GNU Bash Environment Variable Handling Code Injection (Shellshock)


The remote web server is affected by a command injection vulnerability in GNU Bash known as Shellshock. The vulnerability is due to the processing of trailing strings after function definitions in the values of environment variables. This allows a remote attacker to execute arbitrary code via environment variable manipulation depending on the configuration of the system.


Apply the referenced patches to address both CVE-2014-6271 (Shellshock original vulnerability) and CVE-2014-6278 which is a bypass for the CVE-2014-6271 fix.
