1. Patch SG0003143 Release Note

       This release note describes patch SG0003143 to IRIX 6.2.

       This patch contains bug fixes for all platforms.

       This patch contains bug fixes for the X11 Execution
       Environment (versions 1232792130 and 1233007720) on a system
       running IRIX 6.2.  The software cannot be installed on other
       configurations.

       This patch contains fixes for the following bugs in IRIX
       6.2.  Bug numbers from Silicon Graphics bug tracking system
       are included for reference.

          o Bug #600678: Exploitable buffer overflow

          o Bug #617404: Memory leak in xterm

       This patch release includes these subsystems:

          o patchSG0003143.x_eoe_sw.eoe

       Because you want to install only the patches for problems
       you have encountered, patch software is not installed by
       default.  After reading the descriptions of the bugs fixed
       in this patch (see Section 1.3), determine the patches that
       meet your specific needs.

       If, after reading Sections 1.1 and 1.2 of these release
       notes, you are unsure whether your hardware and software
       meet the requirements for installing a particular patch, run
       inst.  The inst program does not allow you to install
       patches that are incompatible with your hardware or
       software.

       Patch software is installed like any other Silicon Graphics
       software product.  Follow the instructions in your Software
       Installation Administrator's Guide to bring up the miniroot


       form of the software installation tools.

       Follow these steps to select a patch for installation:

         1.  At the Inst> prompt, type

             install patchSGxxxxxxx

             where xxxxxxx is the patch number.

         2.  Initiate the installation sequence. Type

             Inst> go

         3.  You may find that two patches have been marked as
             incompatible.  (The installation tools reject an
             installation request if an incompatibility is
             detected.)  If this occurs, you must deselect one of
             the patches.

             Inst> keep patchSGxxxxxxx

             where xxxxxxx is the patch number.

         4.  After completing the installation process, exit the
             inst program by typing

             Inst> quit

       To remove a patch, use the versions remove command as you
       would for any other software subsystem.  The removal process
       reinstates the original version of software unless you have
       specifically removed the patch history from your system.

       versions remove patchSGxxxxxxx

       where xxxxxxx is the patch number.

       To keep a patch but increase your disk space, use the
       versions removehist command to remove the patch history.

       versions removehist patchSGxxxxxxx

       where xxxxxxx is the patch number.

No Requirements Information Available.

These checksums help to provide a 'signature' for the patch inst image which can be used to authenticate other inst images. You can obtain this kind of output by running sum -r on the image (from the command line):

32423      1   patchSG0003143
23124      1   patchSG0003143.idb
40988    213   patchSG0003143.x_eoe_sw
