    Synopsis
    ========

    Multiple vulnerabilities have been discovered in the Xorg Server and
    XWayland, the worst of which can result in privilege escalation or
    remote code execution.

    Background
    ==========

    The X Window System is a graphical windowing system based on a
    client/server model.

    Affected packages
    =================

    Package Vulnerable Unaffected
    -------------------- ------------ ------------
    x11-base/xorg-server < 21.1.11 >= 21.1.11

    Description
    ===========

    Multiple vulnerabilities have been discovered in X.Org X Server and
    XWayland. Please review the CVE identifiers referenced below for
    details.

    Impact
    ======

    The X server can be crashed by a malicious client, or potentially be compromised for remote code execution in environments with X11
    forwarding.

    Workaround
    ==========

    Users can ensure no untrusted clients can access the running X
    implementation.

    Resolution
    ==========
