US-CERT Vulnerability Note VU#854306 - Multiple vulnerabilities in SNMPv1 request handling - Feb, 2002

Please note that the CERT Coordination Center of the Software Engineering Institute at Carnegie Mellon University, Pittsburgh, Pennsylvania, U.S.A. in co-ordination with the Secure Programming Group at Oulu University in Finland have posted a security advisory regarding SNMPv1 management protocol.  It deals with the manner in which SNMPv1 agents and managers handle request and trap messages.  The full text can be viewed at http://www.cert.org/advisories/CA-2002-03.html.

Associated with the advisory are test suites for testing susceptibility to the identified problems.  These can be found at http://www.ee.oulu.fi/research/ouspg/protos/testing/c06/snmpv1/.

NuDesign has applied the test suites and found that our SNMP Agent and SNMP Trap receiving products were susceptible to this vulnerability.  The required corrections have been applied and new versions of corrected NuDesign products have been released to customers with support contracts on Feb 18, 2002.  Similarly corrected, free evaluations available for download from this site, have been upgraded on Feb 18, 2002.

The following products have been tested and no vulnerability has been detected, irrespective of their version number: Visual MIBuilder®, SNMP Agent Discovery Control, SNMP MIB Compiler Control, SNMP Trap Sender Control and SNMP Management Control.

The following products have been corrected for the SNMPv1 vulnerability (starting with version numbers listed here and above):

Please upgrade the above products as soon as possible via our Customer's Zone links above if you are a Support Contract customer, or contact the NuDesign sales department if you need to obtain a Support Contract.
