The daemon in rsync 3.1.2, and 3.1.3-development before 2017-12-03, does
not check for fnamecmp filenames in the daemon_filter_list data structure
(in the recv_files function in receiver.c) and also does not apply the
sanitize_paths protection mechanism to pathnames found in “xname follows”
strings (in the read_ndx_and_attrs function in rsync.c), which allows
remote attackers to bypass intended access restrictions.
