## Overview

A buffer overflow vulnerability exists in a system service within the underlying operating system of HPE Networking EdgeConnect SD-WAN Gateways that could allow an unauthenticated adjacent attacker to cause a denial-of-service. Successful exploitation could allow an attacker to crash the impacted service and temporarily disrupting network operations.

## Affected

- `edgeconnect_sd-wan_orchestrator >= 9.4.0, < 9.4.11`
- `edgeconnect_sd-wan_orchestrator >= 9.5.0, < 9.5.9`
- `edgeconnect_sd-wan_orchestrator >= 9.6.0, < 9.6.4`
- `edgeconnect_sd-wan_orchestrator = 9.7.0`
- `edgeconnect_operating_system >= 9.4.0.0, < 9.4.9.0`
- `edgeconnect_operating_system >= 9.5.0.0, < 9.5.9.0`
- `edgeconnect_operating_system >= 9.6.0.0, < 9.6.4.0`
- `edgeconnect_operating_system = 9.7.0.0`

## Remediation

Upgrade past the affected range:

- `edgeconnect_sd-wan_orchestrator 9.6.4`
- `edgeconnect_operating_system 9.6.4.0`
