-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 ======================================================
Updated net-snmp packages that fix a security issue are now available for Red Hat Enterprise Linux 3

Solution

Before applying this update, make sure that all previously-released errata relevant to your system have been applied.

This update is available via Red Hat Network. Details on how to use the Red Hat Network to apply this update are available at

Summary

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.
