That means it is using the OS zlib to build things. If RHEL does not ship
any update, then rebuilding it won't fix anything.

If you backport the fix to the shipped zlib source code and build it
yourself, then if all goes well everything which was built against the
original ABI will continue to work without recompiling

If you compile a new zlib then you may need to recompile it but also every
other spec that requires zlib-devel.
