The X.Org Foundation — Vulnerabilities & Security Advisories 11

The X.Org Foundation develops and maintains the X Window System, a core display server technology for Linux and Unix systems. Historically, vulnerabilities in X.Org components frequently include remote code execution, memory corruption flaws, and privilege escalations, often stemming from boundary errors in parsing or rendering. While no major security incidents have been widely documented, the project maintains 11 CVEs on record, with many addressing issues in libX11 and related libraries. Security updates are regularly released, but the complexity of X11's architecture continues to present potential attack surfaces, particularly in environments where untrusted clients interact with the display server.
