Fedora Update Notification
FEDORA-2020-876b1f664e
2020-02-27 17:26:04.898880
——————————————————————————–

Name : proftpd
Product : Fedora 31
Version : 1.3.6c
Release : 1.fc31
URL : http://www.proftpd.org/
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
visibility.

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 update, to the current upstream stable release version, is a cumulative
bug-fix release including a security fix for a use-after-free vulnerability
(CVE-2020-9273): successful exploitation of this vulnerability could allow a
remote attacker to execute arbitrary code on the affected system.
