ucd-snmp < 4.2.3 - Remote Code Execution via snmpnetstat Heap Overflow
Heap-based buffer overflow in snmpnetstat for ucd-snmp 4.2.3 and earlier, and net-snmp, allows remote attackers to execute arbitrary code via multiple getnextrequest PDU messages with conflicting ifindex variables, which cause snmpnetstat to write variable data past the end of an array.
