Freshness: upstream tracker timestamp is available; use API updated time as primary recency signal.
CVE-2017-9526 low priority: Ubuntu including 2 source packages (libgcrypt11, libgcrypt20), 18 status rows across 9 suites (artful, bionic, cosmic, disco, trusty, upstream, xenial, yakkety, zesty): DNE 8, not-affected 6, released 4.
In Libgcrypt before 1.7.7, an attacker who learns the EdDSA session key (from side-channel observation during the signing process) can easily recover the long-term secret key. 1.7.7 makes a cipher/ecc-eddsa.c change to store this session key in secure memory, to ensure that constant-time point operations are used in the MPI library.
