Don't go blindly making changes like this without researching the
implications.  You don't know any of us here and occasionally some
posters will give out bad advice (I've even been known to be wrong once
or twice).

Exactly.  Every package you replace from Red Hat's distribution puts you
farther and farther from a stable, supported operating system release
unless you're going to be watching for all the fixes for every one of
those packages and understand *exactly* how fixes are going to be
handled by the upstream providers.

Red Hat's policies for fixing security holes are different than other
providers.  Red Hat won't, unless absolutely necessary, break binary
compatibility within a release.  In other words, they'll backport the
fix so that every other package still works without changes.  Other
providers simply give you the "latest and greatest" and you may need to
re-compile other application or in some cases update the code.  ssl is a
very good example of this.

In short, you're paying Red Hat a lot of money to give you a stable and
secure set of packages.  Don't replace them blindly.
