An arbitrary file overwrite vulnerability in NoMachine Free Edition and Enterprise Client for macOS before v8.8.1 allows attackers to overwrite root-owned files by using hardlinks.
The nxfs.sys driver in the DokanFS library 0.6.0 in NoMachine before 6.4.6 on Windows 10 allows local users to cause a denial of service (BSOD) because uninitialized memory can be read.
An uninitialised stack variable in the nxfuse component that is part of the Open Source DokanFS library shipped with NoMachine 6.0.66_2 and earlier allows a local low privileged user to gain elevation of privileges on Windows 7 (32 and 64bit), and denial of service for Windows 8 and 10.
