- --- Issue Specifics ---
- -----------------------
It has been reported thru various channel that there are several
security issues affecting IRIX networking.
* various fixes to mitigate the non-network consequences of
extreme UDP/interrupt DoS attacks (SGI BUG 773203, 897764)
* blocking SYN+FIN and illogical TCP flags combos from achieving
3-way handshake (SGI BUG 871383)
http://online.securityfocus.com/archive/1/296558/2002-10-19/2002-10-25/1
* ifconfig "-arp" argument does not disable arp requests being
sent or received (SGI BUG 890567)
* arp DOS vulnerability (SGI BUG 902072)
http://www.auscert.org.au/render.html?it=3489&cid=1
These patches also contain non-security fixes. Note that on IRIX 6.5.20
thru IRIX 6.5.22 two patches are required. Both patches MUST be
installed together or system instability could occur.
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.

NOTES
1) This version of the IRIX operating has been retired or no
longer actively supported. Upgrade to an actively supported
IRIX operating system. See http://support.sgi.com for
more information.
2) If you have not received an IRIX 6.5.X CD for IRIX 6.5, contact
your SGI Support Provider or URL: http://support.sgi.com
3) Install the required patch(es) based on your operating release.
Note that on IRIX 6.5.20 thru IRIX 6.5.22 two patches are required.
Both patches MUST be installed in order to prevent system instability.
