Freshness: upstream tracker timestamp is available; use API updated time as primary recency signal.
CVE-2016-7444 low priority: Ubuntu including 2 source packages (gnutls26, gnutls28), 20 status rows across 10 suites (artful, bionic, cosmic, disco, precise, trusty, upstream, xenial, yakkety, zesty): not-affected 10, DNE 8, released 2.
The gnutls_ocsp_resp_check_crt function in lib/x509/ocsp.c in GnuTLS before 3.4.15 and 3.5.x before 3.5.4 does not verify the serial length of an OCSP response, which might allow remote attackers to bypass an intended certificate validation mechanism via vectors involving trailing bytes left by gnutls_malloc.
