Freshness: upstream tracker timestamp is available; use API updated time as primary recency signal.
CVE-2016-2178 low priority: Ubuntu including 2 source packages (openssl, openssl098), 22 status rows across 11 suites (artful, bionic, cosmic, disco, precise, trusty, upstream, wily, xenial, yakkety, zesty): released 10, DNE 9, ignored 2, needs-triage 1.
The dsa_sign_setup function in crypto/dsa/dsa_ossl.c in OpenSSL through 1.0.2h does not properly ensure the use of constant-time operations, which makes it easier for local users to discover a DSA private key via a timing side-channel attack.
