Apple on Monday said it has now patched
the Bash vulnerability for its OS X Lion, Mountain Lion and Mavericks
software. The company also created a site for users to download the
Bash update.

Apple stated that most Mac users were
safe from Shellshock as remote services like web sharing are disabled
by default. OS X Server users were not mentioned but I consider them
to be at far more risk as it is much easier to set up and enable a
web server or other remote services. However this bug was serious
enough to get Apple’s immediate attention and today they released a
software patch “OS X bash Update 1.0?. Strangely this update can
not be found through the normal software update process but has to be
downloaded from Apple’s website.
