Do you send alerts when DirectX 9 Runtime software vulnerabilities are identified? If yes, I would like to be on the distribution list. If no, what's the best way to find this information on your website?
Vulnerabilities for DirectX 9 were fully fixed when Vista Service Pack 1 was released. There haven't been any alerts until now from that period. The current version of DirectX 9 is stable. The latest updated version is released on June 2010 and you can download it using the following URL: https://www.microsoft.com/en-US/download/details.aspx?id=8109
Updated to Microsoft components are deployed through Windows Update. You can turn that on to receive updates and fixes. No notification will be provided to you, though.
