NVD Description

Note: Versions mentioned in the description apply to the upstream xorg-server package. See Remediation section below for Debian:10 relevant versions.

The authentication setup in XWayland 1.16.x and 1.17.x before 1.17.2 starts the server in non-authenticating mode, which allows local users to read from or send information to arbitrary X11 clients via vectors involving a UNIX socket.

Remediation

Upgrade Debian:10 xorg-server to version 2:1.17.2-1 or higher.
