Luxembourg, February 1st, 2017

NoMachine is pleased to announce the immediate availability of version 5.2.11 which consolidates fixes and implementations made on the 5.1.0 branch. This release also delivers usability improvements such as providing an option to set the maximum number of applications running in a virtual Linux desktop and optimizations to the fail-over procedure in NoMachine Cluster environments.

Additionally, 5.2.11 includes a security update of OpenSSL (CVE-2017-3731) recently released to fix an out-of-bounds read flaw which could be exploited by a remote attacker to crash a 32-bit TLS/SSL server or client using OpenSSL. All customers are invited to update their NoMachine client and server installations. Version 4 customers please consult the announcement here.

IMPORTANT: This is the final scheduled update of the NoMachine 5 series in preparation for the upcoming version NoMachine 6. Aside from new functionality, this next milestone in our development roadmap will introduce some important changes in the NoMachine for Enterprise product structure.
