   An update that fixes three vulnerabilities is now available.

Description:


   The command-line shell 'bash' evaluates environment variables, which
   allows the injection of characters and might be used to access files on
   the system in some circumstances (CVE-2014-7169).

   Please note that this issue is different from a previously fixed
   vulnerability tracked under CVE-2014-6271 and is less serious due to the
   special, non-default system configuration that is needed to create an
   exploitable situation.

   To remove further exploitation potential we now limit the
   function-in-environment variable to variables prefixed with BASH_FUNC_.
   This hardening feature is work in progress and might be improved in later
   updates.

   Additionally, two other security issues have been fixed:

       * CVE-2014-7186: Nested HERE documents could lead to a crash of bash.
       * CVE-2014-7187: Nesting of for loops could lead to a crash of bash.
