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

critical Nessus Plugin ID 77958

Language:

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)

Solution

Apply SAT patch number 9780.
