Affected: AlmaLinux:8: zsh, AlmaLinux:8: zsh-html
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.
Security Fix(es):
* zsh: Prompt expansion vulnerability (CVE-2021-45444)

In zsh before 5.8.1, an attacker can achieve code execution if they control a command output inside the prompt, as demonstrated by a %F argument. This occurs because of recursive PROMPT_SUBST expansion.

The zsh is a shell designed for interactive use, and it is also a powerful scripting language. Many of the useful features of bash, ksh, and tcsh were incorporated into zsh. It can match files by file extension without running an external program, share command history with any shell, and more.
