(RHSA-2008:0971) Important: net-snmp security update

The Simple Network Management Protocol (SNMP) is a protocol used for
network management.

A denial-of-service flaw was found in the way Net-SNMP processes SNMP
GETBULK requests. A remote attacker who issued a specially-crafted request
could cause the snmpd server to crash. (CVE-2008-4309)

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 users of net-snmp should upgrade to these updated packages, which
contain a backported patch to resolve this issue.
