The risk of cyber incidents impacting the grid\u0027s reliability can thus be minimized by virtue of the grid design.\n\nSiemens Energy strongly recommends applying the provided security updates using the corresponding tooling and documented procedures made available with the product. If supported by the product, an automated means to apply the security updates across multiple product instances may be used. Siemens Energy strongly recommends prior validation of any security update before being applied, and supervision by trained staff of the update process in the target environment.\n\nAs a general security measure Siemens Energy strongly recommends to protect network access with appropriate mechanisms (e.g. firewalls, segmentation, VPN). It is advised to configure the environment according to our operational guidelines in order to run the devices in a protected IT environment.",

If supported by the product, an automated means to apply the security updates across multiple product instances may be used. Siemens Energy strongly recommends prior validation of any security update before being applied, and supervision by trained staff of the update process in the target environment.\n\nAs a general security measure Siemens Energy strongly recommends to protect network access with appropriate mechanisms (e.g. firewalls, segmentation, VPN). It is advised to configure the environment according to our operational guidelines in order to run the devices in a protected IT environment.",

Vulnerability from variot
A DNS client stack-based buffer overflow in ipdnsc_decode_name() affects Wind River VxWorks 6.5 through 7. NOTE: This vulnerability only affects products that are no longer supported by the maintainer. Wind River VxWorks Is vulnerable to an out-of-bounds write.Information is obtained, information is tampered with, and service is disrupted (DoS) It may be put into a state. Wind River VxWorks is an operating system of Wind River Company in the United States. The industry-leading real-time operating system for building embedded devices and systems. Remote attackers can use this vulnerability to submit special requests, causing the application to crash or execute arbitrary code in the application context
