Description

The remote host is missing updates announced in 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.
