CVE-2014-6271 and CVE-2014-7169 – ShellShock
Important
Canonical Ubuntu, CentOS
GNU Bash through 4.3 processes trailing strings after function definitions in the values of environment variables, which allows remote attackers to execute arbitrary code via a crafted environment, as demonstrated by vectors involving the ForceCommand feature in OpenSSH sshd, the mod_cgi and mod_cgid modules in the Apache HTTP Server, scripts executed by unspecified DHCP clients and other situations in which setting the environment occurs across a privilege boundary from Bash execution.
The Cloud Foundry project is in the process of checking if Cloud Foundry are vulnerable to remote code execution or other exploits. No exploits have been identified or confirmed yet. The Cloud Foundry project is patching all components that have packaged the vulnerable version of bash.
_Severity is important unless otherwise noted.

Users of affected versions should apply the following mitigation:
