RHEL 3 : net-snmp (RHSA-2009:0295)

Synopsis :

The remote Red Hat host is missing one or more security updates.

Description :

Updated net-snmp packages that fix a security issue are now available
for Red Hat Enterprise Linux 3.

This update has been rated as having moderate security impact by the
Red Hat Security Response Team.

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.
