NASA CryptoLib before 1.3.2 does not check the OTAR crypto function returned status, potentially leading to spacecraft hijacking.
NASA CryptoLib before 1.3.2 does not check whether the SA is in an operational state before use, possibly leading to a bypass of the Space Data Link Security protocol (SDLS).
NASA CryptoLib before 1.3.2 uses Extended Procedures that are a Work in Progress (not intended for use during flight), potentially leading to a keystream oracle.
In NASA CryptoLib before 1.3.2, the key state is not checked before use, potentially leading to spacecraft hijacking.
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 CryptoTCApplySecurity 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 tfpayloadlen, which is then interpreted as a large unsigned value, leading to a heap buffer overflow in a memcpy call.
