"A change introduced in libssh 0.6.3-4+deb8u4 (which got released as
DLA 2038-1) has broken x2goclient's way of scp'ing session setup files
from client to server, resulting in an error message shown in a GUI
error dialog box during session startup (and session resuming).

For Debian 8 'Jessie', this problem has been fixed in x2goclient
version 4.0.3.1-4+deb8u1.

We recommend that you upgrade your x2goclient packages.

NOTE: Tenable Network Security has extracted the preceding description
block directly from the DLA security advisory. Tenable has attempted
to automatically clean and format it as much as possible without
introducing additional issues."
