"Vadim Melihow reported a critical issue with proftpd installations
that use the mod_copy module's SITE CPFR/SITE CPTO commands; mod_copy
allows these commands to be used by *unauthenticated clients*

Upstream report: http://bugs.proftpd.org/show_bug.cgi?id=4169

This update contains a backported fix for this issue.

Note that mod_copy is not loaded/enabled by default in the Fedora
package.

Note that Tenable Network Security has extracted the preceding
description block directly from the Fedora security advisory. Tenable
has attempted to automatically clean and format it as much as possible
without introducing additional issues."
