Freshness: upstream tracker timestamp is available; use API updated time as primary recency signal.
CVE-2017-15906 low priority: Ubuntu including 1 source packages (openssh), 12 status rows across 12 suites (artful, bionic, cosmic, disco, eoan, focal, groovy, hirsute, trusty, upstream, xenial, zesty): released 11, ignored 1.
The process_open function in sftp-server.c in OpenSSH before 7.6 does not properly prevent write operations in readonly mode, which allows attackers to create zero-length files.
