Silicon Graphics Inc. Security Advisory

Title: Program runpriv Security Issue
Number: 19970503-01-PX
Date: May 14, 1997
______________________________________________________________________________

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.

- - ------------------
- - --- Background ---
- - ------------------

The /usr/sysadm/bin/runpriv program is used by the System Desktop
to allow unprivileged users to run selected privileged commands.
Silicon Graphics has been informed of a potential security
vulnerability involving this 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
6.3 and 6.4. This issue will be corrected in future releases of IRIX.



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

The /usr/sysadm/bin/runpriv program is part of the Indigo Magic System
Administration subsystem of IRIX 6.3 and 6.4. Although other IRIX
versions will have similar Desktop System Administration subsystems,
only the IRIX 6.3 and 6.4 subsystems have the runpriv program. On
IRIX 6.3 and 6.4, the Indigo Magic System Administration subsystem
is installed by default.

A potential security vulnerability has been found that can result in
root privileges being obtained.

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

Publicity of this vulnerability has been limited and has afforded
Silicon Graphics Inc. the opportunity to fully investigate this issue
and provide the following information and solutions.



- - ---------------------
- - --- Temporary Fix ---
- - ---------------------

Although patches are available for this issue, it is realized that
there may be situations where installing the patches immediately many
not be possible.

The steps below can be used to remove the vulnerability by turning
off the privileges capability.


***************
*** WARNING ***
***************


Turning off the privileges capability will disable unprivileged
users using the visual administration tools. Only the root user
will be able to run these programs.


1) Become the root user on the system.

% /bin/su -
Password:
#


2) Turn off the privileges capability.

# chkconfig privileges off


3) Return to previous level.

# exit
$



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


**** IRIX 3.x and 4.x ****

Silicon Graphics Inc, no longer supports the IRIX 3.x and 4.x operating
systems and therefore has no patches to provide.



**** IRIX 5.x, 6.0, 6.0.1, 6.1, and 6.2 ****

These versions of IRIX do not have the /usr/sysadm/bin/runpriv program
and are therefore not vulnerable. No further action is required for
these versions.



**** IRIX 6.3 ****

For the IRIX operating system version 6.3 an inst-able patch has been
generated and made available via anonymous FTP and your service/support
provider. The patch is number 2077 and will install on IRIX 6.3 only.

The SGI anonymous FTP site is sgigate.sgi.com (204.94.209.1) or its
mirror, ftp.sgi.com. Patch 2077 can be found in the following
directories on the FTP server:

~ftp/Security

or

~ftp/Patches/6.3
