Vulnerability description

On September 24, 2014, a vulnerability in the Bash shell was publicly announced. The vulnerability is related to the way in which shell functions are passed though environment variables.

The Bash shell may be invoked by a number of processes including, but not limited to, telnet, SSH, DHCP, and scripts hosted on web server
