Fixing Shellshock on ubuntu 12.10

Took a while to fix the shellshock vulnerability (did not have the kind of services that makes my host vulnerable). As is ubuntu 12.10, a simple apt-get update does not work:

leonardo@pike:~$ x=’() { :;}; echo ? VULNERABLE’ bash -c :

VULNERABLE

leonardo@pike:~$ wget http://security.ubuntu.com/ubuntu/pool/main/b/bash/bash_4.2-2ubuntu2.5_amd64.deb

leonardo@pike:~$ sudo dpkg -i bash_4.2-2ubuntu2.5_amd64.deb

leonardo@pike:~$ x=’() { :;}; echo VULNERABLE’ bash -c : leonardo@pike:~$
