X2Go Client (4.1.2.0) released

Dear all

The X2Go project is proud to announce a new release of the X2Go component ,,x2goclient''.

New gains of this version of ,,x2goclient'' are:

o SSH interaction fix for GSSAPI/Kerberos authentication o new bundled VcXsrv version o GPG agent changes o LXQt support (icons and menu entry) o SSH authentication fix (password previously read from command line, making it look like the client would hang on Linux, even though it did not) o removed X2Go Browser Plugin - farewell o try harder to start the integrated X.Org Server on Windows, avoiding race conditions, goes hand-in-hand with... o new --xserver-start-limit command line parameter, denoting the number of X.Org Server startup tries on Windows (defaults to 3) o bundle further modified OpenSSH Cygwin binary and ignore host and user private key permissions - folder sharing and client-side printing fix for Windows 10+ o updated translations

The X2Go project thanks Martti Pitkänen, Sébastien Ducoulombier and Robert Parts for their valuable input and submitted work.

*** NOTE *** Binary builds for the Windows platform will likely be a bit delayed. The links do not point to this release yet. If you want to update your Windows client, please wait for the official release announcement for X2Go Client for Windows.

Binary builds for OS X 10.9 will likely be a bit delayed. The link does not point to this release yet. If you want to update your OS X 10.9 client, please wait for the official release announcement for X2Go Client for OS X 10.9. *** NOTE ***

X2Go Component: x2goclient Version: 4.1.2.0 Status: RELEASE Timestamp: 1529699429 Date: Fri, 22 Jun 2018 22:30:29 +0200 Fixes these bug report(s): 1156 1258 1263 Changes: x2goclient (4.1.2.0) RELEASED; urgency=medium . [ Mike DePaulo ]

• New upstream version (4.1.2.0):
  • src/sshmasterconnection.cpp: Do not attempt to perform Interaction with SSH Server (e.g. for changing expired password) when using GSSAPI/Kerberos because the interaction code does not support it yet. Fixes: #1258
  • Windows: Update PuTTY from 0.68 to 0.70, which fixes PuTTY vulns vuln-indirect-dll-hijack-2 & vuln-indirect-dll-hijack-3. Note that x2goclient was only ever affected if the permissions on the installation folder were changed to give users write access, or if x2goclient was copied/extracted to a folder where users could write.
  • Windows: Update Win32 OpenSSL from 1.0.2k to 1.0.2n Fixes several CVEs
  • Windows: Upgrade bundled VcXsrv from 1.17.0.0-3 (X2Go/Arctica Build) to 1.20.0.0 (upstream build)
    • Fixes https://github.com/ArcticaProject/nx-libs/issues/600
    • Incompatible with XP & Vista
    • Unmodified except for strip-nondeterminism being run on .gz files . [ Oleksandr Shneyder ]
• New upstream version (4.1.2.0):
  • don't start gpg agent for PGP card authentication. Use system agent instead.
  • change search string for pcsc_scan.
  • destroy unused SSH sessions for LDAP authentication. . [ Mihai Moldovan ]
• New upstream version (4.1.2.0):
  • misc: update version to 4.1.2.0.
  • res/img/svg: add new lxqt.svg icon file (really helix.svg).
  • res/img/icons/*x*: add new rasterized lxqt.png files in different sizes.
  • res/qresources.qrc: add new lxqt files.
  • src/{onmainwindow.cpp,session{button,widget}.{cpp,h}}: add support for LXQt. Fixes: #1263.
  • src/sshmasterconnection.cpp: stop libssh/OpenSSL from querying for a passphrase if started with a controlling terminal.
  • x2goclient.pro: remove plugin references.
  • misc: change http:// to https:// where appropriate, but in actual code and translation files for now.
  • Makefile: remove plugin references.
  • Makefile: remove x2goclient_*.qm files in clean rule.
  • x2gobrowserplugin-2.4_1/: remove.
  • provider/: remove.
  • INSTALL: remove plugin references.
  • {{build,config}_win_plugin.bat,config_linux_{,static_}plugin.sh}: remove.
  • config_win.bat: remove plugin references.
  • src/{configdialog.cpp,onmainwindow{.cpp,{,_privat}.h}}: remove plugin references.
  • src/editconnectiondialog.cpp: do not connect signals to slots that do not exist on non-Linux platforms.
  • src/onmainwindow.cpp: add -nopn parameter to VcXsrv startup options, making the binary fail if it wasn't able to bind the requested port on all addresses.
  • src/onmainwindow.cpp: print out current DISPLAY value in debug log while starting X.Org Server on Windows.
  • src/onmainwindow.{cpp,h}: don't error out directly if starting the X.Org Server failed on Windows. Instead, try starting it three times, each time with a higher DISPLAY offset. On busy client machines, several clients raced for the sockets previously and often failed to start. Also check if the server binary actually is still alive before doing the TCP connection checks. A dead server won't be able to listen on a socket in the first place.
  • {src/{onmainwindow.{cpp,h},help.cpp},man/man1/x2goclient.1}: add new option --xserver-start-limit, replacing the formerly hardcoded limit of three tries.
  • src/onmainwindow.{cpp,h}: fix compile error on Windows - use std::size_t instead of std::ssize_t, treat zero as infinity value while parsing option value.
  • src/onmainwindow.cpp: handle a disabled X.Org Server start limit correctly.
  • src/onmainwindow.cpp: fix other compile errors/typos.
  • src/onmainwindow.cpp: another compile error/typo fix.
  • src/onmainwindow.cpp: let client recognize new --xserver-start-limit param correctly.
  • src/onmainwindow.cpp: add -silent-dup-error parameter to VcXsrv startup options, forcing it to silently fail without showing a dialog and thus keeping the process running.
  • src/onmainwindow.cpp: re-add periodic xmodmap keyboard sync for OS X/macOS platforms. Was dropped some time ago by accident.
  • src/onmainwindow.cpp: fix compile error on OS X/macOS.
  • copy-deps-win32.bat: update to 20160121-4 Cygwin bundle, shipping with chgrp.
  • src/onmainwindow.cpp: fix user-facing error messages in Windows X.Org Server startup functions.
  • src/pulsemanager.cpp: use QByteArray's constData () instead of data (), since we'll never modify the data anyway.
  • src/onmainwindow.cpp: hook-in chgrp for ~/.x2go/etc on Windows platforms to work around a Cygwin permissions bug. Fixes: #1156.
  • src/onmainwindow.cpp: QProcess:nullDevice () is only available on Qt 5.2+, so use a workaround for older versions.
  • src/onmainwindow.cpp: actually pass the correct group ID to the chgrp call and make sure that the warning dialog box also appears whenever the exit code indicates a failure.
  • src/onmainwindow.{cpp,h}: remove Cygwin permissions workaround via chgrp.
  • copy-deps-win32.bat: update to 20180615-1 Cygwin bundle, shipping with a further modified OpenSSH Server version at 7.7p1-1-x2go1 and without chgrp.

  • Remove plugin references.

  • x2goplugin{,-provider}.install: clear out.
  • {x2goplugin.dirs,x2goplugin-provider.dirs,x2goplugin-provider.links, x2goplugin-provider.post*}: remove.
