QID 671081: EulerOS Security Update for zsh (EulerOS-SA-2019-2705)

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): in zsh before 5.3, an off-by-one error resulted in undersized buffers that were intended to support path_max characters.(cve-2016-10714)
