That's only mean than in zsh you cannot do something like:
stty -echo #turn off echoing what you type
stty echo #turn on echoing
reset #reset terminal to the default state
In bash, the above command works as expected - turn off echoing of command. Just tried in zsh - does not work. Who has a bug? ;)
Turning off echoing is possible achieve with ESC sequences, so if your program randomly send binary sequences to terminal, {or when you CTRL-\ some screen oriented program),it behaves sometimes like stty -echo and you must reset it. It is not a bug - simply it is how terminals (and terminal emulators) works.
What is strange, why in zsh stty -echo does not works.

No, it doesn't affect ZSH.
You still MUST update bash as most of the system scripts are written for bash and vulnerable to the shellshock bug.
To test your ZSH do this:
What exactly does this code do?
env x='() { :;}; echo vulnerable'creates an environment variable with known bug using command in the end of variablezsh -c 'echo hello'launches ZSH shell with simple hello (and evaluating all env variables including x)If you see output:
Then your ZSH is vulnerable. Mine (5.0.2) is not:
