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 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.
