AFAIK, we are still vulnerable to CVE-2014-6277 and CVE-2014-6278, but not
through any interesting attack vectors: Debian included the RedHat change
that moves the functions to the BASH_FUNC_<name>() namespace in the DSA-3035
fix.
However, should someone find a way to inject BASH_FUNC_foo()='<whatever
triggers these undisclosed bugs>' into the environment, the attack is going
to succeed. To twart that, we have to wait until the embargo is lifted and
the real fix for CVE-2014-6277 and CVE-2014-6278 gets uploaded/published.
