**Name of the Vulnerable Software and Affected Versions** NASA CryptoLib versions prior to 1.3.2 **Description** The issue is related to NASA CryptoLib not checking whether the SA is in an operational state before use. This could possibly lead to a bypass of the Space Data Link Security protocol (SDLS). **Recommendations** For versions prior to 1.3.2, update to version 1.3.2 or later to resolve the issue. As a temporary workaround, consider implementing additional checks to ensure the SA is in an operational state before use.
