a fix for a pre-
authentication remote denial of service issue.
