CVE-2018-18066
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.
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (3.59%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
