openSUSE 13.1: 2014:1242-1 Critical Problems with Core Shell Functionality

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.
