Descriptions

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.

La configuración de la autenticación en XWayland 1.16.x y 1.17.x anterior a 1.17.2 arranca el servidor en el modo de no autenticación, lo que permite a usuarios locales leer en o enviar información a clientes X11 arbitrarios a través de vectores que involucran un socket UNIX.

Multiple vulnerabilities have been found in X.Org X Server, the worst of which may allow authenticated attackers to read from or send information to arbitrary X11 clients. Versions less than 1.18.4 are affected.
