(SGI Issues Fix) SGI IRIX gr_osview Command Line Buffer Overflow Yields Root Privileges to Local Users
SecurityTracker Alert ID:  1008987
SecurityTracker URL:  http://securitytracker.com/id/1008987
CVE Reference:   CVE-2000-0797   (Links to External Site)
Date:  Feb 9 2004
Impact:   Execution of arbitrary code via local system, Root access via local system
Fix Available:  Yes  Vendor Confirmed:  Yes  

Description:   A vulnerability was reported in the SGI IRIX gr_osview utility. A local user can gain root privileges.

In January 1997, the Last Stage of Delirium reported a buffer overflow vulnerability in gr_osview. A local user can reportedly supply a specially crafted '-D' command line option to execute arbitrary code with root privileges.

A demonstration exploit is available at:

http://lsd-pl.net/files/get?IRIX/irx_gr_osview

Impact:   A local user can execute arbitrary code with root privileges.
Solution:   SGI has issued a fixed version of IRIX (6.5.23) and has also issued the following patches:

For IRIX 6.5.18m, 6.5.18f, 6.5.19m, 6.5.19f, 6.5.20m, and 6.5.20f, use patch 5473.

For IRIX 6.5.21m, 6.5.21f, and 6.5.22, use patch 5474.

- --- Update ---
- --------------

This is an update to SGI Security Advisory 20040104-01-P

The original patch 5424 had two library mismatches causing 4Dwm to hang
with rld errors appearing in SYSLOG and problems with gr_osview.  New patches
5473 and 5474 have been released to fix these issues. (SGI BUG 908652)


- -----------------------
- --- Issue Specifics ---
- -----------------------

It has been reported thru various channel that there are several
vulnerabilities affecting applications on IRIX.

 * html2ps vulnerability                  (SGI BUG 871671)
   - http://www.suse.com/de/security/2002_040_lprng_html2ps.html

 * Safe.pm security hole                  (SGI BUG 876818)
   - http://use.perl.org/articles/02/10/06/1118222.shtml?tid=5

 * gzexe and gznew predicatble tmp files  (SGI BUG 892846)
   - http://www.debian.org/security/2003/dsa-308

 * libdesktopicon.so buffer overflow      (SGI BUG 902169)
   - http://www.lsd-pl.net/

 * gr_osview buffer overflow              (SGI BUG 902173)
   - http://www.lsd-pl.net/

SGI 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.  This issue has been
corrected in future releases of IRIX.


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

To determine the version of IRIX you are running, execute the following
command:

  # /bin/uname -R

That will return a result similar to the following:

  # 6.5 6.5.21f

The first number ("6.5") is the release name, the second ("6.5.21f" in
this case) is the extended release name.  The extended release name
is the "version" we refer to throughout this document.


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

SGI has provided a series of patches for these vulnerabilities. Our
recommendation is to upgrade to IRIX 6.5.23, or install the appropriate
patches.
