Update to X.Org Server 1.20.3, fixing a security issue. This might not affect MarIuX though.

From commit 9814e8f:

We are probably not affected, as our Xorg binary is not Suid.

$ ls -lh /usr/bin/Xorg
-rwxr-xr-x 1 root root 273 Oct 25 18:58 /usr/bin/Xorg

This is unfortunately just a wrapper:

$ more /usr/bin/Xorg
#!/bin/sh
#
# Execute Xorg.wrap if it exists otherwise execute Xorg directly.
# This allows distros to put the suid wrapper in a separate package.

basedir=/usr/libexec
if [ -x "$basedir"/Xorg.wrap ]; then
    exec "$basedir"/Xorg.wrap "$@"
else
    exec "$basedir"/Xorg "$@"
fi
$ ls -lh /usr/libexec/Xorg*
-rwsr-xr-x 1 root root 14M Feb 26 13:16 /usr/libexec/Xorg
-rwsr-xr-x 1 root root 33K Feb 26 13:16 /usr/libexec/Xorg.wrap

When Xorg.wrap is a suid wrapper, why is Xorg still setuid-root ?
