Summary
Important: zsh security update
Details

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: insecure dropping of privileges when unsetting PRIVILEGED option (CVE-2019-20044)
