Rust-Based X11 Server Aims to Patch Decades of Security Gaps

A developer has released yserver, a ground-up X11 server in Rust, targeting real desktop use on Linux and BSD. Rust's compile-time memory safety eliminates vulnerability classes that have plagued Xorg's aging C codebase for decades—repeated privilege-escalation and corruption flaws. The project fills a gap where Wayland adoption remains incomplete.
