Security concern on Server edition files

Hi, looking at the Server edition, it looks to me like the mode bits for all of the non-executable files (e.g., the DLLs and the like - code files, not user data files) are 666. This is almost certainly a security concern, and they should be updated to something more like 660 or 600.

@lubos I realized I should have specified - this is the Linux server edition. Feel free to have someone reach out to me if it’s unclear why this is a security risk, I’m happy to help.
