The X Window System is a graphical windowing system based on a client/server model.
An incorrect permission check for -modulepath and -logfile options when starting Xorg. X server allows unprivileged users with the ability to log in to the system via physical console to escalate their privileges and run arbitrary code under root privileges.
A local attacker can escalate privileges to root by passing crafted parameters to the X.org X server.
There is no known workaround at this time.
All X.Org X Server users should upgrade to the latest version:
# emerge --sync
# emerge --ask --oneshot --verbose ">=x11-base/xorg-server-1.20.3"
OS | Version | Architecture | Package | Version | Filename |
