Description
A denial of service issue exists where the
rdg process packet() function dispatches a PKT TYPE EXTENDED AUTH MSG without verifying the negotiated mode or authentication context. A malicious or compromised RD Gateway can send an extended-auth packet before tunnel authentication, triggering a null-pointer dereference—a condition where the software attempts to read a memory location that is null—which results in a client crash.Recommendations
Update to version 3.32.2 or later.
