Descriptions

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.

GnuPG 1.4.x, y 2.1.x trata un subpaquete de flags clave con todos los bits a 0 (sin uso permitido) como si tuviera todos los bits establecidos (todo uso permitido) lo que permitiría a atacantes remotos evadir mecanismos de protección criptográfica intencionada mediante el aprovechamiento de la subclave.
