Jann Horn reported that there is a possible race condition in the handling of the MKD/XMKD FTP commands, when the UserOwner directive is involved, and the attacker is on the same physical machine as a running proftpd. This race applies to mod_sftp and the handling of the MKDIR SFTP request as well.
Note that using the DefaultRoot directive to restrict sessions mitigates this attack, since the symlinks created by the local attacker will point outside of the chroot(2) area within the FTP session, and thus the ownership change will fail. The default configuration in EPEL applies the DefaultRoot directive to all users except "adm".
