Avoiding accidental updates is as easy as putting exclusion rules in
your yum repo files. I do this routinely to prevent my OOo 2.4.1 from
getting overwritten by (and me getting notices for) "newer" revisions
of older base versions. (Exclusion rules don't care which way the
update would go, up or down.)
