NoMachine makes available updated packages for version 8 to fix some issues affecting previous releases such as misleading error message when Kerberos authentication tickets are renewed, non-working propagation of profile rules from Cloud Server to Workstation Linux, and connections to Windows nodes not working when connecting via Cloud Server. Enhancements included are support for Swedish keyboard in web sessions and the possibility to set and display profile rules via CLI using the node name with the '--node-name NAME' parameter.

This release also updates the OpenSSL component to 1.1.1t following the recent advisory published by the OpenSSL project (CVE-2023-0286, CVE-2022-4304, CVE-2023-0215 and CVE-2022-4450). Additionally, the nxhtd component is now updated to be based on httpd 2.4.55 and relies on the last version of APR libraries, apr-1.7.2 and apr-util-1.6.3, which fix a number of security issues (CVE-2022-28331, CVE-2021-35940, CVE-2022-28331 and CVE-2022-25147).

All NoMachine users are advised to update their client and server installations with this latest NoMachine release which contains the updated OpenSSL and Apache libraries.

The complete list of fixes included in this 8.4.2 release are:

TR05R09717 - A misleading error message is printed in logs when Kerberos tickets are renewed
TR02U10772 - Cannot start up snap applications within NoMachine virtual sessions on systems using cgroupsv1

Important Notice

In NoMachine version 8, UPnP/NAT-PMP is disabled by default in the Free Edition. To get access to your computer over the internet, NoMachine's UPnP/NAT-PMP port mapping must be enabled by hand ('Server settings -> Ports' -> Select the service and click on Configure); or alternatively, your router can be configured with the appropriate port-forwarding rule. When port-mapping/port-forwarding is enabled, remote NoMachine connections, including connection requests from guests via the new Guest Desktop Sharing feature will be possible.
