[security-announce] SUSE-SU-2014:1247-2: important: Security update for bash
SUSE Security Update: Security update for bash
______________________________________________________________________________

Announcement ID: SUSE-SU-2014:1247-2
Rating: important
References: #898346 #898603 #898604
Cross-References: CVE-2014-7169 CVE-2014-7186 CVE-2014-7187

Affected Products:
SUSE Manager 1.7 for SLE 11 SP2
______________________________________________________________________________

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.
