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.
