Subject: Security ERRATA Low: xorg-x11-server on SL6.x i386/x86_64
Newsgroups: gmane.linux.scientific.errata
Date: Monday 9th December 2013 16:02:42 UTC (over 2 years ago)
Synopsis:          Low: xorg-x11-server security and bug fix update
Advisory ID:       SLSA-2013:1620-2
Issue Date:        2013-11-21
CVE Numbers:       CVE-2013-1940
--

A flaw was found in the way the X.org X11 server registered new hot
plugged devices. If a local user switched to a different session and
plugged in a new device, input from that device could become available in
the previous session, possibly leading to information disclosure.
(CVE-2013-1940)

This update also fixes the following bugs:

* A previous upstream patch modified the Xephyr X server to be resizeable,
however, it did not enable the resize functionality by default. As a
consequence, X sandboxes were not resizeable on Scientific Linux 6.4 and
later. This update enables the resize functionality by default so that X
sandboxes can now be resized as expected.

* In Scientific Linux 6, the X Security extension (XC-SECURITY) has been
disabled and replaced by X Access Control Extension (XACE). However, XACE
does not yet include functionality that was previously available in XC-
SECURITY. With this update, XC-SECURITY is enabled in the xorg-x11-server
spec file on Scientific Linux 6.

* Upstream code changes to extension initialization accidentally disabled
the GLX extension in Xvfb (the X virtual frame buffer), rendering headless
3D applications not functional. An upstream patch to this problem has been
backported so the GLX extension is enabled again, and applications relying
on this extension work as expected.
