                      SGI Security Advisory

    Title:      IRIX cpr vulnerability
    Number:     20020409-01-I
    Date:       April 30, 2002
    Reference:  CAN-2002-0173


  • --- Issue Specifics ---

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.

These issues have been corrected IRIX 6.5.11 and later versions.


  • --- Impact ---

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


  • --- Temporary Workaround ---

If you don't use the Checkpoint Restart software, it can be uninstalled using the command:

# versions remove eoe.sw.cpr

If you use the software, then SGI recommends upgrading to IRIX 6.5.11 or later.


  • --- Solution ---

SGI has not provided patches for this vulnerability. Our recommendation is to upgrade to IRIX 6.5.11 or later.
