Freshness: upstream tracker timestamp is available; use API updated time as primary recency signal.
CVE-2014-3591 low priority: Ubuntu including 3 source packages (gnupg, libgcrypt11, libgcrypt20), 15 status rows across 5 suites (lucid, precise, trusty, upstream, utopic): released 12, DNE 2, needed 1.
Libgcrypt before 1.6.3 and GnuPG before 1.4.19 does not implement ciphertext blinding for Elgamal decryption, which allows physically proximate attackers to obtain the server's private key by determining factors using crafted ciphertext and the fluctuations in the electromagnetic field during multiplication.
