Details
Daniel Kahn Gillmor discovered that GnuPG treated keys with empty usage
flags as being valid for all usages. (CVE-2013-4351)

messages. If a user or automated system were tricked into processing a
specially-crafted message, GnuPG could consume resources, resulting in a
denial of service. (CVE-2013-4402)
