Daniel Genkin, Adi Shamir, and Eran Tromer discovered that GnuPG was
susceptible to an attack via physical side channels. A local attacker could
use this attack to possibly recover private keys. (CVE-2015-0837)

Hanno Bock discovered that GnuPG incorrectly handled certain malformed
keyrings. If a user or automated system were tricked into opening a
malformed keyring, a remote attacker could use this issue to cause GnuPG to
crash, resulting in a denial of service, or possibly execute arbitrary
code. (CVE-2015-1606, CVE-2015-1607)

In addition, this update improves GnuPG security by validating that the
keys returned by keyservers match those requested.");
