             Summary: Console codes crashing SSH
                 Key: GUACAMOLE-681
             Project: Guacamole
          Issue Type: Bug
          Components: SSH
    Affects Versions: 0.9.14
         Environment: Newest docker versions of guacd and guacamole, running on 
Unraid. Client is connecting from Chromium on Arch Linux.
            Reporter: Patrick Collins

Based on 
issue, it seems Guacamole is supposed to work with Linux console codes.

I'm getting reliable crashes when printing certain console codes in a Guacamole 
SSH session; notably ones printed by .bashrc in [some 

When printed directly on the device, (whether on a tty or a terminal emulator,) 
the codes work.

When printed in Guacamole, they immediately crash the session; prompting 

This command is enough to crash the session:
echo 1b5d343b0a | xxd -r -p{code}
(It converts some hex to 'ESC []4;' and prints it.)


Apologies if the priority of this issue is inappropriate; I based it off the 
"crashes" criterion; but I'm not certain to what extent the program has to 
crash to qualify.
