1. Vulnerabilities of Remote Desktop Service for Windows
   Microsoft Corp. has disclosed vulnerabilities (CVE-2019-0708, CVE-2019-1181 and CVE-1182) of remote desktop service (software for remote control from other computers) installed in the Windows OS. An attacker who successfully exploited these vulnerabilities could install programs, display, modify, or delete data.
2. Impacts on our products
   Remote Desktop Services is enabled on some of our MRI, CT, and X-ray diagnostic imaging system products. We judge that the impact of this vulnerability is small in the assumed network environment. At the request of the customer, it is possible to take measures such as disabling the remote desktop service. Please contact the sales office where you purchased the product.
   All other products are not affected by these vulnerabilities because the OS that contains these  vulnerabilities is uninstalled, or Remote Desktop Services is disabled.
