GOT2000 Series TCP/IP Stack Vulnerabilities Technical Bulletin

This technical bulletin addresses multiple TCP/IP stack vulnerabilities discovered in CoreOS version Y and earlier on GOT2000 Series (GT27, GT25, GT23) models, which could allow network function disruption or malicious code execution via crafted TCP packets. The recommended countermeasure is to install CoreOS version Z or later using GT Designer3 version 1.240A or later, and to restrict network access to trusted sources.
