Fedora Update Notification
FEDORA-2026-871243b391
2026-05-21 00:54:04.884676+00:00
--------------------------------------------------------------------------------

Name        : proftpd
Product     : Fedora 44
Version     : 1.3.9a
Release     : 2.fc44
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 contains an updated mod_wrap2_sql that addresses a potential SQL
injection issue when connected to from a client with a maliciously-constructed
reverse DNS record (CVE-2026-44331). Note that mod_wrap2_sql is not enabled by
default and the issue can only happen if UseReverseDNS is enabled, which is also
off by default.
--------------------------------------------------------------------------------
ChangeLog:

* Mon May 11 2026 Paul Howarth <paul@city-fan.org> - 1.3.9a-2
- Additional escaping for avoidance of SQL injection issues with %{note:...}
  and %{env:...}; these are on top of the existing fix for CVE-2026-42167 in
  1.3.9a
- Fix for SQL Injection in mod_wrap2_sql via reverse DNS hostname
  (CVE-2026-44331, rhbz#2466899, https://github.com/proftpd/proftpd/issues/2057)
