Security readout for executives and security teams

CVE-2009-1887 is a remote denial-of-service issue in net-snmp on RHEL 3. A malformed SNMP GETBULK request can crash the snmpd daemon through a divide-by-zero condition, disrupting SNMP-based monitoring or management until the service is restored. Likely exposure is limited to legacy systems running vulnerable net-snmp packages, especially RHEL 3 systems with snmpd reachable over the network. Risk increases when SNMP is exposed beyond trusted management networks. Treat this as a legacy exposure cleanup item. It is not cited as actively exploited, but exposed SNMP on old systems can disrupt visibility and operations. Mitigation focus: Apply the applicable Red Hat RHSA-2009:1124 net-snmp update where relevant.; Review Mandriva MDVSA-2009:156 if managing affected Mandriva packages.; Restrict SNMP access to trusted management networks only..
