- - --- 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.
