An update for libvncserver is now available for openEuler-22.03-LTS Security Advisory openeuler-security@openeuler.org openEuler security committee openEuler-SA-2022-2090 Final 1.0 1.0 2022-11-11 Initial 2022-11-11 2022-11-11 openEuler SA Tool V1.0 2022-11-11 libvncserver security update An update for libvncserver is now available for openEuler-22.03-LTS. libvncserver is a set of programs using the RFB (Remote Frame Buffer) protocol. They are designed to "export" a frame buffer via net: you set up a server and can connect to it via VNC viewers. If the server supports WebSockets (which LibVNCServer does), you can also connect using an in-browser VNC viewer like noVNC. It is already in wide use for administration, but it is not that easy to program a server yourself.
