1) Input validation error (CVE-ID: CVE-2008-6123)
The vulnerability allows a remote non-authenticated attacker to gain access to sensitive information.
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."
