Freshness: upstream tracker timestamp is available; use API updated time as primary recency signal.
CVE-2017-17433 medium priority: Ubuntu including 1 source packages (rsync), 5 status rows across 5 suites (artful, trusty, upstream, xenial, zesty): released 4, needs-triage 1.
The recv_files function in receiver.c in the daemon in rsync 3.1.2, and 3.1.3-development before 2017-12-03, proceeds with certain file metadata updates before checking for a filename in the daemon_filter_list data structure, which allows remote attackers to bypass intended access restrictions.
