I have a general idea about the Shellshock bash bug (CVE-2014-6271 reported Sep 24, 2014) of what the vulnerability is and how it could be exploited. Here you find examples on how to exploit the original bug CVE-2014-6271: What is a specific example of how the Shellshock Bash bug could be exploited?
Meanwhile, a patch is out on most major distributions which fixes the initial, although not the full, Shellshock vulnerability.
There is a patch that prevents bash from interpreting anything else than the function definition in there (https://lists.gnu.org/archive/html/bug-bash/2014-09/msg00081.html), and that's the one that has been applied in all the security updates from the various Linux distributions.
However, bash still interprets the code in there and any bug in the interpreter could be exploited. One such bug has already been found (CVE-2014-7169) though its impact is a lot smaller. So there will be another patch coming soon.
CVE-2014-7169 appears to be less severe but is definitely still cause for concern. So how would an example exploit look like for this remaining bug?
