For Shellshock issue I upgrade bash on redhat 4,5 use the follow steps

  1. check bash version

    root@aaaA:/usr/src/redhat/RPMS/x86_64>bash --version GNU bash, version 3.2.25(1)-release (x86_64-redhat-linux-gnu) Copyright (C) 2005 Free Software Foundation, Inc.

  2. upgrade bash

    rpmbuild --rebuild -bb bash-3.2-33.el5_11.4.src.rpm
    cd /usr/src/redhat/RPMS/x86_64/
    root@aaa:/usr/src/redhat/RPMS/x86_64>rpm -Uvh bash-* Preparing... ########################################### [100%] 1:bash ########################################### [ 50%] 2:bash-debuginfo ########################################### [100%]

  3. check bash version again

root@aaa:/usr/src/redhat/RPMS/x86_64>bash --version GNU bash, version 3.2.25(1)-release (x86_64-redhat-linux-gnu) Copyright (C) 2005 Free Software Foundation, Inc.

  1. reboot and check bash version again

root@aaa:/usr/src/redhat/RPMS/x86_64>bash --version GNU bash, version 3.2.25(1)-release (x86_64-redhat-linux-gnu) Copyright (C) 2005 Free Software Foundation, Inc.

  1. check rpm

root@aaa:/usr/src/redhat/RPMS/x86_64>rpm -qa | grep bash bash-3.2-33.4 bash-debuginfo-3.2-33.4

Why bash version no change to bash-3.2-33.4

    did the new installation installed newer bash executable to another location that what's in your PATH. do which bash and whereis bash, try bash --version from all those bash executables. if you find a newer one, put that's file's path first in order in $PATH – AKS Sep 29 '14 at 17:19

    see if this helps! https://access.redhat.com/solutions/1207723 – AKS Oct 01 '14 at 16:32
  • ANS.That's normal. Red Hat usually backports the fix to the existing version. bash -version will not show any difference in the output post update. – user3509785 Oct 03 '14 at 06:47
