A critical heap buffer overflow vulnerability was identified in the `Crypto_AOS_ProcessSecurity` function of CryptoLib versions 1.3.3 and prior. This vulnerability allows an attacker to trigger a Denial of Service (DoS) or potentially execute arbitrary code (RCE) by providing a maliciously crafted AOS frame with an insufficient length. The vulnerability lies in the function `Crypto_AOS_ProcessSecurity`, specifically during the processing of the Frame Error Control Field (FECF). The affected code attempts to read from the `p_ingest` buffer at indices `current_managed_parameters_struct.max_frame_size - 2` and `current_managed_parameters_struct.max_frame_size - 1` without verifying if `len_ingest` is sufficiently large. This leads to a heap buffer overflow when `len_ingest` is smaller than `max_frame_size`. As of time of publication, no known patched versions exist."},{"lang":"es","value":"CryptoLib ofrece una solución exclusivamente de software que utiliza el Protocolo de Seguridad de Enlace de Datos Espaciales CCSDS - Procedimientos Extendidos (SDLS-EP) para proteger las comunicaciones entre una nave espacial que ejecuta el Sistema de Vuelo (cFS) y una estación terrestre. Se identificó una vulnerabilidad crítica de desbordamiento del búfer de pila en la función `Crypto_AOS_ProcessSecurity` de las versiones 1.3.3 y anteriores de CryptoLib. Esta vulnerabilidad permite a un atacante activar una denegación de servicio (DoS) o, potencialmente, ejecutar código arbitrario (RCE) al proporcionar una trama AOS maliciosa con una longitud insuficiente. La vulnerabilidad reside en la función `Crypto_AOS_ProcessSecurity`, específicamente durante el procesamiento del Campo de Control de Error de Trama (FECF). El código afectado intenta leer del búfer `p_ingest` en los índices `current_managed_parameters_struct.max_frame_size - 2` y `current_managed_parameters_struct.max_frame_size - 1` sin verificar si `len_ingest` es lo suficientemente grande. Esto provoca un desbordamiento del búfer del montón cuando `len_ingest` es menor que `max_frame_size`.
