#
# Method of upgrading bash on Debian 5.0, in order to fix
# the vulnerability "shellshock", officially known as:
#
#   CVE-2014-6271
#   CVE-2014-7169
#
# The credit for this belongs to user "cft" on Hacker News,
# for upgrading Ubuntu 8.04: https://news.ycombinator.com/item?id=8371438
#
# It worked for me, but no warranties, express or implied.
#
# While this should also work for Debian 6 (Squeeze), there is an LTS apt
# repository providing security updates until February, 2016.  Instructions
# for using LTS can be found at https://wiki.debian.org/LTS
