Comment 2 Huzaifa S. Sidhpurwala 2019-02-18 06:44:43 UTC
Note:

You need to connect to a malicious or a MITM RDP server in order to trigger this flaw. The malicious RDP server can cause a controlled buffer overflow on the client, which may result in code execution. However since the flaw can only be triggered by a specially crafted RDP server, this is why it is rated as having moderate security impact.
