"value": "CryptoLib provides a software-only solution using the CCSDS Space Data Link Security Protocol - Extended Procedures (SDLS-EP) to secure communications between a spacecraft running the core Flight System (cFS) and a ground station. A critical heap buffer overflow vulnerability was identified in the `Crypto_TC_Prep_AAD` 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 telecommand (TC) frame that causes an unsigned integer underflow. The vulnerability lies in the function `Crypto_TC_Prep_AAD`, specifically during the computation of `tc_mac_start_index`. The affected code incorrectly calculates the MAC start index without ensuring it remains within the bounds of the `ingest` buffer. When `tc_mac_start_index` underflows due to an incorrect length calculation, the function attempts to access an out-of-bounds memory location, leading to a segmentation fault. The vulnerability is still present in the repository as of commit `d3cc420ace96d02a5b7e83d88cbd2e48010d5723`."

"value": "CryptoLib ofrece una soluci\u00f3n 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 estaci\u00f3n terrestre. Se identific\u00f3 una vulnerabilidad cr\u00edtica de desbordamiento del b\u00fafer de pila en la funci\u00f3n `Crypto_TC_Prep_AAD` de las versiones 1.3.3 y anteriores de CryptoLib. Esta vulnerabilidad permite a un atacante desencadenar una denegaci\u00f3n de servicio (DoS) o potencialmente ejecutar c\u00f3digo arbitrario (RCE) al proporcionar una trama de telecomando (TC) maliciosa que causa un desbordamiento por debajo de un entero sin signo. La vulnerabilidad reside en la funci\u00f3n `Crypto_TC_Prep_AAD`, espec\u00edficamente durante el c\u00e1lculo de `tc_mac_start_index`. El c\u00f3digo afectado calcula incorrectamente el \u00edndice de inicio MAC sin garantizar que permanezca dentro de los l\u00edmites del b\u00fafer de ingesta. Cuando `tc_mac_start_index` presenta un desbordamiento por debajo de lo permitido debido a un c\u00e1lculo de longitud incorrecto, la funci\u00f3n intenta acceder a una ubicaci\u00f3n de memoria fuera de los l\u00edmites, lo que provoca un fallo de segmentaci\u00f3n. La vulnerabilidad persiste en el repositorio a partir del commit `d3cc420ace96d02a5b7e83d88cbd2e48010d5723`."
