| Wade Alcorn and John Heasman of NGSSoftware have discovered a stack overflow vulnerability in Castle Rock Computing SNMPc Network Manager. SNMPc Network Manger is a distributed network management system that allows monitoring of the network infrastructure. It employs a distributed polling agent architecture which uses SNMP TRAPs to provide a solution capable of monitoring networks with up to ten thousand devices. An SNMP TRAP initiated by a network element is sent to the SNMPc Network Manager to allow monitoring of the infrastructure. |

Vulnerable Systems:
* SNMPc versions 7.1 and earlier
Immune Systems:
* SNMPc version 7.1.1
The vulnerability can be exploited when an overly long community string is sent in the SNMP TRAP packet. The packets format will be valid ASN.1, including the length of the community string. An attacker can craft a single UDP packet that can lead to the execution of arbitrary code in the context of LocalSystem.
