A major security flaw that could affect Apple's Mac and Linux operating systems has been discovered, with security experts claiming it to be more dangerous than the recent Heartbleed bug.
The Shellshock bug creates a vulnerability in "Bash" – a software that controls the command prompt on many computers running the Unix operating system. The command prompt is integral to the running of computers and is behind simple tasks such as opening up an application. The Shellshock bug could therefore allow hackers to access and control a system remotely
"It is that interface that makes things happens. It is unlikely that there is Linux-based system that doesn't run Bash, it's pretty huge," Ernest Hilbert, former FBI agent and head of cyber investigations for EMEA at risk consultancy Kroll, told CNBC by phone.
Bigger than Heartbleed
Apple's Mac OS X and Linux-based systems could be open to attack with security experts warnings that this vulnerability could be more damaging than the Heartbleed bug discovered in April.
