CentOS 3 : net-snmp (CESA-2009:1124)

medium Nessus Plugin ID 39523

Synopsis

The remote CentOS 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.

Solution

Update the affected net-snmp packages.
