While reviewing mail today, I came across this post (below) to
vuln-dev (at) security-focus (dot) com [email concealed], dated 07/24/2002. We've been tracking this
vulnerability as VU#438955, but have not seen any responses from the
various OS vendors that ship bash. Do you know whether any Unix or Linux
vendors have upgraded their version of bash to address this vulnerability?
