This may allow an attacker to brute force the application\u0027s session keys.\n\nRelease 9.46 fixes the issue by providing high quality randomness, even in absence of CryptX.\n\nUsers should be aware that the update does not replace previously generated weak secrets.  A secret generated with the previous version MUST be replaced to ensure the updated version is using a strong secret."
