Testing in X servers built with Stack Protector restulted in an immediate crash when reading a user-proveded specially crafted font. As libXfont is used to read user-specified font files in all X servers distributed by X.Org, including the Xorg server which is often run with root privileges or as setuid-root in order to access hardware, this bug may lead to an unprivileged user acquiring root privileges in some systems.
