‘Catastrophic’ flaw may threaten the security of millions of devices connected to the internet

Experts are warning about a 'catastrophic' security flaw that may threaten the security of millions of devices connected to the Internet.

Known as the 'Bash' bug, the flaw could be 'bigger than Heartbleed' which put every computer user at risk earlier this year.

Experts claim the bug may pose a serious threat to computers using Unix-based operating systems, including Linux and Apple's Mac OS X -- and in turn, could spread to all Internet-connected devices.
