X.Org — Vulnerabilities & Security Advisories 13

X.org serves as the primary display server for Linux and Unix systems, managing graphical interfaces and input devices. Historically, it has been susceptible to remote code execution, buffer overflows, and privilege escalation vulnerabilities, often through malformed protocol requests or insufficient input validation. While no major public incidents have been widely documented, the project's 13 recorded CVEs highlight ongoing security concerns, particularly in older versions. Its open-source nature allows for rapid vulnerability disclosure and patching, though legacy deployments may remain exposed. Security improvements have focused on memory safety and protocol hardening to mitigate risks associated with its complex, network-facing architecture.
