Maybe try building from master branch.
https://gitlab.freedesktop.org/xorg/xserver

I believe that should alreay been fixed there.

See:
https://gitlab.freedesktop.org/xorg/xserver/-/commit/8c4a015cc2e09dd9314e9e5e33c22765b4ea7474

Haven't seen practically seen it yet, but there's chance that by
requesting a the some non-existing but long enough color name, the
lookup loop could overflow on the text block. Didn't actually test it,
but something like "YellowBlueGarbageFooBar" could be enough. Depending
on what the compiler actually created, this could reach out of the
.cdata section into some non-readable (or non-mapped) page, thus leading
to segfault.
