9.3 (Critical) - CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N
Summary
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. In 1.3.3 and earlier, a heap buffer overflow vulnerability persists in the Crypto_TC_ApplySecurity function due to an incomplete validation check on the fl (frame length) field. Although CVE-2025-29912 addressed an underflow issue involving fl, the patch fails to fully prevent unsafe calculations. As a result, an attacker can still craft malicious frames that cause a negative tf_payload_len, which is then interpreted as a large unsigned value, leading to a heap buffer overflow in a memcpy call.

En la versión 1.3.3 y anteriores, persiste una vulnerabilidad de desbordamiento del búfer de pila en la función Crypto_TC_ApplySecurity debido a una comprobación de validación incompleta en el campo fl (longitud de la trama). Aunque CVE-2025-29912 solucionó un problema de desbordamiento por debajo de la capacidad de fl, el parche no previene completamente los cálculos inseguros. Como resultado, un atacante aún puede manipular tramas maliciosas que provoquen un valor negativo en tf_payload_len, que se interpreta como un valor grande sin signo, lo que provoca un desbordamiento del búfer de pila en una llamada a memcpy.",
