OpenPGP has three passwords: Admin PIN, Reset Code, and User PIN. The Reset Code is used to reset the User PIN, but it is disabled by default. A flaw in the implementation of OpenPGP sets the Reset Code to a known value upon initialization. If the retry counter for the Reset Code is set to non-zero without changing the Reset Code, this known value can be used to reset the User PIN. To set the retry counters, the Admin PIN is required."}, {"lang": "es", "value": "Se detect\u00f3 un problema de administraci\u00f3n de PIN en los dispositivos Yubico YubiKey versiones 5 5.2.0 hasta 5.2.6. OpenPGP tiene tres contrase\u00f1as: el PIN de administrador, el C\u00f3digo de Restablecimiento y el PIN de usuario. El c\u00f3digo de restablecimiento se usa para restablecer el PIN de usuario, pero est\u00e1 deshabilitado por defecto. Un fallo en la implementaci\u00f3n de OpenPGP establece el c\u00f3digo de restablecimiento en un valor conocido tras la inicializaci\u00f3n. Si el contador de reintentos para el C\u00f3digo de Reinicio se establece en un valor distinto de cero sin cambiar el C\u00f3digo de Reinicio, este valor conocido se puede usar para reiniciar el PIN del usuario.
