your first step is to create a patch[1] and submit that to the project's issue queue[2]. you don't need CVS access to fix something. as always, please search for existing issues about the bugs you've fixed before you create a new one, to avoid duplicates. also, in general, it's better to fix different bugs in different patches, so that each individual fix is easier to review/test/commit.
