X.Org security advisory: July 31, 2020
X Server Pixel Data Uninitialized Memory Information Disclosure
===============================================================
CVE-2020-14347
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
client.
Patch
=====
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.

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.

Classic description of "broken" :-)
1.17.4:
Fixes an uninitialized fd_set
1.17.3:
Various bugfixes across the board. The most visible changes include
fixing GLX extension setup under Xwayland and other non-Xorg servers
(enabling core contexts in more scenarios), and various stability fixes
to glamor and the Present extension.
A kdrive based X Server which targets a window on a host X Server as its
framebuffer.
Unlike Xnest it supports modern X extensions (even if host server
doesn't) such as Composite, Damage, randr etc (no GLX support now). It
uses SHM Images and shadow framebuffer updates to provide good
performance. It also has a visual debugging mode for observing screen
updates.
