The command-line shell 'bash' evaluates environment variables, whichallows the injection of characters and might be used to access files onthe system in some circumstances (CVE-2014-7169).Please note that this issue is different from a previously fixedvulnerability tracked under CVE-2014-6271 and it is less serious due tothe special, non-default system configuration that is needed to create anexploitable situation.To remove further exploitation potential we now limit thefunction-in-environment variable to variables prefixed with BASH_FUNC_ .This hardening feature is work in progress and might be improved in laterupdates.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.
