September 28, 2014
Apple says users of its OS X are “safe by default” from the Bash Bug, meanwhile Oracle warns its customers that 32 products are affected by the flaw.
The Bash Bug exploit reportedly affects most Linux and Unix-based OSs, including OS X.
In contrast, Apple declares the vast majority of Mac computers are not at risk from the Bash Bug
, aka the “Shellshock” bug, the company has issued a public statement in response to the critical security issue.
“The vast majority of OS X users are not at risk to recently reported bash vulnerabilities,” states the Apple public statement.”Bash, a UNIX command shell and language included in OS X, has a weakness that could allow unauthorized users to remotely gain control of vulnerable systems. With OS X, systems are safe by default and not exposed to remote exploits of bash unless users configure advanced UNIX services. We are working to quickly provide a software update for our advanced UNIX users.“
The majority of Apple OS X users is
considered to be safe so long as they haven’t configured any advanced access to their systems, anyway the company announced the distribution of an OS X update to fix the Bash Bug
This means that Apple OS X users have to disable any advanced UNIX options waiting for the patch will be issued.
According security experts it ‘s
very likely that the vulnerability has already been exploited, a system administrator using the @yinettesys Twitter account published a GitHub gist post
reporting on a case
in which threat actors exploited the Bash Bug flaw to launch kernel
exploit on machine coordinating the attack with a C&C server hidden behind the Cloudflare content delivery network.
