RHEL 3 : net-snmp (RHSA-2009:1124)

This script is Copyright (C) 2009-2014 Tenable Network Security, Inc.


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.

A divide-by-zero flaw was discovered in the snmpd daemon. A remote
attacker could issue a specially-crafted GETBULK request that could
crash the snmpd daemon. (CVE-2009-1887)

Note: An attacker must have read access to the SNMP server in order to
exploit this flaw. In the default configuration, the community name
'public' grants read-only access. In production deployments, it is
recommended to change this default community name.

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.
