./x11/modular-xorg-xwayland, Server for running X clients under Wayland from modular X.org

[ CVSweb ] [ Homepage ] [ RSS ] [ Required by ] [ Add to tracker ]

Branch: CURRENT, Version: 1.20.9, Package name: modular-xorg-xwayland-1.20.9, Maintainer: nia

XWayland is a fully fledged X server implementation that acts as a proxy
between X11 clients and a Wayland compositor.

It runs as a specialized Wayland client, while optionally using a set of
XWayland specific Wayland protocols for implementing certain functionality.

The Wayland compositor acts both as the Wayland display server XWayland
connects to, as well as the window manager.

X Server Pixel Data Uninitialized Memory Information Disclosure


Allocation for pixmap data in AllocatePixmap() does not initialize the
memory in xserver, it leads to leak uninitialize heap memory to
clients. When the X server runs with elevated privileges.

This flaw can lead to ASLR bypass, which when combined with other
flaws (known/unknown) could lead to lead to privilege elevation in the


A patch for this issue has been commited to the xorg server git
repository.  xorg-server 1.20.9 will be released shortly and will
include this patch.
