That is not the way to check if you have the update installed.  That is
the major upstream bash version on which the Red Hat version is based
... this will likely never change throughout the lifetime of each
individual man branch of CentOS .. that is, CentOS-5 will likely always
say 3.2.25(1)-release, CentOS-6 will likely always say 4.1.2(1)-release,
etc.

What you need to do to check the version is this:

rpm -q bash

the result should be (if you have the update):

for c5:   bash-3.2-33.el5.1

for c6:   bash-4.1.2-15.el6_5.1

for c7:   bash-4.2.45-5.el7_0.2

Note: Some people may have ARCH enabled in their RPM commands, so a
.i386, .i686, .x86_64 might be on the end of the above output, so for
c7, it might say:  bash-4.2.45-5.el7_0.2.x86_64

Thanks,
