How to fix?

Upgrade Debian:9 xorg-server to version 2:1.19.2-1+deb9u2 or higher.

NVD Description

Note: Versions mentioned in the description apply only to the upstream xorg-server package and not the xorg-server package as distributed by Debian. See How to fix? for Debian:9 relevant fixed versions and status.

In X.Org Server (aka xserver and xorg-server) before 1.19.4, a local attacker authenticated to the X server could overflow a global buffer, causing crashes of the X server or potentially other problems by injecting large or malformed XKB related atoms and accessing them via xkbcomp.
