It depends on which version of Red Hat Linux you're running.  There have
been a number of kernel fixes that plug undesired escalations in
privilege.  If somebody were to hack in via the webserver and get a
local user account, they could then escalate their privs and become
root.

If it was an internal server, I'd leave it alone (and have, locally).
For external-facing systems, patch and reboot when required.
