CVE-2017-17434 not yet assigned priority: Debian including 1 source packages (rsync), 5 status rows across 5 suites (bookworm, bullseye, forky, sid, trixie): resolved 5.
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.
