Freshness: upstream tracker timestamp is available; use API updated time as primary recency signal.
CVE-2016-2146 medium priority: Ubuntu including 1 source packages (libapache2-mod-auth-mellon), 11 status rows across 11 suites (artful, bionic, cosmic, disco, precise, trusty, upstream, wily, xenial, yakkety, zesty): not-affected 7, DNE 2, ignored 1, released 1.
The am_read_post_data function in mod_auth_mellon before 0.11.1 does not limit the amount of data read, which allows remote attackers to cause a denial of service (worker process crash, web server deadlock, or memory consumption) via a large amount of POST data.
