You can provide feedback for this update here: https://bodhi.fedoraproject.org/updates/FEDORA-EPEL-2017-b9db4ff3ec The AllowChrootSymlinks directive was introduced in proftpd version 1.3.5. The version of proftpd shipped in EPEL-6 is 1.3.3g, which therefore does not support this directive; it is effectively the same as "AllowChrootSymlinks yes" in current proftpd versions (which is the default). I currently do not intend to issue an update for EPEL-6 for this issue; users of proftpd from EPEL-6 should take care to ensure that there are no directory elements between the root directory and their users' home directories that could be renamed/overwritten by non-root local users, either symbolic links or real directories. These would present a general security issue anyway, not just for proftpd.
