Again: NO, it is NOT a security issue.
Repeat after me: this is NOT a security issue.

If you're system is configured so that users actually can open and
read the paging file you don't need to worry about security issues
anymore. Because you don't have any security at all and therefore
can't have any issues with it. Can't have an issue with something that
doesn't exist.

So you're expecting a process to implement the security because your
system doesn't?
Doesn't work that way, sorry. If your system is not secure, all that a
process can do is provide "security by obscurity" - look it up if you
don't know what that is.
