Abstract

This document describes the bugs fixed and the features added in
XFree86 3.3.2 compared with the 3.3.1 release, It also includes
installation instructions for the binary distributions. This version
has been updated to include information about the first three public
patches for XFree86 3.3.2. It is strongly recommended that anyone
using XFree86 update to version 3.3.2 + patch 3.

1. XFree86 and X11R6.3

XFree86 releases starting with the 3.2A beta are based on the X Consortium's
X11R6.3 (the final release from the X Consortium).

R6.3 is an update to R6.1, and is intended to be compatible with R6.1 and R6 at
the source and protocol levels. Binaries should be upward-compatible. X11R6.3
includes some new Xserver extensions: SECURITY, XC-APPGROUP, XpExtension (print
extension), and an updated, and standardised version of LBX. X11R6.3 also has
new standards, including RX (X Remote Execution MIME type), and a proxy manage-
ment protocol. X11R6.3 includes support for gzipped fonts.

R6.1 is an update to R6, and is intended to be compatible with R6 at the source
and protocol levels. Binaries should be upward-compatible. X11R6.1 includes
some new Xserver extensions: DOUBLE-BUFFER, XKEYBOARD and RECORD.

What about R6.2? X11R6.2 is the name given to a subset of X11R6.3, which has
only the print extension and the Xlib implementation of vertical writing and
user-defined character support in addition to those features included in R6.1.

2. OS issues

Always check the OS specific README files for special requirements or caveats.

Users running Linux should note that Elf is now the only binary type supported
for Linux OSs. This means that binaries for ix86/a.out and AXP/ECOFF are not
available with this release.

3. What's new in 3.3.2 patch 3?

3.3.2 patch 3 (aka 3.3.2.3) fixes some additional security problems in both the

Release Notes for XFree86[tm] 3.3.2 + patch 3 2

server and the libraries. It fixes two small xterm problems as well. The prob-
lem with shared IRQ in the Riva128 driver has been solved.

4. What's new in 3.3.2 patch 2?

3.3.2 patch 2 (aka 3.3.2.2) fixes some security bugs, a denial of service prob-
lem with xdm, a few gcc 2.8.x-related build problems and updates scanpci. The
security bugs fixed are buffer overruns in the X11, Xt, Xaw and Xmu libraries.
This affects xterm and any other setuid-root program that uses these libraries.

5. What's new in 3.3.2 patch 1?

3.3.2 patch 1 (aka 3.3.2.1) fixes some security bugs, and some bugs in xterm.
The security bugs fixed are buffer overruns in xterm related to the input-
Method, preeditType, and *Keymap resources, and buffer overruns in the Xaw
library related to the inputMethod and preeditType resources. The xterm prob-
lem represents a security vulnerability for any platform where xterm is
installed setuid-root (as is the case for all XFree86 platforms). The Xaw
problem represents a security vulnerability for any setuid-root program that
uses the Xaw library (including xterm).

The other xterm bugs fixed are:

o Incorrect utmp handling is fixed. The 3.3.2 version of xterm wasn't cor-
rectly removing utmp entries when it exits.

o Mishandling of the -vb command line option is fixed.

o A problem that could lead to an invisible cursor has been fixed.

6. What's new in 3.3.2?

6.1 Security fixes

o Several buffer overrun problem discovered since the release of
XFree86-3.3.1 have been fixed

o Several insecure X server command line options have been removed

o The X servers now run the xkbcomp program under the user's real uid

o Additionally, a wrapper program for the X servers has been added which
eliminated the need for the servers to be installed SUID root

6.2 Bug fixes

o A black screen problem in the Tseng driver has been fixed.

6.4 Known Problems

o There are problems with some Cirrus laptop chipsets (75xx). The driver
seems to work for some people, but not others. Until someone with the
appropriate hardware can look into this, these problems are unlikely to be
fixed. If you wish to work on this, please contact us. We don't need
testers, we need people willing and able to fix the problems.

o There are problems with some of the Trident laptop chipsets. The driver
seems to work in a limited way for some people, but not others. Until
someone with the appropriate hardware can look into this, these problems
are unlikely to be fixed. If you wish to work on this, please contact us.
We don't need testers, we need people willing and able to fix the prob-
lems.

7. Installing the XFree86 3.3.2 Release

The XFree86 3.3.2 binaries are distributed as a full release.

NOTE: the X servers are no longer installed setuid root. If you are starting
your X servers with startx/xinit, or something similar, you will need a copy of
the setuid Xwrapper, and an updated xinit. These can be found in X3323bin.tgz.

What follows is a list of the XFree86 3.3.2 components. There may be some
variations in this for some OSs.

