Shellshock: ‘Deadly serious’ new vulnerability found

More than 500 million computers could be affected, early estimates suggest.

A “deadly serious” bug potentially affecting hundreds of millions of computers, servers and devices has been discovered

(SOURCE)  The flaw has been found in a software component known as Bash, which is a part of many Linux systems as well as Apple’s Mac operating system.

The bug, dubbed Shellshock, can be used to remotely take control of almost any system using Bash, researchers said.

Experts said it was more serious than the Heartbleed bug discovered in April.

“Whereas something like Heartbleed was all about sniffing what was going on, this was about giving you direct access to the system,” Prof Alan Woodward, a security researcher from the University of Surrey, told the BBC.

“The door’s wide open.”

Some 500,000 machines worldwide were thought to have been vulnerable to Heartbleed. But early estimates, which experts said were conservative, suggest that Shellshock could hit at least 500 million machines.

The problem is particularly serious given that many web servers are run using the Apache system, software which includes the Bash component.
