XORG 1.11 Critical Vulnerability Found

In XORG version 1.11 (Fedora 16, Arch Linux, Fuduntu, Debian unstable regardless of the working environment) and above, a critical vulnerability has been discovered that allows not having a password to pass its query in lockscreens (Screensaver, xscreensaver kscreenlocker, etc.) using elementary combination CTRL + ALT + * (the one on the nampad).

In Ubuntu Xorg version 1.10.4, so this OS is not affected by this vulnerability. Version XORG 1.11 is scheduled for submission at 12.04, but I think by this time they will have time to fix this bug.

I wonder how with this case at BSDeshnikov, Solarisnikov and TP?
