Good news, Mac users. Apple just released an update for OS X that fixes a security flaw in the Bash UNIX shell. This is the part of the software that's vulnerable to the Shellshock bug uncovered last week. And although the vulnerability only affects a small number of Mac users, a fix is certainly welcome.

Before you go downloading, you should check which version of OS X you're running. Mavericks users can download the OS X bash update 1.0 here. Lion and Mountain Lion users can download their bash updates here and here, respectively. There's no need to wait by the way. This bug is kind of a big deal, so you should act fast. [9to5 Mac]
