net-snmp: NULL pointer exception in snmp_oid_compare in snmplib/snmp_api.c resulting in a denial of service
snmp_oid_compare in snmplib/snmp_api.c in Net-SNMP before 5.8 has a NULL Pointer Exception bug that can be used by an unauthenticated attacker to remotely cause the instance to crash via a crafted UDP packet, resulting in Denial of Service.
Mitigation: Configuring snmp with a secret community string makes this attack much more difficult to perform, as the attacker must guess the community string in order to exploit the vulnerability.
Protecting the snmp service with host firewall rules to prevent unauthorized hosts from sending messages to the snmp service will prevent this attack being carried out by users of other hosts on the network.
Either or both of these steps is recommended
