Descriptions

The netsnmp_udp_fmtaddr function (snmplib/snmpUDPDomain.c) in net-snmp 5.0.9 through 5.4.2.1, when using TCP wrappers for client authorization, does not properly parse hosts.allow rules, which allows remote attackers to bypass intended access restrictions and execute SNMP queries, related to "source/destination IP address confusion."

La función netsnmp_udp_fmtaddr (snmplib/snmpUDPDomain.c) en net-snmp v5.0.9 hasta v5.4.2, cuando usando TCP wrappers para autorización de clientes, no analiza apropiadamente reglas hosts.allow, lo que permite a los atacantes remotos evitar restricciones de accesos intencionados y ejecuta consultas SNMP, relativas a "direcciones IP fuente/destino confusas".
