Package: x2goclient
Version: 4.0.1.2
Severity: Grave

I am using ArchLinux Linux 3.12.6-1-ARCH #1 SMP PREEMPT Fri Dec 20 19:39:00 CET 2013

When "Client side printing support" is enabled, x2goclient appends an entry to ~/.ssh/authorized_keys.
Worse, these entries are not removed when exiting x2goclient.

This is a security risk, as the user did not intend to allow permanent access to that particular key,
especially when the client computer runs an OpenSSH server.

Performing chmod -w ~/.ssh/authorized_keys and then running x2goclient with client side printing gives
an error message: "Unable to write : /home/serwy/.ssh/authorized_keys". This message is generated
in void ONMainWindow::startX2goMount() at line 8867 in onmainwindow.cpp.

x2goclient shouldn't need to write to ~/.ssh/authorized_keys.

Regards,
Roger Serwy
