NoMachine makes available version 9.4.14, introducing a number of improvements, along with updates to third‑party components affected by CVEs, as well as fixes for issues found in previous releases.

Changes to keys in configuration files

The new CustomXauthorityPath key in server.cfg, allows administrators to change the location of the .Xauthority file or to create separate .Xauthority files per virtual desktop session. This helps prevent XAUTHORITY conflicts in environments with shared home directories and is primarily intended for complex or enterprise deployments. The TokenExpiryTimeout key in server.cfg, lets you define the validity period of the token generated by the server to allow clients to reconnect after a connection failure. By default, the token remains valid for five minutes (300 s). Additionally, the 'EnableDbusLaunch' key in node.cfg has been renamed into 'EnableDbusWrapper'. This new key name is available for fresh new installations, updates will not rename the original EnableDbusLaunch key.

Ability to log-in automatically Linux Guest Users via web

Two new keys in server.cfg, EnableWebGuestsAutoLogin and ForceGuestUserCreation, enable seamless guest access to Linux web sessions, where system guests are automatically logged in to the system without encountering any login prompt.

Improvements to session list and export of history

A new option, the '--no-physical' parameter, allows you to exclude physical sessions from the output of session list commands ('nxserver --list', 'nxserver --connectionlist' and 'nxserver --history'). Another new parameter, '--filter item,value' applies the same logic of the '--format items_list' option but limits the output to entries matching the specified item-value pair. The full list of available items can be obtained by running 'nxserver --history --format'. Additionally, the 'nxserver --history' output can now be exported in JSON or CSV formats, facilitating data integration with external analysis platforms and third‑party tools.

OpenSSL

OpenSSL libraries shipped by NoMachine client and server packages are now v3.0.19. The full list of CVE patched by OpenSSL v3.0.19 is available on their Official web site https://github.com/openssl/openssl/releases/tag/openssl-3.0.19.

Perl

A patch for CVE-2024-56406 has been applied to the current Perl version shipped by NoMachine server packages. Details about the CVE are available at: https://nvd.nist.gov/vuln/detail/CVE-2024-56406

Important Notices

Customers of Enterprise Cloud Server Cluster v8 who wish to upgrade to v9 should refer to the instructions at: https://www.nomachine.com/AR11V01257. 'Online' subscriptions v9 for the enterprise products require a NoMachine server v9 and are not compatible with servers v8 or earlier. Please do not hesitate to contact us via any of the available channels for assistance.

All NoMachine Enterprise software for evaluation can now be activated using a license file which is generated from the User Area and activated online.  For further instructions, users can consult the following article https://kb.nomachine.com/AR10K00713.

The RPM packages are now built using a more recent version of RPM in order to support also SHA256 digest and to allow signature verification on recent RPM-based systems. On old OS versions like Open SUSE 11.2 and earlier, it will be necessary to install NoMachine tar.gz packages.

The current version doesn't provide full support for Wayland-native virtual desktops as required by adopting GNOME 49, a possible temporary solution is to downgrade GNOME or adopt a lightweight desktop. More details are available here: https://kb.nomachine.com/AR10W01330
