Security readout for executives and security teams
This is a legacy remote code execution issue in the Informix Storage Manager Portmapper service. A remote attacker could send malformed authentication data that causes a stack buffer overflow. Business urgency is highest where old IBM Informix IDS or EMC Legato NetWorker systems still expose this service. Exposure is most likely in legacy IBM Informix Dynamic Server 10.x before 10.00.TC9, 11.x before 11.10.TC3, or EMC Legato NetWorker deployments using the affected ISM Portmapper/librpc.dll component. Public exposure of portmapper-like services increases urgency. Prioritize remediation for any internet-reachable or broadly reachable legacy database or backup infrastructure. If the service is internal-only and access-controlled, schedule prompt patching and exposure reduction, but first confirm whether affected versions remain in production. Mitigation focus: Upgrade IBM Informix IDS 10.x to 10.00.TC9 or later where applicable.; Upgrade IBM Informix IDS 11.x to 11.10.TC3 or later where applicable.; Check EMC guidance for affected Legato NetWorker versions and fixes..
