Silicon Graphics Inc. Security Advisory

Title: Permissions issue with IRIX 5.0.x, 5.1.x, 5.2, 5.3,
Title: 6.0.x, 6.1 and 6.2 Desktop searchbook Program
Number: 19961201-01-PX

______________________________________________________________________________

Silicon Graphics provides this information freely to the SGI user community
for its consideration, interpretation, implementation and use. Silicon
Graphics recommends that this information be acted upon as soon as possible.

Silicon Graphics will not be liable for any indirect, special, or
consequential damages arising from the use of, failure to use or improper
use of any of the instructions or information in this Security Advisory.
______________________________________________________________________________


Silicon Graphics Engineering and Worldwide Customer Service divisions
have become aware of a potential security issue in the IRIX 5.0.x, 5.1.x,
5.2, 5.3, 6.0.x, 6.1 and 6.2 /usr/sbin/searchbook program.

Silicon Graphics Inc. has investigated the issue and recommends the
following steps for neutralizing the exposure. It is HIGHLY RECOMMENDED
that these measures be implemented on ALL SGI systems running IRIX versions
5.0.x, 5.1.x, 5.2, 5.3, 6.0.x, 6.1 and 6.2. This issue will be corrected
in future releases of IRIX.



- ---------------
- ---- Impact ---
- ---------------

The purpose of the /usr/sbin/searchbook program is to find desktop icons
locally and remotely.

A potential security issue can occur when using the /usr/sbin/searchbook
program resulting in incorrect permissions of 666 on the user files
<home dir>/.desktop-<hostname>/iconbook and
<home dir>/.desktop-<hostname>/searchbook.

A local account is required inorder to exploit this vulnerability both
locally and remotely.



- -----------------
- ---- Solution ---
- -----------------


**** IRIX 4.x ****

This version of IRIX is not vulnerable as the /usr/sbin/searchbook
program is not part of this IRIX version. No action is required.



**** IRIX 5.0.x and 5.1.x ****

There is no patch available for IRIX operating system versions 5.0.x
and 5.1.x.

It is possible to upgrade the system to IRIX 5.2 or higher and
then install the security patch for that version. See the sections
below for IRIX 5.2 and higher for more information.



**** IRIX 5.2 ****

For the IRIX operating system version 5.2 an inst-able patch
has been generated and made available via anonymous FTP and your
service/support provider. The patch is number 1595 and will install
only on IRIX 5.3.
