bash version doesn't change after shellshock update

I noticed that the bash version (bash --version) did not change after applying the updated rpm. RPM reports the correct version number and the RH vulnerability checker script says everything is good. I even tried rebooting the server; nothing changed. This happened in RHEL5 32-bit & 64-bit and RHEL4 32-bit. Has anyone else seen this behavior?
