                       SGI Security Advisory

     Title:  SNMP Vulnerabilities
    Number:  20020201-01-P
      Date:  April 3, 2002
 Reference:  CERT CA-2002-03
 Reference:  CVE CAN-2002-0013
 Reference:  CVE CAN-2002-0017

  • --- Issue Specifics ---

It has been reported that the IRIX /usr/etc/snmpd, /usr/etc/peer_encaps, and /usr/etc/peer_snmpd, when used with a public read-only community, can be made to dump core when running the publicly available "PROTOS Test-Suite: c06-snmpv1" regression tests, see:

http://www.ee.oulu.fi/research/ouspg/protos/testing/c06/snmpv1/

A buffer overflow in snmpd was also reported by Kris Hunt of ISS: http://www.iss.net/security_center/alerts/advise113.php

SGI is also investigating the non-base products that may have an SNMP component.

SGI has investigated the issues 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 in future releases of IRIX.


  • --- Impact ---

The above snmp daemons are not installed by default, they are part of the eoe.sw.netman package and can be optionally installed.

In order to check to see if this package is installed, run the following command:

# versions | grep netman

If the output of the above command looks like the following, then the daemons are installed and the system is vulnerable:

I eoe.sw.netman 03/14/2001 Network Management SNMP Support

These vulnerabilities may be exploited by a remote user, and no local account is required.

This issue was reported on CERT® Advisory CA-2002-03 Multiple Vulnerabilities in Many Implementations of the Simple Network Management Protocol (SNMP): http://www.cert.org/advisories/CA-2002-03.html

The PROTOS vulnerability was assigned the following CVE: http://cve.mitre.org/cgi-bin/cvename.cgi?name=CAN-2002-0013

The ISS SNMP buffer overflow was assigned the following CVE: http://cve.mitre.org/cgi-bin/cvename.cgi?name=CAN-2002-0017


  • --- Temporary Workaround ---

The only workaround for these problems is to uninstall the product using the following commands:

# versions remove eoe.sw.netman

SGI recommends either upgrading to IRIX 6.5.16 when it is released, or installing the appropriate patch from the listing below.


  • --- Solution ---

SGI has provided a series of patches for these vulnerabilities. Our recommendation is to upgrade to IRIX 6.5.16 when available, or install the appropriate patch.
