A possibility of sensitive host information disclosure was found in the 
implementation of SNMP protocol as defined in RFC 1065, RFC 1066, and RFC 1067.
If the snmpd deamon was running on the host, it served the SNMP queries
regardless of the fact, the IP address of the requester was not mentioned in
the list of hosts allowed to issue / request SNMP MIB objects information.
Remote attacker could use this flaw to gain host related sensitive information
via performing a SNMP query.

Common Vulnerabilities and Exposures assigned an identifier CVE-2008-6123 to
the following vulnerability:

The netsnmp_udp_fmtaddr function (snmplib/snmpUDPDomain.c) in net-snmp
5.0.9 through 5.4.2, 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."
