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.
After installing the update, the snmpd and snmptrapd daemons will be restarted automatically.
