A vulnerability in bash is affecting all kinds of *nix systems and some Cisco collaboration products are affected. Cisco has identified the vulnerable software and has either patched or is in the process of building patches.
The PSIRT is by far the best place to look for vulnerable software as well as to look at each BugID to find patched software
