Branch: CURRENT, Version: 1.20.13, Package name: modular-xorg-xephyr-1.20.13, Maintainer: khorben

A kdrive based X Server which targets a window on a host X Server as its

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

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.
