Hello,

I have decided to create fixed bash packages for Debian Lenny. I have applied the upstream patchsets from from 052 until 057, so some other issues are also addressed in it. :-)
And here they are:

Source .dsc: http://misc.linux-dev.org/bash_shellshock/bash_3.2-4.1.dsc
amd64 package: http://misc.linux-dev.org/bash_shellshock/bash_3.2-4.1_amd64.deb
i386 package: http://misc.linux-dev.org/bash_shellshock/bash_3.2-4.1_i386.deb

Much fun with it!
