Detail
| A security issue affects these releases of Ubuntu and its derivatives: - Ubuntu 14.04 LTS - Ubuntu 12.04 LTS - Ubuntu 10.04 LTS Summary: Several security issues were fixed in Bash. Software Description: - bash: GNU Bourne Again SHell Details: Florian Weimer and Todd Sabin discovered that the Bash parser incorrectly handled memory. An attacker could possibly use this issue to bypass certain environment restrictions and execute arbitrary code. (CVE-2014-7186, CVE-2014-7187) In addition, this update introduces a hardening measure which adds prefixes and suffixes around environment variable names which contain shell functions. Update instructions: The problem can be corrected by updating your system to the following package versions: Ubuntu 14.04 LTS: Ubuntu 12.04 LTS: Ubuntu 10.04 LTS: In general, a standard system update will make all the necessary changes.

| Title: | SUSE-SU-2014:1247-1 -- Security update for bash | ||
| 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.
