Freshness: upstream tracker timestamp is available; use API updated time as primary recency signal.
CVE-2015-3185 medium priority: Ubuntu including 1 source packages (apache2), 5 status rows across 5 suites (precise, trusty, upstream, utopic, vivid): released 3, ignored 1, not-affected 1.
The ap_some_auth_required function in server/request.c in the Apache HTTP Server 2.4.x before 2.4.14 does not consider that a Require directive may be associated with an authorization setting rather than an authentication setting, which allows remote attackers to bypass intended access restrictions in opportunistic circumstances by leveraging the presence of a module that relies on the 2.2 API behavior.
