SuSE 11.3 Security Update : bash (SAT Patch Number 9780)

This script is Copyright (C) 2014-2016 Tenable Network Security, Inc.


Synopsis :

The remote SuSE 11 host is missing one or more security updates.

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 :

- Nested HERE documents could lead to a crash of bash.
(CVE-2014-7186)

- Nesting of for loops could lead to a crash of bash.
(CVE-2014-7187)
