It's been reported that there is a potential buffer overflow vulnerability
in the /usr/sbin/cpr program. If successfully exploited, this can lead to a
root compromise.
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.

The cpr binary is installed by default on IRIX 6.5 systems as part of
eoe.sw.cpr (the SGI Checkpoint-Restart Software).
To see if cpr is installed, execute the following command:
$ versions eoe.sw.cpr
I = Installed, R = Removed
Name Date Description
I eoe 09/19/2000 IRIX Execution Environment, 6.5.10f
I eoe.sw 09/19/2000 IRIX Execution Environment Software
I eoe.sw.cpr 09/19/2000 SGI Checkpoint-Restart Software
If the command returns output similar to the above, then cpr is installed.
This vulnerability may not be exploited by a remote user, a local account
is required.
This vulnerability has been fixed in IRIX 6.5.11.
This vulnerability was assigned the following CVE:
http://cve.mitre.org/cgi-bin/cvename.cgi?name=CAN-2002-0173

using the command:
# versions remove eoe.sw.cpr
If you use the software, then SGI recommends upgrading to IRIX 6.5.11
or later.
