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.
