The X Window system provides a Graphical User Interface (GUI) where users can have multiple windows in which to run programs and various add on. The X Window system is typically used on desktops where users login, but not on servers where users typically do not login.
Note: The patch can lead to login loop hence it is advised to check official page.
Rationale:
Unless your organization specifically requires graphical login access via X Windows, remove it to reduce the potential attack surface.
Fix:
Uninstall X Windows:
# apt-get purge xserver-xorg-core*
Parameter:
[yes/no]
Technical Mechanism:
Uninstall X Windows:
# apt-get purge xserver-xorg-core*