Release Notes for XFree86[tm] 3.3.2 + patch 3 6

The following are required for all new installations:

preinst.sh Pre-installation script
postinst.sh Post-installation script
extract XFree86 extraction utility
X3323bin.tgz Clients, run-time libs, and app-defaults files
X332doc.tgz Documentation
X332fnts.tgz 75dpi, misc and PEX fonts
X3323lib.tgz Data files required at run-time
X332man.tgz Manual pages
X332set.tgz XF86Setup utility
X3323VG16.tgz 16 colour VGA server (XF86Setup needs this server)
X3323upd.tgz XFree86 3.3.2 patch 3 update
X332cfg.tgz sample config files for xinit, xdm

NOTE: Be very careful about installing X332cfg.tgz over an existing installa-
tion if you have customised your xinit and/or xdm config files. Installing
X332cfg.tgz will overwrite any existing files. If you do have customised
files, there is no need to install X332cfg.tgz.

NOTE: The bitmap fonts distributed with this release are compressed using gzip
rather than compress. This means that you will probably want to remove the old
versions (after backing them up). The Xservers and font server in releases
prior to 3.2A cannot read gzipped fonts, so keep a copy of the old fonts if you
wish to run older servers.

The following X servers are for PC/AT based hardware (i.e., typical Intel ix86
based PCs). Choose at least one which matches your hardware, as well as the
VGA16 server. The VGA16 server is required by the new configuration utility
(XF86Setup).

If you already have a version of XFree86 installed, MAKE A BACKUP OF /usr/X11R6

Release Notes for XFree86[tm] 3.3.2 + patch 3 8

BEFORE DOING ANYTHING ELSE. The standard installation procedure will overwrite
your existing version of XFree86.

If you are installing from scratch, create a directory called /usr/X11R6, then
extract the required .tgz files. If you don't have enough space in /usr for
this, create a directory elsewhere and create a symbolic link to it. E.g., if
you create a directory in /home:

mkdir /home/X11R6
ln -s /home/X11R6 /usr

The next step is to run the pre-installation script. This script makes some
preliminary checks of your system. For some OSs, it may tell you to install
new versions of some system components before proceeding with the installation.
This script may also remove some outdated files and symbolic links from a pre-
vious installation that could cause problems.

For the purposes of these installation instructions, it is assumed that you
have downloaded all the files to the /var/tmp directory. If you've put them in
another directory, that's fine -- just replace all occurrences of ``/var/tmp''
with the name of that directory.

To run the pre-installation script, go to /usr/X11R6 and run it:

cd /usr/X11R6
sh /var/tmp/preinst.sh

The next step is to make the installation utility executable. To do this, make
sure the `extract' file is in the same directory as all the X332*.tgz files,
and run the following from that directory:

chmod 755 extract

The installation utility ``extract'' is used to unpack the .tgz files that make
up the XFree86 distribution. The .tgz files are gzipped tar files. However,
``tar'' in its standard form on most OSs is not well-suited to the task of
installing XFree86. The extract utility is a modified version of GNU tar 1.12
built with the options required to make it suitable for installing XFree86.
The source for extract is available from the same place you got the XFree86
distribution.

It is strongly recommended that you use the provided extract utility to unpack
the XFree86 distribution. If you choose to ignore this and use something else,
we don't want to hear from you if you run into problems. It is also important
that you do not rename the extract utility. If renamed, it behaves just like
the normal GNU tar.

To extract the XFree86 binaries, run the following as root:

cd /usr/X11R6
/var/tmp/extract /var/tmp/X332[a-z]*.tgz
/var/tmp/extract /var/tmp/X3323[8-z]*.tgz

Once the required .tgz files have been extracted, run the post installation

Release Notes for XFree86[tm] 3.3.2 + patch 3 9

script:

cd /usr/X11R6
sh /var/tmp/postinst.sh

For OSs which use ldconfig, you may need to run ldconfig or reboot to complete
the installation. The postinst.sh script should run ldconfig correctly for you
if you are using Linux, FreeBSD, NetBSD or OpenBSD. For other OSs that use
ldconfig, check how it normally gets run at boot time.

8. Updating XFree86 3.3.2 to XFree86 3.3.2 patch 3

The following is required to update an XFree86 3.3.2 installation to XFree86
3.3.2 patch 3:

extract XFree86 extraction utility
X3323upd.tgz XFree86 3.3.2 patch 3 update
X3323{SERVER}.tgz Patch 3 Server update from Servers/PC98_Servers directory
You must select the appropriate SERVER file for the
server that you are currently running (i.e. X3323S3.tgz).

First make the extract utility executable by running:

chmod 755 extract

To update your installation to 3.3.2 patch 3, run the following as root:

cd /usr/X11R6
/var/tmp/extract /var/tmp/X3323upd.tgz
/var/tmp/extract /var/tmp/X3323{SERVER}.tgz

NOTE: X3323upd.tgz supersedes the previous update (X3322upd.tgz), so there is
no need to have installed X3322upd.tgz before installing X3323upd.tgz.
