Hi George, (Note: I'm just a user.)
Your issue sounds similar to either of these bugs: guacd, Release 1.2.0 segfaults in connection with RDP-Sessions https://issues.apache.org/jira/browse/GUACAMOLE-1203 Tolerate RDP protocol violations where possible: https://issues.apache.org/jira/browse/GUACAMOLE-1059 (this bug shows as fixed in 1.2.0. I wonder if this "fix" is causing the 1203 bug?) * Additional reference: rdpbcgr connection sequence: https://securitylab.github.com/static/09944e314cb4d4cf299530f0d9383846/179f0/image5.png https://docs.microsoft.com/en-us/openspecs/windows_protocols/ms-rdpbcgr/023f1e69-cfe8-4ee6-9ee0-7e759fb4e4ee Other rdp details: https://securitylab.github.com/research/fuzzing-sockets-FreeRDP On Wed, Jan 20, 2021 at 3:35 AM George Krajcsovits via FreeRDP-devel < freerdp-devel@lists.sourceforge.net> wrote: > Hi, > > I'm using freerdp 2.2.0 via Guacamole 1.3.0 on Ubuntu 18.04 LTS. > In my use case, first there is a TLS security connection to the server, > which then redirects to the final connection , which is using NLA. > > If I move the mouse during the redirection (or do any other input), then > NLA connection fails because the server receives INPUT PDUs during the > connection phase and aborts due to protocol violation.
