(Debian Issues Fix) Many Simple Network Management Protocol (SNMP) Implementations Allow Remote Users to Deny Service or Obtain Access to the System
SecurityTracker Alert ID:  1003554
SecurityTracker URL:  http://securitytracker.com/id/1003554
CVE Reference:   CAN-2002-0012, CAN-2002-0013   (Links to External Site)
Date:  Feb 14 2002
Impact:   Denial of service via network, Execution of arbitrary code via network, Root access via network, User access via network
Fix Available:  Yes  Vendor Confirmed:  Yes  

Description:   CERT reported that the University of Oulu (Finland) has discovered vulnerabilities in many vendor implementations of the Simple Network Management Protocol (SNMP) version 1.

The Oulu University Secure Programming Group (OUSPG, http://www.ee.oulu.fi/research/ouspg/) reports that there are numerous vulnerabilities in SNMPv1 implementations from many different vendors. A remote user can reportedly cause denial of service attacks or gain elevated privileges on the system.

The extent of the vulnerabilities depends on the specific vendor implementation. Vulnerabilities apparently include denial-of-service conditions, format string vulnerabilities, and buffer overflows. Some vulnerabilities do not require the request message to use the correct SNMP community string, according to CERT.

OUSPG reportedly performed two sets of tests of SNMP request message handling: one test focused on ASN.1 decoding, and the second looked for exceptions in the processing of the decoded data. The testers used the PROTOS c06-snmpv1 test suite:

http://www.ee.oulu.fi/research/ouspg/protos/testing/c06/snmpv1/0100.html

Some of the products implement defective SNMPv1 trap handling. A remote user can reportedly send a specially crafted SNMP trap message to an SNMP manager to trigger the vulnerability.

Some of the products implement defective SNMPv1 request handling. A remote user can reportedly send a specially crafted SNMP request message to an SNMP agent to trigger the vulnerability.

Specific technical results were not available at the time of this entry. However, CERT reports that the following vendors are affected to some degree:

3Com,
AdventNet,
CacheFlow,
Caldera,
Cisco,
Compaq,
Computer Associates,
COMTEK Services,
FreeBSD,
Hewlett Packard,
Hirschmann Electronics,

Juniper Networks,
Lantronix,
Lotus,
Lucent,
Marconi,
Microsoft,
Multinet,

CERT has provided more information at the following URLs:

http://www.kb.cert.org/vuls/id/854306
http://www.kb.cert.org/vuls/id/107186

Impact:   A remote user may be able to cause denial of service conditions or may be able to obtain elevated privileges on the system.
Solution:   The vendor has released a fix for net-snmp (formerly known as ucd-snmp) on Debian GNU/Linux 2.2 alias potato:

Potato was released for alpha, arm, i386, m68k, powerpc and sparc.

Package        : ucd-snmp
Problem type   : remote exploit
Debian-specific: no
CERT Advisory  : CA-2002-03

The Secure Programming Group of the Oulu University did a study on
SNMP implementations and uncovered multiple problems which can
cause problems ranging from Denial of Service attacks to remote
exploits.

New UCD-SNMP packages have been prepared to fix these problems
as well as a few others. The complete list of fixed problems is:

* When running external programs snmpd used temporary files insecurely
* snmpd did not properly reset supplementary groups after changing
  its uid and gid
* Modified most code to use buffers instead of fixed-length strings to
  prevent buffer overflows
* The ASN.1 parser did not check for negative lengths
* the IFINDEX response handling in snmpnetstat did not do a sanity check
  on its input

(thanks to Caldera for most of the work on those patches)

The new version is 4.1.1-2.1 and we recommend you upgrade your
snmp packages immediately.

wget url
        will fetch the file for you
dpkg -i file.deb
        will install the referenced file.
