Hi, How do we go about this fix for the servers. We are using Win2003 standard, Win2003 R2 and Win2008 standard 64 bit. Is there a utility tools to run and check that are in the vulnerability ?
Patching the wrong firmware will be disaster.
You will need to check with the manufacturer of your systems to obtain a BIOS update that includes the microcode versions that mitigate this issue. If your servers are from Intel (vs. Dell, HP etc.) then you can find information here: https://www.intel.com/content/www/us/en/support/articles/000028721/server-products.html https://www.intel.com/content/www/us/en/support/articles/000028721/server-products.html
You will also need to check with Microsoft to obtain the security patches for your servers.
There is not a super easy tool that can tell you if a system is vulnerable, but this page from Microsoft has details on using PowerShell to determine if a system is vulnerable: https://support.microsoft.com/en-us/help/4072698/windows-server-guidance-to-protect-against-the-spec... https://support.microsoft.com/en-us/help/4072698/windows-server-guidance-to-protect-against-the-spec... (this page also has information on mitigating side-channel vulnerabilities disclosed earlier this year)
