Bugzilla: 1010137: CVE-2013-4351 gnupg: treats no-usage-permitted keys as all-usages-permitted


The MITRE CVE dictionary describes this issue as:

GnuPG 1.4.x, 2.0.x, and 2.1.x treats a key flags subpacket with all bits cleared (no usage permitted) as if it has all bits set (all usage permitted), which might allow remote attackers to bypass intended cryptographic protection mechanisms by leveraging the subkey.
