Prior to version 1.4.3, the convert_hexstring_to_byte_array() function in the MariaDB SA interface writes decoded bytes into a caller-provided buffer without any capacity check. When importing SA fields from the database (e.g., IV, ARSN, ABM), a malformed or oversized hex string in the database can overflow the destination buffer, corrupting adjacent heap memory. This issue has been patched in version 1.4.3."},{"lang":"es","value":"CryptoLib proporciona una solución únicamente de software utilizando el Protocolo de Seguridad de Enlace de Datos Espaciales CCSDS - Procedimientos Extendidos (SDLS-EP) para asegurar las comunicaciones entre una nave espacial que ejecuta el Sistema de Vuelo central (cFS) y una estación terrestre.
