NOVELL TECHNICAL INFORMATION DOCUMENT TITLE: SNMP vulnerability fix for NW 4.x, 5.x, 6.x TID #: 2961546 README FOR: SNMPFIX.EXE NOVELL PRODUCTS and VERSIONS: NetWare 5 NetWare for Small Business 4.2 NetWare 4.2 NetWare 5.1 ZENworks for Servers NetWare 6 ABSTRACT: This patch addresses the SNMP Vulnerability issues listed in the Issues Section of this readme. The files SNMPLOG.NLM & SNMPLOG.MSG are the same as the ones we ship with NW5.1 SP4 and NW6 SP1. But the files SNMP.NLM & SNMP.MSG are newer in this TID than the files shipping in NW5.1 SP4 and NW 6 SP1. Hence if the support pack is already applied then only SNMP.NLM & SNMP.MSG has to be replaced else all the the four files have to be replaced. These modules will not be in a NetWare 4.x Support Pack. This was tested on 4.11, 4.2, 5.0, 5.1, and 6.0 only. ----------------------------------------------------------------- DISCLAIMER THE ORIGIN OF THIS INFORMATION MAY BE INTERNAL OR EXTERNAL TO NOVELL.

ISSUE: THIS PATCH ADDRESS THE FOLLOWING ISSUES VU#107186 - Multiple vulnerabilities in SNMPv1 trap handling SNMP trap messages are sent from agents to managers. A trap message may indicate a warning or error condition or otherwise notify the manager about the agent's state. SNMP managers must properly decode trap messages and process the resulting data. In testing, OUSPG found multiple vulnerabilities in the way many SNMP managers decode and process SNMP trap messages. VU#854306 - Multiple vulnerabilities in SNMPv1 request handling SNMP request messages are sent from managers to agents. Request messages might be issued to obtain information from an agent or to instruct the agent to configure the host device. SNMP agents must properly decode request messages and process the resulting data. In testing, OUSPG found multiple vulnerabilities in the way many SNMP agents decode and process SNMP request messages.
