openSUSE Security Update : bash (openSUSE-SU-2014:1229-1) (Shellshock)

This script is Copyright (C) 2014-2015 Tenable Network Security, Inc.


Synopsis :

The remote openSUSE host is missing a security update.

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 it 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.

Additionaly two more security issues were fixed in bash:
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.
