By providing a modified bitmap to the X.Org Server, a heap-based buffer overflow privilege escalation can occur.

Maybe we should stop writing security critical software in memory unsafe languages. I now this vulnerability was introduced a long time ago, but given that major Wayland compositors are still written in C, something like this isn’t too unlikely to happen again.

Unlike X11, Wayland was never intended to be network transparent. As others say, solutions like waypipe and more tradionally RDP and VNC exist.
