Just a quick update on the Bash vulnerability we mentioned in this post.
Apple have released Bash fixes for OS X Lion, Mountain Lion and Mavericks. The fixes are expected to be available from Software Update in the next day or so (it already appears to be available in the US) and standalone patches are also available if you don’t want to wait.
Apple are confident that the vast majority of users will not be affected by the vulnerability (see New York times blog post for more info); anyone who has fiddled with settings is the most at risk.
