advisory RHSA-2009:0295.

The Simple Network Management Protocol (SNMP) is a protocol used for
network management.

It was discovered that the snmpd daemon did not use TCP wrappers correctly,
causing network hosts access restrictions defined in /etc/hosts.allow and
/etc/hosts.deny to not be honored. A remote attacker could use this flaw
to bypass intended access restrictions. (CVE-2008-6123)

This issue only affected configurations where hosts.allow and hosts.deny
were used to limit access to the SNMP server. To obtain information from
the server, the attacker would have to successfully authenticate, usually
by providing a correct community string.

All net-snmp users should upgrade to these updated packages, which contain
a backported patch to correct this issue. After installing the update, the
snmpd and snmptrapd daemons will be restarted automatically.");
