Summary
gnupg, gnupg2 vulnerabilities
Details

Daniel Genkin, Lev Pachmanov, Itamar Pipman, 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-2014-3591)

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 Böck 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.
