This could potentially lead to unauthorized access to protected information. **Recommendations** At the moment, there is no information about a newer version that contains a fix for this vulnerability.

This allows a remote unauthenticated attacker to disclose a file in a legitimate user's product by using previously eavesdropped cleartext information and to counterfeit a legitimate user’s system. **Recommendations** At the moment, there is no information about a newer version that contains a fix for this vulnerability.
