Fedora 31: FEDORA-2021-1234567g8h Critical: Bash Security Leak

The zsh shell is a command interpreter usable as an interactive login

shell and as a shell script command processor. Zsh resembles the ksh

shell (the Korn shell), but includes many enhancements. Zsh supports

command line editing, built-in spelling correction, programmable

command completion, shell functions (with autoloading), a history

mechanism, and more.
