Freshness: upstream tracker timestamp is available; use API updated time as primary recency signal.
CVE-2016-6313 high priority: Ubuntu including 4 source packages (gnupg, gnupg2, libgcrypt11, libgcrypt20), 40 status rows across 10 suites (artful, bionic, cosmic, disco, precise, trusty, upstream, xenial, yakkety, zesty): DNE 16, released 15, not-affected 8, needs-triage 1.
The mixing functions in the random number generator in Libgcrypt before 1.5.6, 1.6.x before 1.6.6, and 1.7.x before 1.7.3 and GnuPG before 1.4.21 make it easier for attackers to obtain the values of 160 bits by leveraging knowledge of the previous 4640 bits.
