**Name of the Vulnerable Software and Affected Versions** Elecsys Director Gateway devices with kernel 2.6.32.11ael1 and earlier **Description** The issue allows remote attackers to cause a denial of service, resulting in CPU consumption and communication outage, via crafted input to the DNP3 service in the Outstation component. **Recommendations** For kernel versions 2.6.32.11ael1 and earlier, consider disabling the DNP3 service in the Outstation component as a temporary workaround to minimize the risk of exploitation.

**Name of the Vulnerable Software and Affected Versions** SubSTATION Server versions 2.7.0033 through 2.8.0106 **Description** The issue concerns the DNP3 Slave service, which allows remote attackers to cause a denial of service. This can be achieved through unspecified vectors, resulting in an unhandled exception and process crash. **Recommendations** For versions 2.7.0033 through 2.8.0106, consider disabling the DNP3 Slave service as a temporary workaround until a patch is available. Restrict access to the service to minimize the risk of exploitation.
