Astracon Information for VU#107186
Multiple vulnerabilities in SNMPv1 trap handling
The Astracon Stinger NetConnect is safe against the vulnerability reported by VU#107186. The Stinger NetConnect processes SNMP responses only. Since the trap demon is never invoked, the Stinger NetConnect will never receive a trap; it is always safe.
The Stinger NetConnect doesn't accept SNMP requests, but can send SNMP version 1 or version 3 requests. By configuring the NetConnect to use only SNMP version 3, the vulnerabilities caused when using SNMP version 1 in the network will be avoided.
In order to ensure safety against the vulnerability reported by VU#854306 and VU#107186, the test cases at http://www.ee.oulu.fi/research/ouspg/protos/testing/c06/snmpv1/ were executed, with no adverse effect on the NetConnect. The Stinger NetConnect passed all of the test cases.
