Prior to version 1.4.3, the Crypto_Config_Add_Gvcid_Managed_Parameters function only checks whether gvcid_counter > GVCID_MAN_PARAM_SIZE. As a result, it allows up to the 251st entry, which causes a write past the end of the array, overwriting gvcid_counter located immediately after gvcid_managed_parameters_array[250]. This leads to an out-of-bounds write, and the overwritten gvcid_counter may become an arbitrary value, potentially affecting the parameter lookup/registration logic that relies on it. 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 ejecutando el Sistema de Vuelo central (cFS) y una estación terrestre.
