Fedora 26 has launched a libvncserver patch that fixes critical buffer overflow vulnerabilities, boosting security and enhancing gnutls and gtk-vnc for a reliable remote desktop experience
Update to latest stable release, include fixes for gnutls and gtk-vnc compatibility.

Summary

LibVNCServer makes writing a VNC server (or more correctly, a program exporting

a frame-buffer via the Remote Frame Buffer protocol) easy.

It hides the programmer from the tedious task of managing clients and

compression schemata.

Update to latest stable release, include fixes for gnutls and gtk-vnc

compatibility.
