Silicon Graphics Inc. Security Advisory

Title: IRIX rld security vulnerability
Number: 19970504-01-PX
Date: May 28, 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.

Silicon Graphics provides the information in this Security Advisory on
an "AS-IS" basis only, and disclaims all warranties with respect thereto,
express, implied or otherwise, including, without limitation, any warranty
of merchantability or fitness for a particular purpose. In no event shall
SGI be liable for any loss of profits, loss of business, loss of data or
for any indirect, special, exemplary, incidental or consequential damages
of any kind arising from your use of, failure to use or improper use of
any of the instructions or information in this Security Advisory.
______________________________________________________________________________



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

A security vulnerability has been found with the runtime linker program,
rld, distributed in IRIX 5.x and 6.x.

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 vulnerable SGI systems running
IRIX 5.x and 6.x versions. This issue has been corrected in more
recent releases of IRIX and will be corrected in future releases of IRIX.



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


With normal installation, the runtime loader comes from the
compiler_eoe.sw.unix subsystem and installs the program as /lib/rld.
The compiler_eoe.sw.unix subsystem is installed by default on all systems.

When running setuid and setgid programs, the rld program could be
manipulated to bypass existing permissions. Local non-privileged
users could gain root access.

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

It is believed that this vulnerability information is not public
knowledge and this has afforded SGI the opportunity to fully investigate
this issue and provide the following information and solutions.



- - - - --------------------------
- - - - --- Temporary Solution ---
- - - - --------------------------


Unfortunately, there are no immediate or temporary workarounds for
this issue. The issue can only be addressed with a patch.



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


**** IRIX 5.0.x, 5.1.x, and 5.2 ****
