comment Are Macs vulnerable to the Bash shellshock bug?
In fact, your answer is totally wrong!!! Ordinary ssh usage isn't vulnerable since you're already opening a shell, only ssh's restricted login command is vulnerable. Almost no Linux users even know about that, so like no Mac users do.

As I said below, ALL servers should be assumed to call bash unless proven otherwise. And Mac OS X is full of privilege escalation exploits once you reach a shell.

Apache modules, CGI scripts, etc. commonly call bash. Very effective hack right here : twitter.com/JZdziarski/status/515135854436962304 And even if your Apache configuration does not call bash under normal operation, no telling what an attacker can convince it to do.

How do you know that? Initial advisory was a vulnerable DHCP client. And many articles speculate that Mac OS X and/or iOS DHCP clients might be vulnerable. All servers should be assumed to be vulnerable unless proven otherwise.

There are likely privilege escalation risks from a guest account too. Who cares though? Any Mac OS X machines is extremely vulnerable once users get access, especially local users. It's server daemons that should scare you, not just sshd though, all server daemons.

-1 Very wrong. There are many tools that use bash : Installation scripts usually use bash, creating privilege escalation risks. All servers should be assumed to use bash unless you know otherwise, not just sshd. In particular, apache could create a remote vulnerability using bash. etc.
