This update addresses an arbitrary file copy vulnerability in mod_copy in ProFTPD, which allowed for remote code execution and information disclosure without authentication due to not honoring <Limit>
constraints.
Upstream bug: http://bugs.proftpd.org/show_bug.cgi?id=4372
Note that Tenable Network Security has extracted the preceding description block directly from the Fedora update system website.
Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.
