NVD Description

Note: Versions mentioned in the description apply only to the upstream bash package and not the bash package as distributed by Ubuntu. See How to fix? for Ubuntu:16.04 relevant fixed versions and status.

rbash in Bash before 4.4-beta2 did not prevent the shell user from modifying BASH_CMDS, thus allowing the user to execute any command with the permissions of the shell.
