Name : proftpd
Product : Fedora 30
Version : 1.3.6b
Release : 2.fc30
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 addresses a number of bugs affecting processing of CRLs in mod_tls,
including possible null pointer dereferences and missing some checks. Thanks to
Lionel Debroux for reporting them.
