One of the very few examples that sound reasonable,  is dhclient.
Apparently,  that can be readily used for this bug to be exploited. Sounds
like more of problem with dhclient,  though.

I agree that there's a lot of fud out there about this bug; once found (or
perhaps: cve assigned), the patches came quickly, so that actually looks
quite good for bash!

Switching /bin/sh to dash has been discussed before and we can spend a lot
of e-mails on that, but as usual it's up to devs to implement it as such,
or not.

Just my E0, 02

Mvg,  Guus
