- --- 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=AE Advisory CA-2002-03 Multiple Vulnerabi=
lities
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=3DCAN-2002-0013
The ISS SNMP buffer overflow was assigned the following CVE:
http://cve.mitre.org/cgi-bin/cvename.cgi?name=3DCAN-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 th=
e
appropriate patch.
