The strings of issues around bash is very heavily dynamic.
Distros (or individuals) that leveraged the fixes originally provided by Florian Weimer are properly shielded from these additional flaws. Unfortunately aside from Red Hat (Florian's employer) few took these on initially and deferred to alternate upstream solutions. Chad & team have now accepted the Red Hat fixes into the upstream and many vendors have in turn pulled those down.
It is expected there very well could be additional issues discovered but hopefully the worst have been properly addressed already.
