A remote, unauthenticated attacker could use this flaw to crash snmpd or potentially execute arbitrary code on the system with the privileges of the user running snmpd. - CVE-2018-18065 (denial of service) A denial of service vulnerability has been discovered in net-snmp before 5.8. The _set_key function in agent/helpers/table_container.c has a NULL pointer exception bug that can be used by an authenticated attacker to remotely cause the instance to crash via a crafted UDP packet, resulting in denial of service. Impact ====== A remote unauthenticated attacker is able to crash snmpd or potentially execute arbitrary code on the system by sending specially crafted packets.
