Net-SNMP 5.7.1 and earlier, when AgentX is registering to handle a MIB and processing GETNEXT requests, allows remote attackers to cause a denial of service (crash or infinite loop, CPU consumption, and hang) by causing the AgentX subagent to timeout. (CVE-2012-6151)
Impact
If an attacker can disrupt or delay SNMP messages, it is possible to cause an SNMP daemon crash or excessive CPU usage. Partial availability impact as SNMP services are not required for the Traffic Management Microkernel (TMM) to process traffic.
