      "value": "Several memory vulnerabilities were identified within the OpenSC packages, particularly in the card enrollment process using pkcs15-init when a user or administrator enrolls cards. To take advantage of these flaws, an attacker must have physical access to the computer system and employ a custom-crafted USB device or smart card to manipulate responses to APDUs. This manipulation can potentially allow \r\ncompromise key generation, certificate loading, and other card management operations during enrollment."

Para aprovechar estas fallas, un atacante debe tener acceso f\u00edsico al sistema inform\u00e1tico y emplear un dispositivo USB o una tarjeta inteligente hechos a medida para manipular las respuestas a las APDU. Esta manipulaci\u00f3n puede permitir potencialmente comprometer la generaci\u00f3n de claves, la carga de certificados y otras operaciones de administraci\u00f3n de tarjetas durante la inscripci\u00f3n."
