Freshness: upstream tracker timestamp is available; use API updated time as primary recency signal.
CVE-2016-1232 medium priority: Ubuntu including 1 source packages (prosody), 8 status rows across 8 suites (precise, trusty, upstream, vivid, wily, xenial, yakkety, zesty): released 4, not-affected 3, ignored 1.
The mod_dialback module in Prosody before 0.9.9 does not properly generate random values for the secret token for server-to-server dialback authentication, which makes it easier for attackers to spoof servers via a brute force attack.
